@TheOutdoorGearReview : I noticed something: that backpack bottom is just too soft, or fragile! If you can, take and cut up an old tire tread that you can fit across the bottom of that pack, and Hot-Glue it onto the pack-bottom. It'll save against lots of punctures, and tears!
@@tarhit9 Thank you for validating your ignorance with your baseless and asinine assumptions - how progressive of you. Free citizens have the inalienable right to protect themselves from the criminals while subjects of the Crown do not - why do you prefer to be an easy victim of criminals? Subject of the Crown are prohibited Crown are even prohibited from carrying a pocket knife - now tell us about all the stabbings and the "extremely high violent crime rate, a third world education system, non-existent publicly funded mental healthcare, over-crowded prisons run for profit, a racially biased justice system, and very high rates of poverty" in my former country. And explain why so many people continue to immigrate to the United States both legally and illegally if your baseless and asinine assumptions are accurate? The fact is, the most crime infested area in any country is always a liberal stronghold. Again, why do you believe people should be easy victims of criminals, aside from your need to blame an inanimate object?
I have this pack and like it a lot. It works well in winter because the side straps are long enough to strap snowshoes to it and there is enough main compartment space to fit the winter bags/clothes. I'm able to shed layers and just shove them in the back straps the same way you would shove stuff into a back mesh pocket. 2.5lbs for a 60L pack with a frame at this price is pretty great. I do wish the top pocket fabric would expand out instead of into the main compartment (which is super annoying if the main compartment is packed full) and that there was a bottle holder on both straps.
Joshua Staines Do you find when fully loaded that you can still pull out items from the side pocket (such as a separate water bottle) and return it while hiking?
As is, it seems perfect for long distance backpacking. Ive always felt having gear on the outside of a pack is inviting loss of gear and at the least sloppy looking. If you can't keep the stuff inside you may need a gear shakedown.
@@elscruffomcscruffy8371 2020 version replaced fabric pocket with mesh, and added ability to put it on the face of backpack. Since it didnt' do anything inside anyway, when straps are compressed, and definetly didnt hold water bladder as intended. Also it added one more shoulder strap pocket. And many other minor improvements.
Excellent review Luke, I remember seeing Andrew Skurka introduce this pack a while ago and thinking it looked interesting. It's nice to hear your thoughts on it. Sierra Designs are really trying to innovate, I've seen a lot of unique designs from them recently.
Belatedly, I have just purchased one with an additional bottle/gear pocket on the front straps. I agree totally with your review. The most comfortable pack I've ever had (vs. Gregory/Berghaus/Karrimor and Osprey Talon 44) . I live in Scotland, so I do use a liner!☔🌨
Have it. Love it. From my experience with the pack (with consideration for the frame, pads, and how well it compresses) it really does feel one with my body. I’ve tried on more traditional packs like the Atmos Aether and a “military” style pack from Mardingtop and neither really beats how secure this feels on my back. I don’t miss the traditional style lid or front mesh pocket. For me, it has everything I need and nothing I don’t.
is pack still going strong? I will agree abt comfort but durability is questionable, I see shoulder straps coming off over time. one seam on soft foam or thin nylon isn't enough. any other backpacks even cheap ones got better attachemt points.
Yes, having the ability to stow wet clothing in an external net option is a must for longer term hiking. Also, a more puncture/rip proof bottom needs to happen. The ample belt storage makes up for the cover pocket being small. Nice pack at a fair price.
Andrew Skurka, the designer, recommends using a trash compactor bag inside to keep your gear dry - it's not claimed to be a waterproof pack. Then he stores wet gear inside the pack but outside the compactor bag. It's a tradoff - the outer stuff pocket is convenient, but is prone to snagging and ripping. It's a choice between that and the compression gusset. The idea with this pack is to make the lid so easy to use that you don't miss the stuff pocket.
IMHO, you're spot on, Luke. Sierra Designs is the boldest in new designs, many very well thought out as well as some in need of improvement. My SD gear consists of two down bags, the Mobile Mummy 600/15 and Nitro 800/20 plus one Winter pack, the Ministry 40L. The pack is discontinued, but it was/is cutting edge in design for comfort, function and durability. The Flex Capacitor is innovative in so many regards and I see why you're stoked on it. I also have an Arc'teryx Bora 65L that rocks my world, but if I was on the market for a new pack the FC would be the one I'd jump for.
Cool pack! Not only is it flex capacitor because its size is flexible, but also if you look at the internal Y frame it is shaped like the flex capacitor. Back to the future aside lol, it is a pretty cool pack. Very ergonomic shape. Easy dump style main compartment makes loading and unloading a breeze. I prefer internal frame sheets over stays but they do carry more weight. I would give it a go. Gonna def check out the 2020 version. Hike on!
Look at the shape of the aluminum frame and tell me again that the name has nothing to do with the flux capacitor from Back to the Future... and it's sKurka, not shurka...
Two years ago I bought a pack from Tru-Spec (I don’t remember if it had a name) that was similar to this pack but it looked like a military pack. I’ve enjoyed using it for anything from a weekend trip to nine days. What might surprise you was the cost, at $45 (it was a close out) it was very underpriced. The major differences with the Tru-Spec and this pack is the material, waterproof 600 D (in pixelated camouflage) makes it weight more than this pack (3 lbs 6 oz), the sternum strap wasn’t as adjustable as I would’ve liked (this has been modified), no water bottle pocket on the shoulder straps and there weren’t any waist belt pockets (there are now but that’s me again). It’s still as comfortable to wear today as when it was new.
Looks like they redesigned this pack. 2 waterbottle holders up front, 2 extra attachment points where you suggested them. Not sure about pocket size from the pictures, but I love that Sierra Designs is improving on an already awesome pack.
Heyja, just an idea to save from the trouble of changing the zipper colour tie thing, I had the same problem with the pack I use for school and I solved it by closing the double zippers on the opposite side from the single zipper. In this case the main compartment zippers could be closed on the left side while the small lid compartment zipper always goes to the right side. This way you should open the right compartment more often ^_^
Been trying to find something better and lighter than my 25 y.o. pack w/o luck. Saw SD made packs, saw your review, and just had to try. So far it is the only pack that has fit as well as my old pack, but at right about exactly 1/2 the weight & w/ better features. I stunned this pack isn't in more shops. If this is your pack, it's really obvious. Your review made the difference for me to go ahead and get it & glad I did.
I feel as though this bag is more for the hiker that already has their hiking essentials dialed in and doesn’t have to worry about extra space because they already know what they need to bring
Finally a great review. Really enjoy your videos man. I've used your honest opinion a few times when buying gear and even bring up the same pros and cons when talking to store staff that are essentially trying to sell you something and even they are shocked. Any chance you can do a review on the AARN Natural Balance Pro?
I was between this and Osprey Levity. Then another one. Then yet another one. My brain is fried lol. When picking up a lady, I'm not that selective lol lol (divorced twice). But when it comes to choosing the right backpacking gear, I turn into something else. Finally ordering Flex capacitor. Thanks for the great review.
@@Menkalo that depends on the total volume of all your gear. I think this would work great. The designer of the backpack (Andrew Skurka) uses it for everything from short weekend trips to elk hunting. I've even used it for a road trip. With how much this pack weighs, it's definitely worth it for practically every use. Only people who are looking to go true ultralight would want something smaller/lighter. At that point you're counting ounces/grams.
The Heathen Hiker Thanks for your reply! Looks like my kind of pack. I’m not too worried about being ultralight, but I don’t bring more than I need either. The versatility of this pack seems great. I am slightly worried about people’s comments about the bottom not being reinforced, but I’m sure I’d be careful enough. Unless it wears out from careful/normal usage.
@@theheathenhiker7631 really? is it still strong? when I see the shoulder strap attachments points I fear, I have no confidence in this pack although I like it and it s comfortable. there are reports straps just rip away. not surprising if just one seam sewn directly onto foam or thin nylon
I bought one at end of 2016. I used it a couple times I now use the space arc blast most of time. I found the arc blast is not that comfortable if the weight is over 25 lbs. I should give this pack more chances especially I’m carrying more than 25 Ibs. Good reviews I love your stories
Great review man! I recently found this pack on their website. Very cool pack! I like the Y frame construction and the space it offers off your back for ventilation. Some companies do not take that into consideration. I hate a sweaty back while hiking. Nice padding it looks like and the waterbottle pocket on the shoulder straps is a nice touch and so is the removable bladder pocket. The compression straps could be a little wider and the small red buckles worry me a bit. They dont look like itw nexus or fastex buckles. Its hard to trust other buckles after using them for so long but great overall design, shape and features. A quick pack, go and dump style pack nice! Hike on!
Good idea but I'll wait for the 2.0 version. I attach things to the top, bottom and back of my packs. Without that ability it's a non-starter for me. Those additions would make this a pack I might purchase. I hope Sierra Designs see's this review and makes some additions.
I made a big mesh pocket comment on Instagram and Andrew Skurka replied to and said he just uses a trash compactor bag for all his dry stuff and just put all his wet stuff outside the trash compactor bag ... and that way he doesn't have things hanging outside his pack.. But I do really like this pack.
Hi, I enjoy watching your reviews they are very informative, I also like the camping videos. I'm very interested in getting some Wiggy's equipment. A sleeping bag, vest, boot liners etc. The claims they make sound incredible. I would love to see you do a review on some of their products. Thank you
Seems like an awesome design. While they can't carry as heavy loads and are more expensive, it might be worth checking out the ULA packs if you haven't already. I have the Circuit and love it.
It’s a shame he didn’t clearly show the main point of the pack and exactly how it expands and contracts. Reading the comments, some people didn’t get it.
Was thinking, you can always attach a dry bag or stuff sack to the front of the pack and secure it under the compression straps. I'm a fan of the mesh pocket to stuff wet gear in, but perhaps this might be an option
Organizational pockets are overrated. All your gear is already in neat packs of their own (I assume that's how most people pack their stuff), so just organize the packs down the main chute. Everything you need to get really quickly will be in the waist pockets, top pocket, or right under the main flap. Everything else you need to put outside your pack will be held down by the compression straps, either in the middle at the gusset, or at the sides. And no, you really don't need a large mesh pocket to dry your stuff. But if you insist, you can easily fabricate your own with a laundry mesh bag, elastic band and minimal sewing skills. This thing can carry 60L, which is a lot of space, so honestly, why would you need modifications/upgrades to strap stuff on top of the pack, below the pack, etc? There is good reason why this pack is so versatile and yet only 1.2kg. It is simple, does what it is supposed to do, carries the weight well, and cuts out all the fancy stuff to reduce weight. If you want to simplify your travel and still be able to add a ton of stuff in later on, this pack is for you. If you like pockets and meshes everywhere to organize and hide stuff all over the place, this pack is definitely not it.
How is the flexible capacity on the FC really any different than any other bag with compression straps? I'm in the market and it seems to be the only lightweight pack that has a proper suspension with ability to carry 35lbs or more. That said- wish it had a few more features, but I love the weight, back airflow- price is great too. The Osprey Levity was just too light- string straps, no pouches on the waist strap, etc. The Osprey Exos, similar weight- but can't handle weight. Suspension not great. Osprey Paragon 58 a possibility, good suspension- but a pound more, with really not any more features. Oh- totally agree with your suggestions. As for more colors- dark earth tones... eh. I'd go for bright orange myself. Prefer not to get hunted. :) Question- since the Brain doesn't snug down on top- does stuff jiggle in the top? As that's where I would put little, loose stuff.
When you zoom in for showing feature, the audio lower too much it's hard to hear. Anyway, now I'm waiting if I can try this bag before deciding to buy this, look very interesting
Hi there Luke you mentioned that this is the second most comfortable pack you’ve used. Would you put the Crown2 at third or even lower? I’m looking into a new pack and your in depth review caught my attention. Thanks.
You'll save $2.44 per gram with this pack over a Zpacks Arc Haul. If trying to save money this is one of the best ways to do it! If it needs a pack cover for waterproofing you can offset that weight/cost by trimming and restitching the excess straps on this pack.
I'm wondering if, given the open rucksack design, it would be smart to sub-divide the interior by using various colors & sizes of smaller stuff-sacks? I'm not an expert, by any means, but that was my thought. Maybe a yellow one for fire-starting gear, a red one for food, a green one for extra/spare body clothing, a blue one for extra/spare socks, gloves and balaclava, etc. It seems that would make it easier to find things quickly inside the larger pack body. Maybe you'd already have the food in a sack for hanging out of reach of bears? I think the main problem with this backpack would be small things sliding around and disappearing down into the main pack body.
After a long hesitation, i had this pack on sale here in Europe. The all bag is great, nice construction and great options. Not ultralight, but not heavy in anymeans neither. The option to be able to get from 40 to 60 is nice. As said in the video (excellent video btw) : I think the bottom should defenatly be reinforced, coz as i received mine, i noticed a really small hole on the bottom, almost like what a little sharped knife could have done... (nor a really abbrasive rock...) So i'm not sure about the durability on this pack especially if you're not looking carefully where you put this on the ground. And as we are all hikers, and get tired someday, we are not, all the time looking at where to put our stuff on the ground with softness ^^ The other "con" that bump me out quite quickly, (and maybe it's just me coz i haven't read anything on those reviews i checked) is the belt that... is strangely like... curved and wich push back on the stomach... wich is not a really nice sensation as i feel like something is pressing hard on my belly (and let's be honest, i'm kind of skinny) : So the only solution i found with this, is to rotate one of the Belt Clipper once, making the belt "flat" again, so in doesn't press on the belly anymore... The rest of the pack, i must say, is kind of great and almost... FANTASTIC ! Pockets are great, load transfert with that Y system works impressively well. I'm not sure if i'm gonna keep mine (i have to send it back 1st to get a new one without that bottom hole first) or just stay on my Granite Gear Virga 2 wich is great but lack belt pockets !) Happy Hiking everyone ! Cheers from Belgium (FLAT... belgium...)
Hello Belgian compatriot, I am mountaineering in Carpates, RO. Question: how to transport the tent 2 persons? where to fix it? Do you have idea? Thank you by advance,
Gonna wait 2-ish years until they make your suggested improvements (With a bit of extra weight capacity), and then get it. With those improvements, it would be the ultimate pack.
I'd buy this in a second if it had more stowage compartments, a stiffer or thicker bottom, and more attachment points on the body and bottom piece. That said, it's still a kickass pack.
I'm 6'2" and about 200. Pack fits great.I'm really impressed with it. Sierra Designs has a waist belt size chart on their website. I'd recommend checking your measurements with the chart to be safe
I Think i could like that pack a lot, at least as much as my Old Virga 2 from Granite Gear... I'm strongly looking for that kind of multi-volume backpack and the only thing i do'nt really like here is the top Lid with that zipper instead of a roll-top... HmmMMmmmMMm...... I might consider this one instead of that Vaude Zerum 48+ wich i got eyes on, as that one might get a bit too big on the shorter and ligther trips... where the 40L of the sierra is very good for shorter trips... HmmMMMmMMM Hard choices ^^ Thanks for the review, appreciate the effort and very instructive ! keep up the good Work ! Cheers from Belgium !
@TheOutdoorGearReview: I noticed something: that backpack bottom is just too soft, or fragile! If you can, take and cut up an old tire tread that you can fit across the bottom of that pack, and Hot-Glue it onto the pack-bottom. It'll save against lots of punctures, and tears!
Nice pack without question! Would I buy it probably not! I use my ILBE still ! Marine Corp issue serves me well! Heavier pack ? Yes it is but I’m use to it! I’ve put 35 to 40 lbs in it and gone out for a couple to 3 days! Molle loops are a plus! Now having said all that! Unless they come out with a pack that will make me a hot cup of coffee and make me a sammich I have to stick with my ILBE ..Rugged is the way o roll! Peace Brother!
I have the Coyote 80. Its heavy, super strong. Kelty has great customer service. Its bombproof. I use mine for short winter hikes or family camping when I have to carry a lot of stuff. I've carried over 50lbs without troubles except for my knees. lol. Not for thru hiking. I use zpacks arc haul for ultra light hiking.
Hey Luke, I know you more than likely get more than enough requests for reviews, but wondering if you could review the Outdoor Vitals backpacks they are a new company with good prices, don't have allot of money to buy top of the line and in looking at them they have a ton of extras that would come in very handy. Thanks Luke and God Bless.
Hey man, simply question: What camera are you using? I'm happy with my Pixel 2 in general but the AF annoys me. Whatever you use seems locked on. Thanks!
Spot on as always, Luke. Thanks. Definitely agree on adding some loops/straps to secure things like a sleep system or small tent to the outside. What's your opinion on Eberlestock gear? I'm torn on the weight/durability question with theirs.
Awesome Luke, I love the water bottle holder on the strap, in fact I'm looking for one for my day pack, do you know of anyone that makes one that I can attach?
Skurka is a smart designer, but I'm not convinced by the tradeoffs with this concept. The Y suspension system with the DAC poles is interesting, giving you a bit of flex at the shoulders. And the scapular pads do seem to offer decent venting. But the gusset expansion system is more questionable. With a typical UL rolltop combined with side compression you have almost as much flexibility with the volume and you also get a very useful front pocket. But you lose the top lid and the fixed height. With the Flex, you get a fixed height, which can improve the carry a bit when it's fully loaded. But the top pocket is no substitute for a good front pocket, and in my experience curved zips are decidedly failure prone, while the roll top is pretty much failproof. I design my own packs, and am interested in playing with the suspension system. But I think I'd replace the zip lid with a more conventional rolltop and front pocket.
I have the pack and it is my favorite along side the MLD prophet in dcf. I find I really like the zip ease of getting in more than rolling but also wish they would have just made all the zips waterproof. The packs not, but it would keep the moisture out a bit longer, the zip cover doesnt do much. For any outside items I find I just use the straps to hold items in place if they need to be outside, like a sitpad. In very inclement weather nothing on the outside is going to dry anyway and those items would be in a separate bag on the inside or reverse and have all the other items in a contractor bag. If its not a concept you're used to I can totally see how the trade-offs would be a point of skepticism. The more I use it, and others, the more it becomes my go to.
@@nojaysimpson Thanks Brian - very interesting. I'm still playing with prototypes, and am coming round to your way of thinking. I've been reading Andrew's blog about the design choices, and they do make sense. On long distance hikes, you really do need a flexible capacity, as you may need to carry winter gear at times, and anything up to 10 days of food. Or you may be 1 day out from resupply with warm weather gear. With roll-tops, you handle this by extending the height, which affects the balance and makes it awkward when scrambling over blowdowns etc. Or you can keep the height the same and use a gusset to compress the body, as with this pack. I feel that the gusset is a better solution to adapting the capacity. But you lose the mesh stuff pocket. The solution to that would be a better sized pocket in the lid, and some kind of quick access to the main body. But then you have the issue of protecting the zip. Waterproof zips don't last as long, but the flap looks problematic. Tradeoffs, tradeoffs...
I would like to try out this (now discontinued) pack, but to me, I don't think the center gusset has any advantages over a more standard side compression system and also prevents incusion of a front pocket, which are highly convenient. I think side compression combined with bottom compression is a better solution. Plus bottom compression can double as a way to strap items such as a sleeping pad to the bottom of the pack. Bottom compression also has the advantage of shifting the load up higher on your shoulders when you are not carrying much volume.
Interesting. Due to the lack of features on the pack I would expect it to weigh closer to 2 pounds. The lack of external mesh or bungee grid and the lack of attachment points on the top and bottom are problematic. Would it kill them to add a whistle? For me, I'd pass. The only redeeming feature is the expandability but I'd rather have two packs.
@TheOutdoorGearReview I've seen you review the Crown2 and now this pack. I have been in a HUGE debate about which to get. Both are the same price, roughly. Frame sheet vs Y frame. Lid vs Removable "brain"/rolltop. What would your opinion be for 25-40lb weight? Or disregarding weight limits, which pack would you choose? Thanks!
I'm facing the same dilemma. I really like what I've seen of each pack. Don't know which one to get. Both are available locally where I am in Colorado, so the smartest thing to do is probably to just go try each pack on in person and see if one stands out.
Lack of an exterior mesh pocket is a showstopper for me. I don't get the argument that this is "innovative". Seems like a regular pack with the compression straps on center as opposed to the sides. Only difference is there's no room for a mesh pocket with the cinch straps in the way! Good marketing though...
Agreed, generally. The horizontal strapping has been on the back face of Granite Gear packs for a long time. Infact, that's why I love some of their packs so much - the ability to truly secure things instead of swinging attachments.
Those aren’t merely horizontal compression straps (just two are). I wished he’d clearly demonstrated the main point of the pack: with the other four straps and the gusseted fabric down the center, the whole size of the pack changes. There are pics out there that better show it cinched down to a tight 40L pack and expanded out to a bear can ready multi-day 60L. He really didn’t show how that works.
Okay. Yes, when the review began I was expecting the pack to be of the kind you describe but wasn't really given that impression during it. I'm curious now, but not convinced though that any pack which has the static frame length / rigidity to be able to carry 60ltrs, can truly be cinched down though. I know what pack makers are getting at, but all cinching can do is (currently) is reign in loose unused material from sagging down. Granite Gear packs have the abiility to cinch the various straps right down to keep unused material very close to the frame but doing so never really looks neat and tidy and the frame height is the frame height.
....to add, perhaps the only way to truly make a pack genuinally transform in size from day pack to expedition size is some form of telescopic frame (walking pole, style), combined with that cinching of material. Complexity adds weight though, a basic frame weight whatever scale the pack is reduced to or expanded to.
every review of every pack you've ever had you said the lid except for that backpack about a month ago where you called it a brain. Every review I saw of that pack called it a brain. Were you requested by the company to call it a brain? Nothing else explains why every UA-camr called it a brain instead of a lid
The term 'brain' is fairly common terminology within the backpacking world and if I remember correctly, the company referenced this term on their web site and I mentioned it because of that fact in the review. Not requested by the company to say anything. - Luke

Ordered one for my son for his birthday, loved it so much I got myself the bigger one. Great review. Cheers
I have this pack and like it a lot. It works well in winter because the side straps are long enough to strap snowshoes to it and there is enough main compartment space to fit the winter bags/clothes. I'm able to shed layers and just shove them in the back straps the same way you would shove stuff into a back mesh pocket. 2.5lbs for a 60L pack with a frame at this price is pretty great. I do wish the top pocket fabric would expand out instead of into the main compartment (which is super annoying if the main compartment is packed full) and that there was a bottle holder on both straps.

I prefer internal frame sheets over stays but they do carry more weight. I would give it a go. Gonna def check out the 2020 version. Hike on!
Look at the shape of the aluminum frame and tell me again that the name has nothing to do with the flux capacitor from Back to the Future... and it's sKurka, not shurka...
Two years ago I bought a pack from Tru-Spec (I don’t remember if it had a name) that was similar to this pack but it looked like a military pack. I’ve enjoyed using it for anything from a weekend trip to nine days. What might surprise you was the cost, at $45 (it was a close out) it was very underpriced. The major differences with the Tru-Spec and this pack is the material, waterproof 600 D (in pixelated camouflage) makes it weight more than this pack (3 lbs 6 oz), the sternum strap wasn’t as adjustable as I would’ve liked (this has been modified), no water bottle pocket on the shoulder straps and there weren’t any waist belt pockets (there are now but that’s me again). It’s still as comfortable to wear today as when it was new.
Looks like they redesigned this pack. 2 waterbottle holders up front, 2 extra attachment points where you suggested them. Not sure about pocket size from the pictures, but I love that Sierra Designs is improving on an already awesome pack.
They aren't 'attachment points'. They are to stow the water tube of a bladder system away on either shoulder strap.
Heyja, just an idea to save from the trouble of changing the zipper colour tie thing, I had the same problem with the pack I use for school and I solved it by closing the double zippers on the opposite side from the single zipper. In this case the main compartment zippers could be closed on the left side while the small lid compartment zipper always goes to the right side. This way you should open the right compartment more often ^_^
Been trying to find something better and lighter than my 25 y.o. pack w/o luck. Saw SD made packs, saw your review, and just had to try. So far it is the only pack that has fit as well as my old pack, but at right about exactly 1/2 the weight & w/ better features. I stunned this pack isn't in more shops. If this is your pack, it's really obvious. Your review made the difference for me to go ahead and get it & glad I did.
I have that pack for over a year now. I would agree its not perfect but carries better than my ULA by far.
Great review Luke, thank you.
Another awesome review man. Very detailed keep it up brother! Stay safe!
Very pleased with mine.
I feel as though this bag is more for the hiker that already has their hiking essentials dialed in and doesn’t have to worry about extra space because they already know what they need to bring
Great review! Thanks for sharing :)
Finally a great review. Really enjoy your videos man. I've used your honest opinion a few times when buying gear and even bring up the same pros and cons when talking to store staff that are essentially trying to sell you something and even they are shocked.
Any chance you can do a review on the AARN Natural Balance Pro?
I was between this and Osprey Levity. Then another one. Then yet another one. My brain is fried lol. When picking up a lady, I'm not that selective lol lol (divorced twice). But when it comes to choosing the right backpacking gear, I turn into something else. Finally ordering Flex capacitor. Thanks for the great review.
I've got one and I love it! Love the versatility!
I’m looking for a bag I can use for both weekend overnighters/traveling and week long camping. Would you recommend this one?
@@Menkalo that depends on the total volume of all your gear. I think this would work great. The designer of the backpack (Andrew Skurka) uses it for everything from short weekend trips to elk hunting. I've even used it for a road trip. With how much this pack weighs, it's definitely worth it for practically every use. Only people who are looking to go true ultralight would want something smaller/lighter. At that point you're counting ounces/grams.
The Heathen Hiker Thanks for your reply! Looks like my kind of pack. I’m not too worried about being ultralight, but I don’t bring more than I need either. The versatility of this pack seems great. I am slightly worried about people’s comments about the bottom not being reinforced, but I’m sure I’d be careful enough. Unless it wears out from careful/normal usage.
@@Menkalo my guess is that they're rough on their gear. It seems just as durable as any other pack I've owned.
@@theheathenhiker7631 really?
is it still strong?
when I see the shoulder strap attachments points I fear, I have no confidence in this pack although I like it and it s comfortable.
there are reports straps just rip away. not surprising if just one seam sewn directly onto foam or thin nylon
I bought one at end of 2016. I used it a couple times I now use the space arc blast most of time. I found the arc blast is not that comfortable if the weight is over 25 lbs. I should give this pack more chances especially I’m carrying more than 25 Ibs. Good reviews I love your stories
Thanks for the review I'm impressed
Great review man! I recently found this pack on their website. Very cool pack! I like the Y frame construction and the space it offers off your back for ventilation. Some companies do not take that into consideration. I hate a sweaty back while hiking. Nice padding it looks like and the waterbottle pocket on the shoulder straps is a nice touch and so is the removable bladder pocket. The compression straps could be a little wider and the small red buckles worry me a bit. They dont look like itw nexus or fastex buckles. Its hard to trust other buckles after using them for so long but great overall design, shape and features. A quick pack, go and dump style pack nice! Hike on!
Good idea but I'll wait for the 2.0 version. I attach things to the top, bottom and back of my packs. Without that ability it's a non-starter for me. Those additions would make this a pack I might purchase. I hope Sierra Designs see's this review and makes some additions.
I made a big mesh pocket comment on Instagram and Andrew Skurka replied to and said he just uses a trash compactor bag for all his dry stuff and just put all his wet stuff outside the trash compactor bag ... and that way he doesn't have things hanging outside his pack.. But I do really like this pack.
Hey Luke. Great review! It would be awesome to see you review the Karrimor SF Predator Patrol 45 PLCE Backpack.
No, no! YOU are the world - famous hiker and backpacker! 😀
Thank you Moggridge! How are you doing? - Luke
TheOutdoorGearReview Fine thanks, Luke, and I hope you and your family are too. Always enjoy the videos. 👍
Hi, I enjoy watching your reviews they are very informative, I also like the camping videos. I'm very interested in getting some Wiggy's equipment. A sleeping bag, vest, boot liners etc. The claims they make sound incredible. I would love to see you do a review on some of their products. Thank you
Seems like an awesome design. While they can't carry as heavy loads and are more expensive, it might be worth checking out the ULA packs if you haven't already. I have the Circuit and love it.
Hey Luke, Great Review!!! maybe you should do a Vs. episode of the Flex Capacitor and the Granite Gear Crown 2 60
That would be a great comparison as they are two of the only packs in this flex category
That would be a great comparison as they are two of the only packs in this flex category
Have thought about designing and making your own pack ?
It’s a shame he didn’t clearly show the main point of the pack and exactly how it expands and contracts. Reading the comments, some people didn’t get it.
Good review thanks!
I think it's gonna be my next pack
Goodun Luke. Nice pack.
Nice vid, good looking pack!
I like the looks of this pack
Kind of reminds me of my old north face skareb 55 a little. I like it.
Great Scot Like that front bottle holder
If they did the improvements. I would really consider on buying this backpack
They have improved it, but only a little. Two shoulder pockets and a removable net that holds your hydration on the inside to hanging on the outside
Was thinking, you can always attach a dry bag or stuff sack to the front of the pack and secure it under the compression straps. I'm a fan of the mesh pocket to stuff wet gear in, but perhaps this might be an option
Organizational pockets are overrated. All your gear is already in neat packs of their own (I assume that's how most people pack their stuff), so just organize the packs down the main chute. Everything you need to get really quickly will be in the waist pockets, top pocket, or right under the main flap. Everything else you need to put outside your pack will be held down by the compression straps, either in the middle at the gusset, or at the sides. And no, you really don't need a large mesh pocket to dry your stuff. But if you insist, you can easily fabricate your own with a laundry mesh bag, elastic band and minimal sewing skills. This thing can carry 60L, which is a lot of space, so honestly, why would you need modifications/upgrades to strap stuff on top of the pack, below the pack, etc? There is good reason why this pack is so versatile and yet only 1.2kg. It is simple, does what it is supposed to do, carries the weight well, and cuts out all the fancy stuff to reduce weight. If you want to simplify your travel and still be able to add a ton of stuff in later on, this pack is for you. If you like pockets and meshes everywhere to organize and hide stuff all over the place, this pack is definitely not it.
How is the flexible capacity on the FC really any different than any other bag with compression straps? I'm in the market and it seems to be the only lightweight pack that has a proper suspension with ability to carry 35lbs or more. That said- wish it had a few more features, but I love the weight, back airflow- price is great too. The Osprey Levity was just too light- string straps, no pouches on the waist strap, etc. The Osprey Exos, similar weight- but can't handle weight. Suspension not great. Osprey Paragon 58 a possibility, good suspension- but a pound more, with really not any more features. Oh- totally agree with your suggestions. As for more colors- dark earth tones... eh. I'd go for bright orange myself. Prefer not to get hunted. :) Question- since the Brain doesn't snug down on top- does stuff jiggle in the top? As that's where I would put little, loose stuff.
When you zoom in for showing feature, the audio lower too much it's hard to hear.
Anyway, now I'm waiting if I can try this bag before deciding to buy this, look very interesting
Thanks for pointing that out; I didn't notice it on my system or during editing. - Luke
Hi there Luke you mentioned that this is the second most comfortable pack you’ve used. Would you put the Crown2 at third or even lower? I’m looking into a new pack and your in depth review caught my attention. Thanks.
You'll save $2.44 per gram with this pack over a Zpacks Arc Haul. If trying to save money this is one of the best ways to do it! If it needs a pack cover for waterproofing you can offset that weight/cost by trimming and restitching the excess straps on this pack.
Graham Floyd Gosh, a rain cover weights close to nothing...
I'm wondering if, given the open rucksack design, it would be smart to sub-divide the interior by using various colors & sizes of smaller stuff-sacks? I'm not an expert, by any means, but that was my thought. Maybe a yellow one for fire-starting gear, a red one for food, a green one for extra/spare body clothing, a blue one for extra/spare socks, gloves and balaclava, etc. It seems that would make it easier to find things quickly inside the larger pack body. Maybe you'd already have the food in a sack for hanging out of reach of bears? I think the main problem with this backpack would be small things sliding around and disappearing down into the main pack body.

Some people buy different textured bags to organize. That way you’d be able to feel instead of having to look through everything.
After a long hesitation, i had this pack on sale here in Europe.
The all bag is great, nice construction and great options.
Not ultralight, but not heavy in anymeans neither.
The option to be able to get from 40 to 60 is nice.
As said in the video (excellent video btw) :
I think the bottom should defenatly be reinforced, coz as i received mine, i noticed a really small hole on the bottom, almost like what a little sharped knife could have done... (nor a really abbrasive rock...)
So i'm not sure about the durability on this pack especially if you're not looking carefully where you put this on the ground. And as we are all hikers, and get tired someday, we are not, all the time looking at where to put our stuff on the ground with softness ^^
The other "con" that bump me out quite quickly, (and maybe it's just me coz i haven't read anything on those reviews i checked) is the belt that... is strangely like... curved and wich push back on the stomach... wich is not a really nice sensation as i feel like something is pressing hard on my belly (and let's be honest, i'm kind of skinny) : So the only solution i found with this, is to rotate one of the Belt Clipper once, making the belt "flat" again, so in doesn't press on the belly anymore...
The rest of the pack, i must say, is kind of great and almost... FANTASTIC !
Pockets are great, load transfert with that Y system works impressively well.
I'm not sure if i'm gonna keep mine (i have to send it back 1st to get a new one without that bottom hole first) or just stay on my Granite Gear Virga 2 wich is great but lack belt pockets !)
Happy Hiking everyone !
Cheers from Belgium (FLAT... belgium...)
Hello Belgian compatriot,
I am mountaineering in Carpates, RO.
Question: how to transport the tent 2 persons? where to fix it?
Do you have idea?
Thank you by advance,
Gonna wait 2-ish years until they make your suggested improvements (With a bit of extra weight capacity), and then get it. With those improvements, it would be the ultimate pack.
I'd buy this in a second if it had more stowage compartments, a stiffer or thicker bottom, and more attachment points on the body and bottom piece. That said, it's still a kickass pack.
Excellent review I like the back padding on this one. Would it fit good on the bigger guys 6'1 220?
I'm 6'2" and about 200. Pack fits great.I'm really impressed with it. Sierra Designs has a waist belt size chart on their website. I'd recommend checking your measurements with the chart to be safe
I Think i could like that pack a lot, at least as much as my Old Virga 2 from Granite Gear...
I'm strongly looking for that kind of multi-volume backpack and the only thing i do'nt really like here is the top Lid with that zipper instead of a roll-top...
HmmMMmmmMMm......
I might consider this one instead of that Vaude Zerum 48+ wich i got eyes on, as that one might get a bit too big on the shorter and ligther trips... where the 40L of the sierra is very good for shorter trips...
HmmMMMmMMM
Hard choices ^^
Thanks for the review, appreciate the effort and very instructive !
keep up the good Work !
Cheers from Belgium !
The lid is fine just my the zips to the left. The top pocket is on the right.
@TheOutdoorGearReview:
I noticed something: that backpack bottom is just too soft, or fragile! If you can, take and cut up an old tire tread that you can fit across the bottom of that pack, and Hot-Glue it onto the pack-bottom. It'll save against lots of punctures, and tears!
Let's hope they upgrade the bottom to a tougher, yet lighter natural to maintain the ultralight feel
Nice pack without question! Would I buy it probably not! I use my ILBE still ! Marine Corp issue serves me well! Heavier pack ? Yes it is but I’m use to it! I’ve put 35 to 40 lbs in it and gone out for a couple to 3 days! Molle loops are a plus! Now having said all that! Unless they come out with a pack that will make me a hot cup of coffee and make me a sammich I have to stick with my ILBE ..Rugged is the way o roll! Peace Brother!
Hey Luke have you/can you review some of the kelty line of bags like the coyote 80/65 or the Revol 65?
I have the Coyote 80. Its heavy, super strong. Kelty has great customer service. Its bombproof. I use mine for short winter hikes or family camping when I have to carry a lot of stuff. I've carried over 50lbs without troubles except for my knees. lol. Not for thru hiking. I use zpacks arc haul for ultra light hiking.
Can you do a video on what you keep in your pack for summer overnight
Hey Luke, I know you more than likely get more than enough requests for reviews, but wondering if you could review the Outdoor Vitals backpacks they are a new company with good prices, don't have allot of money to buy top of the line and in looking at them they have a ton of extras that would come in very handy.
Thanks Luke and God Bless.
Hey man, simply question: What camera are you using? I'm happy with my Pixel 2 in general but the AF annoys me. Whatever you use seems locked on. Thanks!
Spot on as always, Luke. Thanks. Definitely agree on adding some loops/straps to secure things like a sleep system or small tent to the outside.
What's your opinion on Eberlestock gear? I'm torn on the weight/durability question with theirs.
please do a review of the new Osprey levity asap. very lightweight pack but not as durable. I want to know your thoughts.
Awesome Luke, I love the water bottle holder on the strap, in fact I'm looking for one for my day pack, do you know of anyone that makes one that I can attach?
Z-packs has these and other add on's as well, not very cheap but very light and high quality.
Hey luke if you are going to choose a backpack for a bug out scenario what you are going to choose?
Skurka is a smart designer, but I'm not convinced by the tradeoffs with this concept. The Y suspension system with the DAC poles is interesting, giving you a bit of flex at the shoulders. And the scapular pads do seem to offer decent venting. But the gusset expansion system is more questionable.
With a typical UL rolltop combined with side compression you have almost as much flexibility with the volume and you also get a very useful front pocket. But you lose the top lid and the fixed height.
With the Flex, you get a fixed height, which can improve the carry a bit when it's fully loaded. But the top pocket is no substitute for a good front pocket, and in my experience curved zips are decidedly failure prone, while the roll top is pretty much failproof.
I design my own packs, and am interested in playing with the suspension system. But I think I'd replace the zip lid with a more conventional rolltop and front pocket.
I have the pack and it is my favorite along side the MLD prophet in dcf. I find I really like the zip ease of getting in more than rolling but also wish they would have just made all the zips waterproof. The packs not, but it would keep the moisture out a bit longer, the zip cover doesnt do much. For any outside items I find I just use the straps to hold items in place if they need to be outside, like a sitpad. In very inclement weather nothing on the outside is going to dry anyway and those items would be in a separate bag on the inside or reverse and have all the other items in a contractor bag. If its not a concept you're used to I can totally see how the trade-offs would be a point of skepticism. The more I use it, and others, the more it becomes my go to.
@@nojaysimpson Thanks Brian - very interesting. I'm still playing with prototypes, and am coming round to your way of thinking. I've been reading Andrew's blog about the design choices, and they do make sense. On long distance hikes, you really do need a flexible capacity, as you may need to carry winter gear at times, and anything up to 10 days of food. Or you may be 1 day out from resupply with warm weather gear. With roll-tops, you handle this by extending the height, which affects the balance and makes it awkward when scrambling over blowdowns etc. Or you can keep the height the same and use a gusset to compress the body, as with this pack. I feel that the gusset is a better solution to adapting the capacity. But you lose the mesh stuff pocket. The solution to that would be a better sized pocket in the lid, and some kind of quick access to the main body. But then you have the issue of protecting the zip. Waterproof zips don't last as long, but the flap looks problematic. Tradeoffs, tradeoffs...
I would like to try out this (now discontinued) pack, but to me, I don't think the center gusset has any advantages over a more standard side compression system and also prevents incusion of a front pocket, which are highly convenient. I think side compression combined with bottom compression is a better solution. Plus bottom compression can double as a way to strap items such as a sleeping pad to the bottom of the pack. Bottom compression also has the advantage of shifting the load up higher on your shoulders when you are not carrying much volume.
Interesting. Due to the lack of features on the pack I would expect it to weigh closer to 2 pounds. The lack of external mesh or bungee grid and the lack of attachment points on the top and bottom are problematic. Would it kill them to add a whistle? For me, I'd pass. The only redeeming feature is the expandability but I'd rather have two packs.
Almost innovation, the Karrimor SF Sabre 60-100 and SF Predator 80-130 are at least 25 years old.
Hi mate
Looking to buy one … my torso measured 20 inches. I am between sizes as both s/m and m/l would fit. Which one should I choose please? Ta
Luke - I want to see you review a Mystery Ranch pack - one of the tri-zip models. That is innovative. I recommend the Ravine.
Are you sure your name ain't Steve-O I'm just teasing you Luke Happy Valentine's Day good review
@TheOutdoorGearReview
I've seen you review the Crown2 and now this pack. I have been in a HUGE debate about which to get.
Both are the same price, roughly.
Frame sheet vs Y frame.
Lid vs Removable "brain"/rolltop.
What would your opinion be for 25-40lb weight?
Or disregarding weight limits, which pack would you choose?
Thanks!
The Outdoor Hooligan Which one did you get?
I'm facing the same dilemma. I really like what I've seen of each pack. Don't know which one to get. Both are available locally where I am in Colorado, so the smartest thing to do is probably to just go try each pack on in person and see if one stands out.
If atmos 50 ag is your number 1 backpack. Will it be your number 2 ?
Should I get this or the ODV shadow light?
Hey Luke, Off Topic but have you ever had a chance to review The Fleece Woobie made by Tactical Tailor?
I haven't but I have been meaning to get that in. - Luke
Nice ive had my eye on it but theres nothing i can find on it..Can't wait Strength and honor brother
Any thoughts on this compared to the Granite Gear Crown 60 ???
No large nylon pocket on the back
My first thought is it reminds me of an lbe only civilian version and much lighter LOL.
Between Sierra Designs Flex Capacitor and Granite gear crown 2 60L.. Which 1 is more comfortable on the shoulder strap hardness and hip belt
My preference would be the Flex Capacitor.
- Luke
shoutout to Skurka!
I like it!!!!
Seeing all of those excess straps just hanging bugs me.
Dig it
a person can sew on as many add ons as they like.
No capacitor inside? Just joking...
Btw I know you are not Chinese but I still wish you the best for the coming year of dog :)
A simple method for removing and installing the frame of this backpack.
The "key movement": ua-cam.com/video/i6O3esf9WF0/v-deo.html
200$ for a pack luke jeeeeeeez thats a little much
$100-200 is a pretty standard for lower range good backpacks. $200-300 is expensive, but on the top notch quality side.
Can anyone say backpackgasm?
Please, flex capacitor or atmos 50 ag ?
Two great packs; I would go with the AG! - Luke
Thank's Luke...
"Shurka" lol
Andrew "shurka ", never heard of her . 😂
shoulder strap stitching is a joke here..
Lack of an exterior mesh pocket is a showstopper for me.
I don't get the argument that this is "innovative". Seems like a regular pack with the compression straps on center as opposed to the sides. Only difference is there's no room for a mesh pocket with the cinch straps in the way! Good marketing though...
Agreed, generally. The horizontal strapping has been on the back face of Granite Gear packs for a long time. Infact, that's why I love some of their packs so much - the ability to truly secure things instead of swinging attachments.
Those aren’t merely horizontal compression straps (just two are). I wished he’d clearly demonstrated the main point of the pack: with the other four straps and the gusseted fabric down the center, the whole size of the pack changes. There are pics out there that better show it cinched down to a tight 40L pack and expanded out to a bear can ready multi-day 60L. He really didn’t show how that works.
Okay. Yes, when the review began I was expecting the pack to be of the kind you describe but wasn't really given that impression during it. I'm curious now, but not convinced though that any pack which has the static frame length / rigidity to be able to carry 60ltrs, can truly be cinched down though. I know what pack makers are getting at, but all cinching can do is (currently) is reign in loose unused material from sagging down. Granite Gear packs have the abiility to cinch the various straps right down to keep unused material very close to the frame but doing so never really looks neat and tidy and the frame height is the frame height.
....to add, perhaps the only way to truly make a pack genuinally transform in size from day pack to expedition size is some form of telescopic frame (walking pole, style), combined with that cinching of material. Complexity adds weight though, a basic frame weight whatever scale the pack is reduced to or expanded to.
bereantrb ok...gussets? I still don't see added functionality. My Osprey pack can be cinched down flat.
every review of every pack you've ever had you said the lid except for that backpack about a month ago where you called it a brain. Every review I saw of that pack called it a brain. Were you requested by the company to call it a brain? Nothing else explains why every UA-camr called it a brain instead of a lid
The term 'brain' is fairly common terminology within the backpacking world and if I remember correctly, the company referenced this term on their web site and I mentioned it because of that fact in the review. Not requested by the company to say anything.
- Luke
Brain usually refers to a removable/ adjustable top.
