Aegismax Ultra-light: Mummy vs Rectangular Down Sleeping Bags
Вставка
- Опубліковано 9 чер 2018
- I review and compare the Aegismax Ultra-Light large size mummy shape vs. rectangular shape down sleeping bags. There are some interesting differences. One expects a mummy shape to be tighter but this is not the case. The rectangular bag also has slightly higher fill weight.
I failed to mention that the rectangular version also has a cinch cord with cord lock at the top opening, so it can be closed close to the neck to retain heat. Also, both models come with the white bag seen at the beginning of the video for storing the bag at home to keep the loft up on the down.
I showed supplementing the bag with one of my Black Diamond quilts. See Frank Bush's review of the mummy version supplemented by a liner plus SOL bivvy. • Aegismax, SOL escape b...
Another post-review consideration - in theory the rectangular version might be a touch cooler at the feet due to the bottom zipper, compared to the sewn end of the mummy style. Just not sure if it would be significant. - Спорт
Thanks for the review. I think it's one of the best, most thorough, I've come across.
Thanks. If you thought THAT was thorough and you are interested in a larger daypack (Osprey vs. Gregory) then check out this more recent review of mine...ua-cam.com/video/qw0GUFexci4/v-deo.html
Thank you for the video. I was leaning to the square one for a super light summer bag. But now I'm thinking the mummy might suit me better. Thank you for hopping in the bags and moving around
Thanks for watching. I'm glad the review helped you decide what'll work best for you. If you camp in winter, these bags make very toasty liners too! I unzip it down to my knees and use it like a quilt over me inside my winter bag.
Love the accuracy you provide. I was trying to decide between the mummy and the rectangular and you gave me exactly what I needed.
Thanks, Craig. I'm glad the review helped you choose between the two.
Thankyou for that , I was struggling to decide which to buy and this was a great help 😁
I'm glad it was helpful!
Thank you for nice information
You're welcome!
Thank you Richard can two rectangular bags be zipped together thanks
I had the same idea of using a second lightweight bag and perhaps a bag liner as well. I could then add or subtract layers as needed. Have you tried the two bag system?
I'm a fan of layering for multiple circumstances, including trips where night temperatures can vary over the duration of the trip, and also to supplement the warmth of another bag for very cold weather. When using the rectangular Aegismax this way inside another bag, I zipped it way down to leave just a footbox and used the rest as a throw just on top since I was on a good pad. It added a nice amount of warmth. The rather thin down on this bag compresses underneath you so all insulation is lost there. So in a hammock it can be zipped again into footbox mode and bunched as a throw on top (adding more loft) while using an underquilt (like the one at the end of my video). I also own an Alps Mountaineering Razor which has been good for summer camping and as a liner, but it's not as compact and light as the Aegismax. See my top description for a link to someone using the Aegismax with a bivvy.
Hi! Thanks for taking the time to make a video about the illusive rectangular bag :0) I know you no longer have the mummy bag, but do you recall much about the difference in size when compressed in their stuff-sacks? I'm assuming the rectangular was a bit bigger? Would it be possible to post it's compressed minimum measurements, or a picture/video of the rectangular one next to some sort of size reference? No worries if not, the info from your video has been quite helpful already!
Thanks for watching and commenting. Yes, the mummy style seems to get all the attention, but I really like the rectangular one for a number of reasons. You might be thinking the rectangular is bigger due to slightly more down feather content? I would say there will be no meaningful difference between the two in terms of compressed size. I bet they even come with the same compression sack, which is about the size of a 1 liter Nalgene bottle. Both are light and very compact. Buy the one you think will work best for you. As I've mentioned in other replies, I'm glad we kept the rectangular.
Hi, I really like your video. Did you field test the second sleeping bag ? How is the comfort temperature?
Thanks for watching. I kept only the rectangular version so I did not field test the mummy style. I will say they would be nearly identical in terms of warmth and are also affected by other circumstances, such as using a decent sleeping pad on the ground or under-quilt for hammocks, as well as layering a little bit with clothing. I'm a cold sleeper so I would use this as a primary bag if low temps would remain at or above 55 F (12 C). There are many reviews of the mummy style out there and they might offer their own opinions too. I find that sleeping warmth really varies from person to person, and maybe with age as well.
PaoloFrancesco99 Thank you！Helps a lot
Hi there, may I ask how tall you are? Thanks you. Des
Sure, you may ask :). So as not to share my specific specs, I'll tell you that I'm a touch under 6 ft (183 cm).
+PaoloFrancesco99 Thank you
Useful video! I am thinking of buying the rectangular. I can't sleep in a mummy bag. I sleep with one knee bended. In a 85cm rectangular bag that works but slimmer bags are too restrictive. The rectangular aegismax could be opened halfway to use as a quilt probably?
Apologies for this late reply. Absolutely, bags like the rectangular Aegismax that open all the way make excellent quilts. I leave a short length at the bottom zippered in order to form a foot box. This way it stays put and doesn;t get kicked to the side. I find the Aegismax to be very comfortable against my skin as well. When hammocking with an underquilt, I really enjoy using the Aegismax as a top quilt. And I also enjoy using it as a liner to supplement my cold weather bags. Very cozy.
Great comparison, so you think for a bigger guy that the mummy actually has more room across the arms and chest?
Thanks, Sean. There's no doubt the mummy style in Large 200 x 86 cm is roomier than the rectangular one which states 200 x 80 cm. And you can kind of see it in my video. Check out the linked video in my description since that guy is bigger than I am, and I think there's another review about the mummy by a bigger guy who likes it for the room it has.
Thank for this interesting review !! The material bag seem to be a little bit noisy..
Thanks for watching and commenting. Regarding noise, I just performed a simple test, moving the Aegismax against itself and a couple of other sleeping bags against themselves as well. The Aegismax seems no noisier than the others. It could be that the simple microphone on my smartphone picked up the high pitches more.
@@PaoloFrancesco99 thanks a lot for your answer !! 😊 May I ask you one last question, is the inside material confortable ? I mean, you know, the feeling sometimes of pasting your skin ?
@@nouvelarrivant Good question. I know what you mean. The material is comfortable but, similar to other poly-lined bags, might feel sticky in warm weather. Leaving the zipper open could help. I kept the rectangular version so I could also open the bottom or just use it like a blanket to keep a little cooler. In cooler weather the bag will be comfortable and not sticky feeling. Another bag I use in summer is Alps Mountaineering Razor. It is lined with a thin fleece that does not feel sticky even on a warmer night. It's not quite as light or compact.
@@PaoloFrancesco99 thanks a lot for your answer !! I subscribe to your channel 😉 have a nice day !
Hi. Usefull comparison.
Is it possible to attach two rectangular bags to each other with zippers? To make a big bag for two people...
I checked Amazon where I bought the bag because someone asked the same question there too. The seller replied that it is NOT possible to zip two together.
@@PaoloFrancesco99 thanks a lot for your answer
I was surfing ebay and I saw a picture of 2 rectangular nature hike rectangular bags zipped together. So actually yes you can. www.ebay.co.uk/itm/Naturehike-Ultralight-Goose-Envelope-Sleeping-Bag-Waterproof-Camping-Hiking-Warm/133285510607?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D20131003132420%26meid%3Dcb4199fa1d9444a0a32701176e2d9974%26pid%3D100005%26rk%3D4%26rkt%3D12%26mehot%3Dpf%26sd%3D184327101386%26itm%3D133285510607%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebWithBBEV1Filter%26brand%3DNaturehike&_trksid=p2047675.c100005.m1851
@Max Chambers - Thanks for sharing that link. I see that NatureHike version in the UK does mate together as you say. I think the bag in my review is slightly different. The shape tapers slightly at the foot end, so I'm not sure the shape of the Aegismax allows two to join together. Maybe so.
Thanks for the review! What about the smell of the bags?
Have a nice day! :)
Thanks for watching. The bag does smell of the feathers when you first get it and this fades over time. Now I've used the bag a bunch of times and I'm really glad I kept the rectangular version.
Hi Paolo - Have only just found your review, as interested in getting the rectangular Aegismax bag. Not many reviews compared to the mummy.
Thanks for a very helpful comparison of the two bags. Was surprised you didn't comment on one of the obvious main differences - horizontal (mummy) vs vertical (rectangular) baffles. Did that impact how warm you found them both in real world testing ?
Was wondering (2 years after posting your comparison) which bag you had found the most useful?
How durable did they prove to be?
And whether with hindsight you would purchase either of them again?
Sorry for the all the questions, but have to make a decision soon.
Many thanks, and greetings from across the pond....
Greetings, Sir Muddy Duck. I kept only the rectangular version so I did not compare warmth in the field, but I would venture to say there is negligible difference. I chose the rectangular because: 1 - I didn't need the spaciousness of the upper body of the mummy, and 2 - I found the rectangular one to be more versatile with the way one can use it in bag mode or fully unzipped as a throw. I sometimes use it as a liner in the winter by zipping up only a short footbox and then keeping the rest essentially doubled up on top, rather than compressing it beneath me, which decreases its insulating function.
I am careful with my gear and have not had any issues with robustness. I would choose the rectangular version again today. Cheers.
@@PaoloFrancesco99 Haha if only. Thanks for the additional info - really helpful. Just need to find the best way to source one now... ATB
FWIW: I think the Aegismax mummy bag has 'stitched through' baffles . . . . not boxed/walled baffles . . . . . so a stretchy thermal bag liner is something you may want to have on hand. The AEGISMAX Thermolite sleeping bag liner is said to add 5°~8° celsius more warmth. (Doh! I just read the comment from Paolo below; 'Each down chamber is also stitched through a single layer, i.e. there's no insulation at the stitch lines'.)
@MuddyDuck - A fellow in the comments above added a link to another version of this bag available in the UK. It's called NatureHike.
My wife bought herself a AEGISMAX NANO2 as it has baffle walls . . . my "plain old" Nano1 being stitched through led me to then purchase a WINGACE (Model : E-Chun-G) from AliExpress. It has baffles - a separate zip for the feet area - can be fully opened as a throw - can be bought with the zip on the Left or Right side - I bought 1,000g fill weight; size: 215 x 85cm.
I cant find the rectangular version anywhere :(
Have you tried Amazon? It's available there: www.amazon.com/gp/product/B01LZKAC25/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
In case the link doesn't work, the name in Amazon is: AEGISMAX Outdoor Ultra Light Goose Down Compactable Sleeping Bag, 78 x 31 - Inch
Is the costco as warm and thick as the aegismax? It looks like it in the video.. I am wondering if i should buy 2 costco blankets (which would cost me 80euro her in germany) or 2 aegismax rectangular sleeping bags. I want to be able to bike pack with a folding bike and my hammock in summertime (until 7 degrees celsius lowest night temp). But which is a better buy in your eyes for underquilt topquilt setup?
I kept the rectangular Aegismax and it just so happens that I used it up in the mountains this summer with my Hennessy hammock and Black Diamond (costco) underquilt. However, I also added my Alps Mountaineering Razor liner. The Aegismax is longer than the BD quilt and has substantially more loft and warmth. Since compressed down has little insulating value, I really like using the Aegismax in top quilt mode, where I leave only the bottom zipped to create a foot box. The rest is basically doubled up on top of me and the result is very cozy. One layer of the BD underquilt is the risk for a cold sleeper like me, so I used one more layer by getting into the Razor liner also to avoid hammock CBS, but the Razor is not so compact for your bike packing purpose. If you are considering two Aegismax: one for top quilt and the other for fashioning a bottom quilt, I think that would be a really nice hammock system. There is certainly a way to modify the Aegismax to work as an underquilt while leaving the option to use it as designed too. My underquilt modification for the BD quilt used a little sewing at the ends to create a cinching feature with shock cord. I shaped the long sides by folding over and using KAM snaps. The fold provided a channel to hold the end to end cords (mostly small diameter parachord, but with some length of shock cord) which clip into the ends of my hammock. I hope this helps. I'm happy to reply to a follow-up question.
Can you put a link to the Costco quilt? I can’t find it anywhere.
I wish I could provide a more useful link. Costco is a discount bulk items store in the USA, and it seems they might not carry these down throws anymore. Hammock camping DIY types have posted many DIY underquilt designs on UA-cam. I bought mine a few years ago during a Christmas sale for just $20, so I got two. The brand at Costco and at my store (also no longer sold) is Black Diamond. It comes with a flimsy but effective stuff sack. Here's a link from Amazon below, but it's a bit pricey as of this response. You can find alternatives by search terms like "down throw", "60x70 down throw", etc. There are cheaper ones available. Just make sure the materials are suitable if you plan to use it for outdoor activities, i.e. avoid cotton shell. Good luck.

Thanks really appreciate it. I just ordered the aegismax; hopefully it'll be worth the money as most reviews praise it.
@@RUGOHAN I hope you like it. Which one did you order? Mummy or rectangular?
hey, I ended up getting two of them one for my son and I. Things are sweet and we both go the mummy ones.
No zipper tube, No way.
Sure, I like zipper tubes on my 0 F degree and 20 F degree bags. They're needed for cold weather bags. These Aegismax models are not cold weather bags and they're not trying to be. Each down chamber is also stitched through a single layer, i.e. there's no insulation at the stitch lines. One wouldn't find this on a cold weather bag either.
@@PaoloFrancesco99 Yes, and I don't have one in front of me. I know all that you said. I didn't know it as a result of seeing the specifications on any site that sells it. It wasn't specifically noted in your video. I was passing along information for people who are not as educated as you and me. I would think that construction and specifications would be covered in detail.
