This product is pretty amazing. I've used the "extreme" version, and had a decent night of sleep in serious winter conditions (-15 to -20 degrees celsius). Its also great to use as a "one man tent/poncho" if you are resting for a short period of time. Its pricey, but gives you a sleeping bag/tarp/tent all in one. Strap it on the outside of your pack when going outside and you be safe and warm in all conditions.
I just got one and its instantly my favourite bit of kit. I’ll fine any excuse to wear/ use it. So versatile, so durable, water proof, wind proof, tarp, hammock, shelter, sleeping bag, its the best.
Now that is the most in depth look at this item, and the way you show so many different uses for it is excellent! Nothing better than a proper demonstration on a product. I think I can speak for all us viewers when I say thank you very much for your in depth review. Best regards to you :)
I love my Jerven Fjellduk. Snowcave, hammock pod,bivvy, poncho - for winter, autumn alpine use. Thank you for the excellent review. I had not seen the use as a hammock. I use it as a insulation for my normal hammock but I will try it like this as well.
Yes I have a Thermo XL. Wanted it to be big enough to easily cover the hammock, bivvi bag for 2, etc. I really like your idea of the hammock though, sometimes I might have the Jervenbag with me, but not the hammock. I always have rope, and in autumn and winter, always have the Jerven. Oooh how nice not to have to sleep on the ground!
Great revue you`ve covered a lot of uses for this piece of kit and it shows that you have used it many times . It has got me thinking now and yet another item is on my wishlist . Thanks hogweed from England
Thank you for your input! It makes it hard to decide, but I have some time until I have scratched money together to buy one of them! The Jerven will be extra expensive because the moms and the post-fees.. The Helsport-one can I buy in the shop here. Ulrica
Nice reviev. The Jerven Thermo Hunter is my favorite as well. For me it was worth the money, but I spendt a long time considering before I made the decision. I tend to not sleep well and the extra space is nice during restless nights. With a light sleeping bag it is always warm enough. Once I had to use it as rain gear during the walk home. I bet I was quite a sight during the last few kilometers, in the "civilcation", but it did the job well enough.
Thanks for this review! I'm in need of some rain gear but I'm torn between going the poncho way or getting a jacket/trouser combo. The Fjellduk is really interesting in it's versatility, however as my my main use probably would be as a poncho I'm a bit concerned about the condensation issues you mention (I'm looking at the original, as I'm not really needing it for added insulation). How would you go about ventilating it properly while hiking with a back pack?
Hei! I have been using the Helsport Fjellduk for some years, and slept in it in snowy condition, -5 C, with a summer sleeping bag inside. It keeps you warm, but there is lots of codensation. The Helsport is cheaper, it weighs less, less volume when compressed, and its very good for wind and rain protection. In emergency, you can light a graveyard candle inside if you are sitting upright. That helps alot on condensation, and keeps you warm in very cold weather. Jerven is a better product thoug.
Hello Odd, finally, today I got me a Jerven Fjellduk. I have been waiting a long time. Now I will watch this video and learn how and what I can do with it. Happy greetings from Sweden. :-)
Phenomenal piece of kit Odd, kind of happened upon this through Sepp Waldenwerk and Susanna Williams. Very impressed! Thanks for a great review. Still winter here in Canada (-33C last night), could use a Jerven/sleeping bag combination on the trail!
Thank you for this informative review. I came across it quite by accident on youtube and have since been looking into it. I wish I'd seen it a month ago, as I just purchased a kifaru woobie express, but this looks much better. If I get one, I'll more than likely use it as a insulated outer bag for my hammock under my rainfly. You've had it over a year, I wonder if you've used it much and how well its holding up? Thanks again
The woobie does look like a good product, its a bit smaller than the Jerven bag though. I`ve had mine for a year or so, but I have been using Jerven Bags of the same type for years in the army. And they all hold up very well, I have never experienced any terminal damage. Sparks from a campfire will melt a hole, but its easy to patch. Zippers have never failed. Mine is still in mint condition, even after been used as a hammock, tent and outer bag in winter overnights. I can and will higly recommend it. Only downside is the prize, its expensive. Thanks for your interest. Odd
if you have the woobie express, I'd recommend to you the "Jerven Bag Original" , it's uninsulated, and the woobie express would be the insulation under it. the "Jerven Bag Original" is also a great underquilt.
I have not much experience with the helsport one, beside lokking at it and examing it a bit. I havwe a lot of experience with the Jerven. The biggest difference must be the insulation, primaloft as used in the latest version of the Jerven bag is top of the line for this kind of use. It is much like wool, keep insulating even when wet, and it dries quickly. The old Jerven did not dry quickly. -Odd
Great video and great idea! I have a couple questions about the jerven bag. What type of material is it on the outside? It seems pretty heavy duty. Is it a silicon nylon or poly nylon? Is it 1.9 oz or thicker than that?
Hi Nathan, I do not know what type of nylon it is. You may find some info at the producers site: www.jerven.com/the-jerven-bag_1 Its thin, but still string and do withstand sharp twigs and rocks very well. Thanks for watching, Odd
Great review of the product, and I'm ordering one now. I'm interested in your other kit in the video, as it looks very well thought out. What pants, jacket and pack are you wearing? Thanks, Odd.
Hi, The pants are Haglöfs rugged Mountain Pants, jacket, an old membrane type, not specially great. Under the outer clothing I wear a wool kit expedition type.Brand doesnt matter much, as long its close to pure wool and comfortabel to wear. The pack is the Norwegian Army Battle pack, a 35 liter with good straps and waist belt. Good solutions to strap on sleepingbag, tent etc. It`s available on the free market. Thanks for watching! Atb, Odd
wow, a hammock with this thing ? (i got the same one) but never thought about making a hammock out of it.. Sure it wont destroy it ? i like where you stretch a rope between two trees and pull it thru the closed jerven - Zipper on top or bottom, put a sleeping bag and sleeping pad in it, on the ground - get kind of a small tent that way...
nice review Odd. Looks like a multipurpose peace of gear. I like that its a decent size not small like some and the primaloft is good stuff thanks for sharing atb John
Hej Odd! Thanks for a nice video in a lovely forest and a good review. I have wanted one for many years but first it was hard to find in Sweden and then I think the prize was high. Now I can buy a version of Helsport Fjellduk at the XXL-store. Is it any difference between Jerven and Helsport? After this review I really want to have one, but I can only get the Helsport one easy. Thank you for sharing! Ulrica
***** I ask a doctor that ones, and he said that a normal healty person will wake up and feel you cant get enough air, and yes, I have experiennced that myself, not in this though.
Hej Odd, dottern har varit i nord Norge på arbetspraktik. Hon frågade om hon skulle köpa nåt med sig hem så jag flyttade över pengar och hon köpte det som fanns på Intersport där hon var, det blev en Hunter, mountain camoflage. Jag är hel nöjd hittills. Igår blev det så sent och idag blev det annat så jag har inte tittat på din video än. Men jag ska. Behöver lite tips och råd så här i början. Ulrica
Zipper is still the same non-waterproof type as far as I know, I have, and many others have been sleeping in Jerven-bags. No problem, its not completly tight, both zippers and all corners are open for air ventilation. If you close it up to much you will get condensation inside, so its recommended to change the air ones and awhile by opening a gap. Odd
+Wild Outdoors UK Hi Jay, thank you I `m fine. The one I have is the Jerven Hunter. It has the same insulation as the Thermo. But its bigger. Original size is 143x143cm as a bag, Hunter is 220x104cm as a bag, and all different king-size models are 220x143cm. I feel rthe Hunter is the most useful, as a bivi, as a tarp or just as a sleeping bag or sleeping bag cover. I `m very pleased with mine and used it a lot, a bit expensive, but it will last you a very laong time. Here you can see another video of the bag: ua-cam.com/video/34jTeP1j_M8/v-deo.html
Hei, Ei tysk dame her på youtube som heter Susanne har den som heter king size thermo og henger den rundt hele køya si. Hun bruker den slik på vinteren. Den jeg har, og sikkert du også er litt kort for å henge hele hengmattan inni. Rune / Bumbling Bushcraft bruker jerven og hengmatte sammen, vet ikke om han har prøvd den som underquilt. Du kan spørre han..? Odd
When I was in the army we had these, if we were going to sleep in a tent or our RIBs we skipped the sleeping bag and used these only (since they occupy less space and weight than a sleeping bag), when we slept outside during the winter under open sky we had these as an external sleeping bag and our sleeping bags inside the jerven, only reason to have a tent then was to keep the bolts in our rifles to freeze stuck which sucked, solution? sleep with the rifle, room for multiple lovers in these bags :p
It was`nt at the time this video was made, have not checked now. You can take a look at www.jerven.com and www.raymears.com, both ship internationaly. Atb, Odd
As this bag offers NO INSULATION from the cold ground or the cold weather, it would be interesting to see you actually apply what you show in this video for a longer period of time. Try laying inside it, as you show, for more than a minute, and then preach about its capabilities. Unless it's a very hot night, this Jerven CANNOT be used as a sleeping bag. You were most probably commissioned by the manufacturers to spread the same LIES they tell on their site. In terms of warmth, this Jerven is inferior to any summer sleeping bag. Believe me, I speak from my own direct and dreadful experience in the field with it. It is an overrated and overpriced piece of gear that fails lamentably to meet it's manufacturer's specifications. Stop playing in front of the camera, and try to actually enjoy the outdoors. You'll see then that the Jerven Hunter is not the way to go.
I'm not joking at all! Don't expect this bag to perform like this guy shows in his review. Better think of this Jerven more like a slightly insulated (60gr/sqm) bivi that doesn't breathe at all. As I said before, there is no way you can use it as a sleeping bag. I made the mistake of replacing my summer sleeping bag with this in a summer hike in the mountains, and I wasn't able to sleep at all, that's how cold I was in this bag. By the way, I should mention that I used all the clothes I had on me. The sleepmat may cover your back/side, but you should ask yourself if you have enough clothes, and if they are warm enough. The bag offers SOME insulation, but don't expect the whooping 29 degrees C temperature increase claimed by the manufacturer. It is well built, waterproof (to some extent), non-breathable, and much colder than a summer sleeping bag. Please refer to my other comments about this bag. After my experience, I wrote to all the UA-cam users who reviewed this, or another version of this bag: Alloutdoor1, KM Hiker, and others. It would be interesting to see their replies as well.
Well sir, I`m sorry you have had a bad experience with the jerven bag. First of: I`m not a seller, I have not got anything from the company or anyone else to do that video. If you refere to the original jerven bag, that one is without any insulation, and works only as a windbreak/raincover in my mind, and camouflage of course. The bag called "hunter" does have some insulation. You can allmost compare it with a US poncho with a poncho liner in thickness. But the insulation value are higher in the hunter. I have both, so I know. I have used this bag for many years before I spent the big money on my own. As a former QRF soldier and officer I have used this bag many nights, in all seasons. It is not a replacement for a sleeping bag, at least not in any other season than summer. But its a reinforcement layer for a sleeping bag. After my military service, I have used it mostly as just that, but also as a "tent"/ cocoon around my hammock during wintertime. Also as a reinforcement, replacement for the underquilt. And it works very well for that. If someone belives it is a krytonite-super product that can do magic, I apologize if I have led someone to belive so. The benefit with a product like this compared to a bivisack, is that it can be used to so much more. As it is waterproof and actually is a tarp with zippers all around, it can be used as a tarp. At the same time, as it is waterproof, you will experience condensation build up inside if it closed. Thats a big downside. But you will also get that in a goretex bivisack too if you close it up. So yes there are some cons, none waterproof zippers and condensation build-up to be the biggest. Pros: it is big so when you sit down on a a rock or stump, you can sit normally and create a big room around you with warm air. thats a great advantage as a wind sack or emergency bivi/shelter. It is insulated with a material that keeps on insulating when wet and dry up quicker. The old ones had some other kind of insulation, and got much colder when it got wet. I know, cause I have used both types. Most people I know who has this bag, are hunters. They use it when sitting and waiting at the blind, and/or as a emergency tool if someone or themself get injured or need to get a quick shelter up. There are also other types. like the one called extreme, that one has 3 times the insulation as the hunter model. But then it gets very big and bulky, almost as big as a arctic sleeping bag. And you will still need a sleeping bag inside to have a comfortable night sleeping during winter time up here. As a survival bag, as it is design as, it is by my mind one of the best products out there when you consider weight, durability, and protection, but not the price. Yes I agree it is very expensive, I got mine on special offer sales though. About the factory testing that claimes 29 degrees difference, well I have never expereienced that. Then agian, I have never had those expectations either, cause I used it years before I read anything about that. And yes, I had a smile on my face when I finally read it. It is good, but not that good.
Thank you for your disclaimer and for finally agreeing with me that this bag is not actually what the manufacturer claims to be. The version I have is Jerven Thermo Hunter with 60g/sqm Primaloft insulation, the same as yours. You shot this video in 5°C. You expressly say in the video (at 5:45) that “it’s terribly warm” with the Jerven worn as a poncho. At 6:57, you say that “because it’s not breathing, it doesn’t lose heat either”, but it does, through the zippers and grommets. Because there is no flap to cover the zippers, the cold finds its way inside precisely through those zippers, grommets, and through the open gaps that are present in each corner that ends with a zipper. At 7:22, you say that it can be used “as a sleeping bag, if it’s not too cold”, and then, at 9:39, you say “in the winter time, you just roll your sleeping bag inside this”, making the viewer to believe that this Jerven is suitable to be used as a sleeping bag in any other season than winter. Now, someone who goes deep into the bush for more than a few days, having no vehicle and no access to roads, and having to rely only on the gear he has on his person and in his backpack, this might seem like the perfect solution to replace his sleeping bag and his rain gear, thus cutting down both weight and bulk. When using it as a hammock, you say again, at 15:58, that “it’s pretty warm already”, thus leading the viewer to believe that he could have a comfortable sleep in this bag at a temperature of 5°C, or even less (if he thinks that you are actually going to spend the night in that setup). At 20:18, you say you have “slept in it many times, during the military service also”, which again might make the viewer think that this bag is a 3-season sleeping bag, standard issue of the Norwegian army. Is it? When I bought this Hunter bag, I wasn't expecting it to be made out of kryptonite, but I was hoping to be somehow warmer, i.e. closer to the manufacturer's specifications and to what you assert in this video, or in your Quinzhee-night video, where you claim that you could have spent the night in 0°C just with the Jerven. I tried it in 7°C, and it couldn't handle it. So, as far as it's insulating capacity is concerned, I found it to be very poor. Obviously, even more so when wet. It would also be interesting to know the vice versa - in summer temperatures, how long can you wear it as a poncho in pouring rain before getting drenched in your own sweat? Because you repeatedly praise the warmth that this Hunter allegedly provides, I came to the conclusion that you don’t actually use it in the real world, but you only mislead people with regard to its real capabilities, thus tricking them into buying a false advertised product. Your video seemed to me very well thought in this regard, and that is why I presumed that you were either commissioned by Jerven to do this video, or you actually work for their company. If I was wrong, please accept my apologies. In my opinion, a review should cover all the aspects of the product, i.e. pros & cons, not only the positive aspects. You would say that you have already covered that by talking about the extremely high price tag, the weakness in not being exactly waterproof because water can leak through those zippers, and the condensation problem. But these are just SOME of the cons (also found on the Jerven website), not ALL of them. From someone who claims that he has extensively used this bag over the years, in all kind of weather conditions, especially in a rather harsh environment like Norway, I would have expected a much more detailed and honest review of this bag, not this poor advertisement that it turned out to be. Mind you, when posting reviews of one product or another, you are supposed to share your knowledge with other people who are not familiar with that product. You have the responsibility of educating them, and not look like a kid in a candy shop, being all ecstatic about the object of your review. I would really appreciate if could post a second part of this video, thus making a real and detailed review of this bag, that would cover all the other aspects that you chose to ignore here. If you need any suggestions in this regard, I would be more than happy to provide them to you. Until then, could you please tell me and the others who read these comments, what is the actual comfort temperature range of the Jerven Hunter, based on your own experience with it?
@@tsonytxp762 Brother, with all that info you added in this comment, you might have the bones of a video yourself. Have you considered making a video regarding your experiences on this topic?
This product is pretty amazing. I've used the "extreme" version, and had a decent night of sleep in serious winter conditions (-15 to -20 degrees celsius). Its also great to use as a "one man tent/poncho" if you are resting for a short period of time. Its pricey, but gives you a sleeping bag/tarp/tent all in one. Strap it on the outside of your pack when going outside and you be safe and warm in all conditions.

Nice review I really want one of those bags. I saw one being used in an outdoor camp & was hooked!
Yes I have a Thermo XL. Wanted it to be big enough to easily cover the hammock, bivvi bag for 2, etc.
I really like your idea of the hammock though, sometimes I might have the Jervenbag with me, but not the hammock. I always have rope, and in autumn and winter, always have the Jerven. Oooh how nice not to have to sleep on the ground!

Thank you for your answer. I just finished reading some info in the Jerven 2012-catalog. Very interesting info. Honza

Hello Odd, finally, today I got me a Jerven Fjellduk. I have been waiting a long time. Now I will watch this video and learn how and what I can do with it. Happy greetings from Sweden. :-)
Phenomenal piece of kit Odd, kind of happened upon this through Sepp Waldenwerk and Susanna Williams. Very impressed! Thanks for a great review. Still winter here in Canada (-33C last night), could use a Jerven/sleeping bag combination on the trail!
wow! Still that cold? Over here its spring!
The Jerven Bag is a good piece of kit, when used correctly.
Thanks for watching, happy trails
Very nice review showing the versatility of it!
Thank you for sharing!

Ak, the fjellduken. I've seen it before in a catalogue. Very practical product!
Okay. Then I will wait until I can get a Jerven one! Thank you for your reply!
Ulrica
for the extra weight of the poncho I carry coat trousers and a poncho poncho makes a good ground sheet t he end of the day or emergency shelter
not bad that sure would be handy to have in the pack that is for sure. Pretty expensive but it looks like a great product.

wow, a hammock with this thing ? (i got the same one) but never thought about making a hammock out of it..
Sure it wont destroy it ?

Zipper on top or bottom, put a sleeping bag and sleeping pad in it, on the ground - get kind of a small tent that way...
I checked this link immediately. :o) Very clever. Great idea!! Do you have any experience with The Jerven Bag Original? h
nice review Odd. Looks like a multipurpose peace of gear. I like that its a decent size not small like some and the primaloft is good stuff thanks for sharing atb John
Thank you John, its a good product, a bit pricy, but for sub zero enviroment its a good product that can save lifes for sure.

Hi Odd,this is an excellent review!!! I never seen anything like this before. Very interesting product. Thanks for your video. h
Hej Ulrica, hva ble det? Thermo, hunter eller king size ??
Vil tro du blir fornøyd.
Odd
If you close all the zippers and uses it as a sleeping bag, will you get enough oxygen to sleep through the night?
***** I ask a doctor that ones, and he said that a normal healty person will wake up and feel you cant get enough air, and yes, I have experiennced that myself, not in this though.
Hej Odd, dottern har varit i nord Norge på arbetspraktik.

ok, thanks for those pointers. Having looked into it even more, I'll probably go with rain gear and leave the Fjellduken for another day :)
It´s been some time since this review was made, is the leaking zippers fixed? Also, if you would want to sleep in this, is air circulation a problem?
Zipper is still the same non-waterproof type as far as I know, I have, and many others have been sleeping in Jerven-bags. No problem, its not completly tight, both zippers and all corners are open for air ventilation. If you close it up to much you will get condensation inside, so its recommended to change the air ones and awhile by opening a gap.

Where to purchase one apart Norway?
I dont know actually, but its no problem to order it from jerven.com.

Hi Odd
hope your well? what model is your Jerven Fjellduk? as im intrested in buying one and there are sevral difrent types.
Regards
Jay
+Wild Outdoors UK Hi Jay, thank you I `m fine. The one I have is the Jerven Hunter. It has the same insulation as the Thermo. But its bigger. Original size is 143x143cm as a bag, Hunter is 220x104cm as a bag, and all different king-size models are 220x143cm. I feel rthe Hunter is the most useful, as a bivi, as a tarp or just as a sleeping bag or sleeping bag cover. I `m very pleased with mine and used it a lot, a bit expensive, but it will last you a very laong time.
Here you can see another video of the bag: ua-cam.com/video/34jTeP1j_M8/v-deo.html
+NorwegianBushcraft thank Odd I have found a dealer in the uk that imports them so I'm going to buy one in the new year!!!!
You will not regret, its a great product.
Atb, Odd
Hei,
Ei tysk dame her på youtube som heter Susanne har den som heter king size thermo og henger den rundt hele køya si. Hun bruker den slik på vinteren. Den jeg har, og sikkert du også er litt kort for å henge hele hengmattan inni. Rune / Bumbling Bushcraft bruker jerven og hengmatte sammen, vet ikke om han har prøvd den som underquilt. Du kan spørre han..?
Odd
My only concern without basha would be leak of water in rain through zip. After all this set up would be a s DIRE situation an Emergency.
Yes, water thru the zipper is the biggest issue. You have to place it in such a way that the zipper is under your self.
Thank you for making this video ... Tusen takk !
Thank you for the review.
And thank you for watching. Hope you liked it.

When I was in the army we had these, if we were going to sleep in a tent or our RIBs we skipped the sleeping bag and used these only (since they occupy less space and weight than a sleeping bag), when we slept outside during the winter under open sky we had these as an external sleeping bag and our sleeping bags inside the jerven, only reason to have a tent then was to keep the bolts in our rifles to freeze stuck which sucked, solution? sleep with the rifle, room for multiple lovers in these bags :p
TheSatanicon Thanks, yes its a very good product.

This looks great but I can not understand most of what you are saying. I am not sure if that is because you speak so softly or the background noise.
Are you hiding from Swedes or Finns or Danes?

As this bag offers NO INSULATION from the cold ground or the cold weather, it would be interesting to see you actually apply what you show in this video for a longer period of time. Try laying inside it, as you show, for more than a minute, and then preach about its capabilities. Unless it's a very hot night, this Jerven CANNOT be used as a sleeping bag. You were most probably commissioned by the manufacturers to spread the same LIES they tell on their site. In terms of warmth, this Jerven is inferior to any summer sleeping bag. Believe me, I speak from my own direct and dreadful experience in the field with it. It is an overrated and overpriced piece of gear that fails lamentably to meet it's manufacturer's specifications. Stop playing in front of the camera, and try to actually enjoy the outdoors. You'll see then that the Jerven Hunter is not the way to go.
I'm not joking at all! Don't expect this bag to perform like this guy shows in his review. Better think of this Jerven more like a slightly insulated (60gr/sqm) bivi that doesn't breathe at all. As I said before, there is no way you can use it as a sleeping bag. I made the mistake of replacing my summer sleeping bag with this in a summer hike in the mountains, and I wasn't able to sleep at all, that's how cold I was in this bag. By the way, I should mention that I used all the clothes I had on me. The sleepmat may cover your back/side, but you should ask yourself if you have enough clothes, and if they are warm enough. The bag offers SOME insulation, but don't expect the whooping 29 degrees C temperature increase claimed by the manufacturer. It is well built, waterproof (to some extent), non-breathable, and much colder than a summer sleeping bag. Please refer to my other comments about this bag. After my experience, I wrote to all the UA-cam users who reviewed this, or another version of this bag: Alloutdoor1, KM Hiker, and others. It would be interesting to see their replies as well.
Well sir, I`m sorry you have had a bad experience with the jerven bag.
First of: I`m not a seller, I have not got anything from the company or anyone else to do that video.
If you refere to the original jerven bag, that one is without any insulation, and works only as a windbreak/raincover in my mind, and camouflage of course.
The bag called "hunter" does have some insulation. You can allmost compare it with a US poncho with a poncho liner in thickness. But the insulation value are higher in the hunter. I have both, so I know.
I have used this bag for many years before I spent the big money on my own. As a former QRF soldier and officer I have used this bag many nights, in all seasons. It is not a replacement for a sleeping bag, at least not in any other season than summer. But its a reinforcement layer for a sleeping bag.
After my military service, I have used it mostly as just that, but also as a "tent"/ cocoon around my hammock during wintertime. Also as a reinforcement, replacement for the underquilt. And it works very well for that.
If someone belives it is a krytonite-super product that can do magic, I apologize if I have led someone to belive so.
The benefit with a product like this compared to a bivisack, is that it can be used to so much more. As it is waterproof and actually is a tarp with zippers all around, it can be used as a tarp. At the same time, as it is waterproof, you will experience condensation build up inside if it closed. Thats a big downside. But you will also get that in a goretex bivisack too if you close it up.
So yes there are some cons, none waterproof zippers and condensation build-up to be the biggest.
Pros: it is big so when you sit down on a a rock or stump, you can sit normally and create a big room around you with warm air. thats a great advantage as a wind sack or emergency bivi/shelter. It is insulated with a material that keeps on insulating when wet and dry up quicker. The old ones had some other kind of insulation, and got much colder when it got wet. I know, cause I have used both types.
Most people I know who has this bag, are hunters. They use it when sitting and waiting at the blind, and/or as a emergency tool if someone or themself get injured or need to get a quick shelter up.
There are also other types. like the one called extreme, that one has 3 times the insulation as the hunter model. But then it gets very big and bulky, almost as big as a arctic sleeping bag. And you will still need a sleeping bag inside to have a comfortable night sleeping during winter time up here. As a survival bag, as it is design as, it is by my mind one of the best products out there when you consider weight, durability, and protection, but not the price. Yes I agree it is very expensive, I got mine on special offer sales though.
About the factory testing that claimes 29 degrees difference, well I have never expereienced that. Then agian, I have never had those expectations either, cause I used it years before I read anything about that. And yes, I had a smile on my face when I finally read it. It is good, but not that good.
Thank you for your disclaimer and for finally agreeing with me that this bag is not actually what the manufacturer claims to be. The version I have is Jerven Thermo Hunter with 60g/sqm Primaloft insulation, the same as yours. You shot this video in 5°C. You expressly say in the video (at 5:45) that “it’s terribly warm” with the Jerven worn as a poncho. At 6:57, you say that “because it’s not breathing, it doesn’t lose heat either”, but it does, through the zippers and grommets. Because there is no flap to cover the zippers, the cold finds its way inside precisely through those zippers, grommets, and through the open gaps that are present in each corner that ends with a zipper. At 7:22, you say that it can be used “as a sleeping bag, if it’s not too cold”, and then, at 9:39, you say “in the winter time, you just roll your sleeping bag inside this”, making the viewer to believe that this Jerven is suitable to be used as a sleeping bag in any other season than winter. Now, someone who goes deep into the bush for more than a few days, having no vehicle and no access to roads, and having to rely only on the gear he has on his person and in his backpack, this might seem like the perfect solution to replace his sleeping bag and his rain gear, thus cutting down both weight and bulk. When using it as a hammock, you say again, at 15:58, that “it’s pretty warm already”, thus leading the viewer to believe that he could have a comfortable sleep in this bag at a temperature of 5°C, or even less (if he thinks that you are actually going to spend the night in that setup). At 20:18, you say you have “slept in it many times, during the military service also”, which again might make the viewer think that this bag is a 3-season sleeping bag, standard issue of the Norwegian army. Is it?
When I bought this Hunter bag, I wasn't expecting it to be made out of kryptonite, but I was hoping to be somehow warmer, i.e. closer to the manufacturer's specifications and to what you assert in this video, or in your Quinzhee-night video, where you claim that you could have spent the night in 0°C just with the Jerven. I tried it in 7°C, and it couldn't handle it. So, as far as it's insulating capacity is concerned, I found it to be very poor. Obviously, even more so when wet. It would also be interesting to know the vice versa - in summer temperatures, how long can you wear it as a poncho in pouring rain before getting drenched in your own sweat?
Because you repeatedly praise the warmth that this Hunter allegedly provides, I came to the conclusion that you don’t actually use it in the real world, but you only mislead people with regard to its real capabilities, thus tricking them into buying a false advertised product. Your video seemed to me very well thought in this regard, and that is why I presumed that you were either commissioned by Jerven to do this video, or you actually work for their company. If I was wrong, please accept my apologies.
In my opinion, a review should cover all the aspects of the product, i.e. pros & cons, not only the positive aspects. You would say that you have already covered that by talking about the extremely high price tag, the weakness in not being exactly waterproof because water can leak through those zippers, and the condensation problem. But these are just SOME of the cons (also found on the Jerven website), not ALL of them. From someone who claims that he has extensively used this bag over the years, in all kind of weather conditions, especially in a rather harsh environment like Norway, I would have expected a much more detailed and honest review of this bag, not this poor advertisement that it turned out to be. Mind you, when posting reviews of one product or another, you are supposed to share your knowledge with other people who are not familiar with that product. You have the responsibility of educating them, and not look like a kid in a candy shop, being all ecstatic about the object of your review.
I would really appreciate if could post a second part of this video, thus making a real and detailed review of this bag, that would cover all the other aspects that you chose to ignore here. If you need any suggestions in this regard, I would be more than happy to provide them to you. Until then, could you please tell me and the others who read these comments, what is the actual comfort temperature range of the Jerven Hunter, based on your own experience with it?
@@tsonytxp762 Brother, with all that info you added in this comment, you might have the bones of a video yourself. Have you considered making a video regarding your experiences on this topic?
