Features
Features
- 850+ Dry Loft Down-We partnered with Allied Down and Feather to create Dry Loft Down, a naturally water resistance down sourced from Eastern Europe and processed in the USA for maximum long-term loft. It is simply the best down for sleeping bags that exists. Dry Loft Down is responsibly sourced RDS certified with no wax-based waterproof coatings that cause down clumping and reduce loft over time.
- Body Mapped Baffles-Differential cut fabric and a combination of vertical and horizontal baffles with internal flow gates strategically puts goose down where you need it the most to trap warm air and prevent down migration in the baffles.
- Honest Temperature Ratings-With a commitment to honest comfort ratings vs. an industry standard survival rating, our Alpine 20 degree bag is built and independently tested to ISO standards to keep you comfortable at 20 degrees, not shivering throughout the night, leading to enhanced warmth and ultimate recovery.
- Ultralight, Ultra comfortable Fabric-Breathable Pertex Quantum 15D fabric with PFC-Free DWR coating prevents moisture from getting your bag from the outside, but still allows moisture to escape from inside your bag, while our soft 15D polyester fabric provides a comfortable next to skin feel.
- Anti-Snag Zipper-Two way YKK #5 zipper with anti-snag cover provides smooth zipper operation and prevents fabric from catching in the zipper.
- 3D Foot Box-A Footbox that mirrors the shape of your feet so you won't compress the down in at the bottom of your bag and create cold spots.
- 3D Contoured Hood-A hood that cradles your head and prevents drafting from inside the bag.
- Insulated Draft Tubes-Insulated and overstuffed draft tubes along the face and zipper trap warm air, prevent drafting and keep you better insulated.
- Integrated Pillow Attachment System-connection points inside the hood allow the Elite Dream Pillow to attach to your pillow so it stays put during the night.
- Internal Cell Phone Pocket-Keep your battery alive and warm with the internal pocket on the right side shoulder of the bag.

Great bag! I had it on a 3 night rifle elk trip in October with nighttime temps in the mid 20s. This bag is super warm for the rating. The zipper pulls smooth and doesn't catch. I used it with the dream pillow and the buttons made the pillow stay in place. What a great idea! Would absolutely recommend
Amazing sleeping bag perfect size
Super lite bag, also pretty impressive on how easy it maintains a comfortable sleeping temperature. I was using this bag for the first time in July on camping trip in Maine, (super humid) and I was completely comfortable all night. I would buy this sleeping bag over and over again. Keep up the good work everyone!!!!!!
Super excited to put this to use in the Colorado this year for archery elk. First thought is it’s very light and very comfortable!
Very impressed with this bag. I’m typically a cold sleeper but have used it in conditions just below 20 degrees and have stayed warm. If your on the fence try it out you won’t be disappointed
Much better than I thought it would be.
When I opened this sleeping bag up for the first time, I thought maybe something was missing...I can't believe how light weight this sleeping bag really is!
The craftsmanship and quality is the best in the industry, it's very comfortable and very warm. The zipper works great and doesn't snag, it's roomy enough for my 6' 220lb frame, and packs down into a tiny bag.
Can't wait to test this bag out in cold September weather.
This is my favorite sleeping bag I have ever owned. It is extremely comfortable due to the roomy cut and the soft inner fabric. The elite dream pillow attachment is also a big plus. The zipper is very smooth and reduces snags very well. I am a very cold sleeper for a man, my comfort limit in this bag wearing only wool thermals and socks and a 6.5 R-value pad seems to be about 25 F. Even at 25F only my legs or feet get cold enough to wake me. I still rate this bag very highly because it is an honest temperature rating for probably the vast majority of men (most men would probably be comfortable below 20F), but my body just doesn't create heat while I sleep. I just have to put on extra layers if it's going to be a cold night. Overall I gave it 5 stars due to the quality, warmth, weight, pack size and price for what you get. I would buy the Alpine 0 as well but I need something warmer for winter temps.
I have not had the opportunity to use it on a hunting / scouting trip, but I am impressed with the quality of materials, space, and warmth for the weight. Everything that I have bought from Argali has been top notch!
Great bag kept me warm when temps were in the teens. Only thing I wish is they would offer a wide version it was very snug around my shoulders
Have not had a chance to use the bag yet, but my son has one and I got a chance to look at it on an elk hunt last season. I had another top brand bag and after seeing this bag and noticing differences, had to have it! Excited to use it this upcoming hunting season!!
The 20 degree sleep bag worked great. Extremely light for back pack packing steep nasty country. And more importantly warm in those late November high country hunts. At first I was not thrilled by the pillow., but now it’s my favorite peace of gear. Together perfect back country sleep system!
I got it after season so I haven’t been able to use it yet. It feels great but I don’t have any field experience with it yet.
The bag worked great. The overnight temps were in the low 30's and I was never not comfortable. As far as packability the bag is incredibly light and packs down nicely. I am 100% satisfied with my purchase.
Bought sleeping bag for my nephew in Montana.
Avid Hunter and Hiker. He loves, loves it. Thank you for great quality gift. Gotta keep my favorite Aunt status.
Awesome bag.
The best bag for your money.
Its advertised to be a bit larger than some sleeping bags in the torso area but its still fairly tight. Im 6’2” 235 lbs and the length is great but still a little toght up top.
Spent the night out camping with it as soon as I got it For context, I hike, hunt, camp, fish and climb in the white mountains of New Hampshire. It's rugged country and I put my gear through a lot. Out of the box I noticed how light it is, which is a big reason for the purchase, but also how thin the face material feels. Hope durability isn't an issue. The first night was 31 degrees and I was initially cold in just baselayer top and bottom. Added a puffy and was ok. My pad was a nemo quasar insulated but it isn't as high an R value as my tensor, So that may have something to do with it. The bag has high loft but because of the light weight pertex it didn't have that blanket like weight and feel to it. I'm looking forward using it again with better results. My purchase was largely based on the positive reviews of the bags warmth and it's true 20 degree rating..
Hey Jeff,
Thanks for your review. Yes, the sleeping pad will make a difference in being warm and comfortable in your sleeping bag. There is also a cinch near the top of the sleeping bag to help with cold air getting into the bag.
Please reach out if you have any other questions!

Recently acquired this bag and took it out for a multi-day hunt in the mountains. I was at 8,000ft and the overnight lows were at 18-22 degrees over the duration of my trip. The sleeping bag performed well, I was using it in conjunction with the Argali pillow, but also with a sleeping bag liner. I stayed warm all night! I was impressed at the design of this bag, specifically with the down placement in critical areas of the body to keep warm. I also own Feathered Friends sleeping bags which have been my standard for a performance down bag. I would say that the Argali bags match the performance of the feathered friends bags. I will be looking forward to see how it holds up over time!
Used the sleeping bag on two different backcountry hunts in Oregon and Idaho. The bag worked really well in sub freezing temps. The bag’s technology allows for sweat and moisture to escape.
Haven’t had the bag in below freezing temps yet but I can tell you this is a quality built bag. The loft is incredible . I originally bought it without the pillow as I have had many camp pillows and none of them were better than my rolled up coat in a stuff sack. This one is by far better than anything I have seen. The one side has a very soft fabric that makes it great. You unzip it and can put what you want in it to make it as firm or as soft as you prefer. What puts it head and shoulders above others is the bag has a little tab on each side at the top with a button hole in it and the pillow has a hidden button on each side. You put the button in the tab on the bag and no more chasing your pillow all night. I know there are those tough guys that say a pillow is not needed but I can tell you when you are startled by the alarm in the morning meaning you slept sound all night you will get it. There is nothing much better or needed in the Elk wood than a good nights sleep. Not many hours in those nights and making the best of them will benefit you in the days to come.
I hate mummy bags, always have. I've ended up carrying more weight in the past to avoid the mummy bag at all cost. This bag has completely changed the game for me. As a side sleeper, I do not get caught in a web every time I try to roll over in this bag. I am comfortable and warm. It packs light, yet is durable and warm. 10 days in Alaska hunting moose on the coast, we were constantly wet, but this bag not only kept me warm but also dry as we woke up every morning and the top of the bag (inside our tent) was damp. 10 out 10 recommend.
Picked up the 20-degree bag last spring. After a spring of Montana bear hunts, a very wet and cold sheep hunt and some elk hunts I have no doubt this will keep me warm well through the Montana rifle season. My wife runs really cold and has struggled to find a bag that works well, and she is blown away by how warm this keeps her.
Happy with the bag, packable and light, kept me warm in 0 to 5C weather. The bag was wet every morning in the chest area, not sure if from my breath?? Or moisture wicking from body heat and sweat?? The bag dried nicely over the day in the tent so the review stays a 5. Had it remained damp I'd give it a 4. My tent was dry, so it had nothing to do with drips from the tent roof.
Hey Aaron, it sounds like the Pertex fabric on your Alpine 20 degree sleeping bag was doing its job of helping the moisture from inside you bag escape and then drying well through out the day. I hope you have many more nights in store for it this Fall.
I’m a sleeping bag snob, I own or have owned many of the best bags in the ultralight backpacking world. The quality, comfort and function of this bag is as good as I’ve ever seen. The loft is impressive, the weight to warmth ratio is fantastic and the integrated pillow system is simple and streamlined. Argali hit a home run here. Great bag
Hey Ben, Thanks for the glowing review of the Alpine 20 degree sleeping bag. I Hope you are able to use and abuse it for the rest of this Fall. Good luck on all of your upcoming adventures.
Have used it a couple times this summer and the fit is perfect. Looking forward to using this for a couple hunts later this fall. The bag combined with the elite pillow is flawless. No more pillow slip in the middle of the night. Great product from a great company. Buy with confidence.
