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 0 degree bag is built and independently tested to ISO standards to keep you warm at 0 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 neck collar and 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.

The most comfortable and spacious sleeping bag

The most comfortable and spacious sleeping bag I have ever used. I hate most sleeping bags because I feel like a mummy in them. This bag has so much room and is so warm. Highly recommend.

A well thought out Bag!

I’m really impressed. This bag feels so much higher quality than many bags that are even at a similar price point or higher! I love the fit and the fact that’s actually a comfort rating unlike my previous bags. Probably my favorite thing is the integration with the pillow so I’m not chasing that thing throughout the night trying to sleep. Argali continues to deliver!

Alpine 0 degree bag

Just used it for the first time in idaho, couldnt wait for late season. Great bag, loved the roomy feel, ease of the zipper and the overall comfort. it was a bit warm for current temperatures but just slept with it unzipped, can't wait to get it up in the high country in late season. Its well made and definitely well thought out. Highly recommend it.

There is a lot to like about this sleeping bag!

There is a lot to like about this sleeping bag! It is very roomy and made of all high quality materials. Even on a night down to -6°F, I was able to stay warm and comfortable throughout the night. The pillow attachment also worked extremely well and made it very easy to get comfortable a not lose my head support as I moved around while I slept.

This is also one of the ONLY 0° bags that I found that included an internal cellphone pocket! Thai helps keep your phone safe and secure while saving your battery from the cold!

Overall, I’d highly recommend this bag! No complaints!

I’m a new Argali sleeping bag owner so I don’t

I’m a new Argali sleeping bag owner so I don’t have an exciting adventure story to go along with this review—yet.
I tried it out last night on my deck under the stars and it was negative 8 degrees at 6:00 am in New Hampshire.
I wore a pair of mid-weight socks, base layer long John’s, a cotton t-shirt and a lightweight sweatshirt.
I was a perfect temperature all night. Being a side-sleeper, I was very comfortable as stated in the description. My feet had plenty of room and were warm.
The zipper worked flawlessly. I’m a nasty critic when it comes to zippers. This zipper is an example of how they all should work.
With more clothes, a balaclava-style hat, and lightweight gloves, I’m sure this bag would handle 20 below temps comfortably. Thanks for an excellent product. 🇺🇸🇺🇸🇺🇸

Temperature rating is an honest comfort rating

The temperature is a true comfort rating not survival rating. Wish I had bought the 20 degree bag to save on space for walk-in sheep hunts in Alaska. Perfect for fly-in or boat-in hunts. Excellent bag for stretching the shoulder seasons.

Roomy

I purchase the pillow a year ago and have been looking forward to getting the bag, which I finally did late this season. The bag was as described roomy and warm, so for that it gets 5 stars. Where it fell short was when using it on my first hunt the button on the pillow tore off when I was tossing and turning. I must have been really tossing around to try and get comfy, so likely user error. But I did find it challanging to close in the hood with the pillow tucked inside. I feel like there could be some refinement to the system. Specifically how the pillow sits in or out of the hood. I like the concept but just didn’t find it worked out as well as I was hoping. Because of this, I found the hood a bit sloppy and not able to really tighten it down on those really cold nights. I’ll have to come up with a new plan for my pillow before heading out again. Great job on the bag, I finally feel like I found a bag that fits me well, except for the hood. 😉 one more thing. Ordering to Canada I was dinged with 300 dollars of tariffs. Unfortunate I won’t be ordering from the US anytime soon because of this, and should have looked into this before ordering as I would have found a local bag to purchase. ☹️

Hi Richard,

We're glad the bag itself was warm and comfortable. Regarding the hood design, there are two draw strings on the hood, one for the neck baffle and one for the hood so you can eliminate drafting on cold nights. It might take a little playing around to get the hood synched down around your neck but you should be able to get it nice and tight even witht the Elite Dream Pillow in the hood. And regarding the button pillow coming off, shoot us an email and we'll get it fixed or replaced!

We understand Canadian tariffs are frustrating. Unfortunately these taxes are set by the Canadian government and we have no control or influence over them.

Awesome

light weight and very warm. Used on a high country elk hunt, got into the teens and never even knew it. Roomy fit, and if any complaint I could come up with it could be a little shorter, I’m 5-9 and kinda swam in it length wise!

Great sleeping bag

Just used this bag on a 9 day late season elk hunt in the high country. Lowest temp was -1 that we could tell, and this bag didn't disappoint. I never knew it was even cold outside. Most nights with a base layer on, I was actually hot.

Couldn't be happier with my new sleeping bag. It definitely checks all the boxes for a quality bag with a true temp rating.

Quality and Truth

This bag is top notch and the weight was as stated.

We purchased 4 different bags from 3 manufacturers and no one else is accurate on weight.

I used this in the Brooks Range with a waterproof cover and it’s the best sleeping bag (and pillow) I’ve ever owned.

Hey Jeremy,

Thanks for taking the time to leave a review. I hope your adventure in the Brooks range was amazing. The pillow and sleeping bag combo will really improve your rest in the backcountry.

Great Bag!

Needed something more compact and though hesitant about a mummy bag I took a leap of faith. I’m 6’7, 270, and a side sleeper. Tall size was perfect for height and really worked well for side sleeping. Very comfortable and easy to move around in the bag. Only tested at right at freezing temps but definitely warm. Liked the pillow also. Glad I made the purchase.

Hi Bradley,
Thank you for taking the time to leave a review for our Alpine 0 Degree Sleeping Bag. We're so happy to hear that it worked out well for you, even though you were hesitant about the mummy style. We're glad the tall size was a good fit for your height and side sleeping preference. We appreciate your business and hope you continue to enjoy your sleeping bag on future adventures!

Favorite backcountry, cold-weather bag! True 0° rating!

Absolutely love this 0° backcountry lightweight bag! 0° rating is a true rating. Tested about 5° below zero stayed warm without any extra layers. Plenty of shoulder room and long enough for my height at 6’5”.

Looking forward to spring bear and fall Caribou in Alaska with this bag in my pack.

Hey Trent, thanks for taking the time to leave your review. We really are trying to change the sleeping bag rating system, with our true comfort ratings. I hope you have a great time using and abusing the bag in AK. Enjoy!

Convert from the quilt

Since the advent of the quilt, I was convinced I would never go back to a mummy bag. In fact, to ensure that I was warm in frigid temps, I employed a 22° quilt and a -10° quilt liner. This was primarily because of the restriction in movement offered by mummy bags.

I tried this at a trade show believing it would be the same story. It felt roomy and comfortable at the show so I took a gamble. I used it a week later in nighttime temps of 13°. Not only did I have all of the room I wanted to side sleep and adjust, but it stayed warm the entire night. This bag may have retired my expensive quilt system. Beyond happy with this bag. I cannot recommend it enough.

Thank you for the kind review E. Brown. We are always here to help people with the transition from quilt to sleeping bag. Hope you are able to get a lot of trips in those low temps and really get to abuse the 0 degree bag!

True Temp Rating!

Amazing bag that is comfortable and truly reflects the performance temperature. Purchased for a late season hunt I have coming up in Idaho later in 2025 but I took it on a hunt to the top of Mauna Loa a week ago and it did not disappoint. The temps only got down to 36 at night but I'm now very confident in packing the bag with me during the cold weather I expect in Idaho.

Thanks for taking the time to leave a review Brandon. I am sure you will find the bag plenty warm in the ID backcountry. Hope you are able to find some success on that hunt!

Great bag

I’m 6’3” and about 240LB. This bag fits great and will definitely keep you warm in 0 deg weather I bought the long with pillow. I don’t know if I needed the pillow but I didn’t see a downside to getting it. Comes with a storage bag and a compression bag which is nice since it is down you don’t want to keep it compressed all the time.

Hey Brandon, I think you will really love the pillow. Thanks for taking the time to leave a review.
