Product Reviews
Rated 5 out of 5 by from Tested in the harsh winter of Alaska (Size Reg, Zipper LH) I am 5’10 and weight 170lbs; I am a side, hot sleeper. Even though I have not tested this sleeping bag to it’s coldest rating, it’s performance was exceptional at -21°F (-29.4°C.) I slept out in the open without a tent or a bivy cover. I slept great but was overheating because of my parka. The wind chill was -27°F, however it didn’t make a difference since I didn’t feel any wind with the outer material (gore-tex windstopper.) It’s not waterproof, but it is water repellent, so it prevents condensation from soaking the down insulation. Some reviews mention it being cold, so keep in mind every sleeping bag rating has been tested with an appropriate sleeping pad and layers. Do your research on how to properly camp at below 0° temperatures. I changed into dry layers and paired it with: Sleeping pad R-Value 6.2 Switchback pad of R-Value 2 Total R-Value of 8.2. Down Parka (800 fill) Down booties Fleece lined base layers Mountaineering socks Fleece gloves Fleece Beanie Fleece balaclava Nalgene with hot water in between legs Also the sleeping bag is fitted for mountaineering, so I slept with my camera, batteries, boots, and gore-tex jacket inside. If you plan on having a lot more gear inside your sleeping bag, you might want to get the size Large. I cinched down the collar all the way and didn’t feel any drafts. There are few bags rated for -40 and below. But I purchased this one because of the gore-tex windstopper and the experience I have with Mountain Hardwear products.

Rated 1 out of 5 by from Wish I could give it 4 stars Last weekend I used this sleeping bag to hike the slopes of Bakersfield and it is clearly advertised it can handle -40C and I was absolutely freezing. Don’t buy this sleeping bag if you are trying to battle the elements like I do on a weekly basis. Not worth it for the money! Sincerely, Jacob

Rated 5 out of 5 by from Different league This bag is so warm and comfortable. I have slept comfortably in temps from 40 to -30. Have not tested lower yet. Dry inside even if outside is drenched in condensation. I would bivi in the snow with a tarp in this. Could use a pocket for phone.

Rated 2 out of 5 by from Toasty everywhere except feet I bought this about two months ago and I’m somewhat disappointed with its performance. Mountain hardwear is one of my favorite companies but the design of the foot box on this bag could use some touching up. I’ve used this bag for camping anywhere from 8 degrees F up to 40 degrees F and the foot box was always too cold. I have lighter down bags that don’t have this problem in the same temp so I know it’s not me. There’s no damage whatsoever to the bag, and the cut fits me just right so I’m not sure why it has this one cold spot. Definitely a bummer for the price, would probably return if I could but it’s already used now. I’m driving across the country right now so I’ve tested it in all different conditions, dry/ windy/ snowy/ moderate, and have had this problem regardless of weather. I don’t know if I would trust this bag in subzero temps, which is why I bought it. I even tried different weights of socks as well as no socks. I’ve tried tent camping, bivying, and car camping and they all have the same result. I’ve also tried my alpine sleeping pad as well as a foam pad. I’ve worked in an outfitter retail setting as well as an outdoor guiding setting for several years and I honestly can’t tell why this one product is having this issue.

Rated 5 out of 5 by from Toasty Warm Bag I bought this bag for Denali. I tested it out in 12F snow storm above Lake Tahoe the other day. I slept in a thin base layer and was toasty warm all night. I didn’t want to get out. I bought the long version even though I’m only 5-10. I wanted room to put things in there to keep warm. I’m glad I did that. I have no complaints s as bout this bag at all.

Rated 5 out of 5 by from So Warm! I have camped with this in temperatures around 10 degrees Farenheit, and was nearly sweating inside of it! such a cozy sleeping bag - definitely a good investment

Rated 5 out of 5 by from Wonderfully warm Extremely warm and comfortable bed. Cold bagged it with out a sleep pad at 15 degrees just to test it out. Perfect cut and length. Very happy.

Rated 5 out of 5 by from Wonderful This is a fantastic sleeping bag. Likely the best on the market. I bought it for below zero camping! Excellent service from Moose Jaw. Super soft.
