Product Reviews

Rated 5 out of 5 by from My sleeping bag of choice! Definitely my sleeping bag of choice for high altitude or cold weather expeditions! After 30+ Himalayan expeditions and 25+ Antarctic expeditions this sleeping bag is by far my favorite. The combination of high loft for maximum warmth and lightweight yet robust materials make for a superior sleeping bag in the coldest and most extreme environments. The overall design and construction make the bag very comfortable. It wraps around my body so that I have enough space to move around, yet not too much extra room inside. The mummy style goes up and around my head, helping keep my head warm as well on those -40 degree nights! I highly recommend this product to anyone looking to explore or climb in the coldest places on the planet.

Rated 5 out of 5 by from Amazing sleeping bag So I have slept 75 nights in this bag at temperatures down to mind 30c and I never had a single cold night. I run survival courses in Sweden and have had many different sleeping bags over the years and this is by far the best. The gortex outer is amazing .. a little noisy but that’s to be expected. I love the size which means you can layer up if need be but I never have had to. Well done keep up the good work.

Rated 5 out of 5 by from Fantastic bag, kept me warm on Aconcagua This is a great, warm bag! I used it last week as one of my many tools to successfully summit Aconcagua [in 8 days!]. When it's compressed into it's stuff sack it is larger than my friends other brand bags, however, it's lightweight and crams well into the bottom of my pack. The zipper is strong. We got snow inside our tent at times, which melted, but the bag stayed dry (just a tad damp on outside is all). It's super puffy and comfy. I'm still able to turn onto my sides and sleep when lying on my back isn't working (I'm 5' 10' around 175). I got the longer one so I can put wet socks and inner-boots at the bottom when I sleep so they somewhat dry. With this bag, my little inflatable pillow, and buff over my eyes I had dreams I was sleeping at home in my own bed. At high camp on Aconcagua it was -20 degrees with 55kmh winds -- COLD! However, I never had a problem with staying warm while sleeping. Used this bag also at lower camps and it was very comfy -- instead of zipping it up I just used it like a quilt so I wouldn't overheat. Recommend this bag for any extreme conditions!

Rated 5 out of 5 by from Super cozy and true temperature rating! I got this item about a month ago, and since placing the order everything went perfect. The item was on back order but I received updates from the customer service team to inform me about it and they took action reaching out to their provider. Within few days I received the awesome bag!!! I also love the The customized packing that maintained the bag loose and safe during delivery. As soon as I try the bag in my backyard I could tell the quality, and how warm it was. The zippers show great quality and is nice and spacious, to have your booties at the bottom. Can’t wait to try it at Denali!

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
