Wraith™ -20°F / -28°C Sleeping Bag is rated 4.9 out of 5 by 13.
Rated 5 out of 5 by from Great Bag! This sleeping bag is bomber, and packs down surprisingly small for having a shell. Compressing it, I am able to fit it in the bottom of my 65L Gregory pack just fine and still have room for all of my other gear that needs to go in. The added weight, when comparing competitors' bags of similar fill power and temperature rating, definitely comes from the shell, but I wouldn't trade that for anything, as it can double as an emergency bivvy out in the elements and also saves the down from getting wet if there is a condensation problem within the tent. The materials used for the shell feel very durable, and even though I am still careful with it to keep from tearing anything, I don't feel that I necessarily NEED to be super careful. I have not had a chance to test it at or below 0 degrees yet, but have used it a few times in below freezing temperatures (with proper sleeping pad insulation and a 4-season tent) and was very comfortable. I will throw in a disclaimer that I am a very cold sleeper, so with mid-weight merino top and bottom, a hat, thick socks and down booties, and a couple of hand warmers tossed in, this bag provided amazing warmth for a frigid little person such as myself and I would be 100% confident taking this on a trip where the temperatures dipped below 0 degrees. Being only 5'3", however, I was surprised at how small this bag felt. It claims that the interior length for the Regular is 78 inches (fit for a 6'6" person), but I feel there is significantly less wiggle room than what is listed on the spec sheet. I was still able to put a couple bulkier things at the bottom of the bag to keep them from freezing, but definitely not 15 inches of room as advertised with regards to my height. A coworker of mine, who is 6'0", ordered the Long after hearing my feedback and agreed that the bag feels smaller than it should. So, my recommendation would be to size up if you're on the cusp of the Regular's height recommendation. Not that I'm complaining, personally, because that's less dead space for my body to try and warm up since this bag doesn't come in any shorter sizes, but just throwing that out there as a general warning to anyone considering purchasing this sleeping bag. The only thing that could make this bag even better than it already is would be to push the fill power to 850+ for weight and space savings, but that's a minor critique. I have been extremely happy with my purchase and look forward to more winter backpacking trips with it! Job well done, Mountain Hardwear!

Rated 5 out of 5 by from Just Right I've used the Wraith on K2, Everest and more. I find it the right combination of weight, warmth and comfort. Highly recommended.

Rated 5 out of 5 by from Worry about other things There is a lot to think about when going into the mountains, and the last thing I want to worry about is being cold at night. This bag is insanely warm and lofty, but packs down to the size of a normal high end 0º bag. There is plenty of room inside of the bag to place "extras," such as puffy layers and ski boot liners. The pull cord and inner cuff work wonders- The photo was taken after waking up with no tent after a 10ºF, 60+mph wind night. I will continue to use this bag and have peace of mind on my future adventures.

Rated 5 out of 5 by from Bought it again I used this bag as my primary bag on successful summits of K2 and Annapurna I. When my sleeping bag and down suit were in a bag that got lost by an airline, I didn't hesitate to buy them again for an upcoming expedition on Kanchenjunga. This bag strikes the perfect balance of weight, internal room, weather resistance and cost. It is roomy enough inside to wear a down suit inside the bag. No need for a -40°C bag in the Himalayas. I've used in Alaska and other pretty harsh environments and love it.

Rated 5 out of 5 by from Great All Around Winter Bag I first started looking at this bag because not only did I need a warmer sleeping bag but I also plan on venturing to colder and colder climates as I gain more experience. I also wanted something that would keep up with my ambitions and not force me to purchase another piece of gear down the road. The saying goes.. buy once, cry once.. right?! Since we all know this bag can take us well beyond it's lower limit of -20°, how about some info on it's upper limit? I did a lot of research before buying this bag and one thing I had a hard time finding was the bags upper temperature limit. Since I don't live in a sub zero climate I decided to try the bag out without a tent on a night in the upper 30's. With just a z-lite sleeping pad, the bag and base layers on I was very comfortable in my bivy. I used the lower zipper to vent the bag a bit after getting settled in but after that I dont think I moved an inch all night. I'd have to say it was one of the best night sleep outdoors I've had in the winter. So if your looking for one winter bag to do it all from 30° to - 40° I would highly suggest the Wraith.

Rated 5 out of 5 by from Down for Days Got me through a utah winter with winter temps as low as -10F- used 1 season and counting - could not ask for a better winter bag. I'm 5'2 115 lbs and the size (reg) is perfect for me.

Rated 5 out of 5 by from Crazy high loft, absolutely the best quality down and shell! The 2 1/3 pounds of down fill creates a solid 10 inches of strong loft which is insanely warm and so soft. Long is perfect for me at 6'1" and 210 LBS. Winter Mummy cut has much more mid-leg width which allows spreading of your knees and more arm room with arms at the side than performance cut. Great balance of space and efficient cut. Outer fabric is light and as waterproof as any jacket. Its a great shell. The new generation zipper is much less snag prone than the older bags due to a great two inch zipper liner sewed on both sides. Works great. Absolutely perfect in my opinion other than the pull cords in hood are long and can be touch your face. All this and you can compress it to fit in the sleeping bag section a 65L pack and is only 4.7 LBS. Pare with a good bivy sack and fancy down pad and you are ready for real cold.

Rated 5 out of 5 by from Excellent Bag I have been a down sleeping bag person for over 40 years and 20 years ago I bought my first Gortex down bag. I am a firefighter and my bags get put in a very rigorous environment. I knew when it came time to replace my old bag I wanted another similar to it. The Wraith is absolutely fantastic, the fit, the durability, the new tech waterproofing, on a one to ten scale 15+ . I am extremely impressed.

Rated 5 out of 5 by from Awesomely warm bag I purchased this bag for Aconcagua this year with the hope that it would also prove up to the task for Denali next year. Overall this bag is awesome. Too hot for the approach (as would be expected) but full side zip made things bearable. It was so cold and windy that we were stuck in our tents for a whole day at our 19,000' camp and I was warm and toasty. I definitely believe this bag will be warm enough for Denali. Included stuff sack is nice. Only minus would be that this bag is a little heavy. I'm 5'8" and had plenty of room to stuff my liners and some other goodies with plenty of room.

Rated 5 out of 5 by from Great expedition bag I have used this bag in some pretty extreme temperatures and its performed great. Its kept me warm on backpacking and ice climbing trips in northern minnesota in the dead of winter, reaching temps well below the rating of -20F and winter nights on a portaledge and it kept me warm. i also used this bag on a 22 day expedition on Denali. I regularly slept with my ipod, camera batteries, .5L thermos and inner boots to keep them all warm and had plenty of space. for reference i am 5 10 160b and purchased a regular.
