Recent Cold Weather Down Sleeping Bag Reviews

Woods Canada Arctic 5 Star

rated 5 of 5 stars The warmest sleeping bag on the market. I used this bag in Northern Saskatchewan while working in geology. The temperature was minus sixty degrees Fahrenheit. I was cool, but at that temperature, what do you expect? This is the best sleeping bag I have ever owned. The sleeping bag is bulky, but will endure a lot of punishment. The bag can open up fully and be used as a comforter if necessary. This bag will keep you warm at -40 degrees. Full review

Western Mountaineering Bison GWS

rated 5 of 5 stars There's nothing wrong with a little overkill when you're serious about survival. I bought this bag two years ago for dead-of-winter camping in the mountains of East Tennessee and Western North Carolina. I wanted an overkill bag and decided to go all the way. The coldest temps I'm likely to see are maybe -10° on Stratton Bald. The coldest I have actually experienced was around 0° and this bundle of joy handled that with aplomb. I'm 5'9" and bought the regular 6 ft bag.  The zipper is well conceived,… Full review

Stephenson's Warmlite Warmlite Triple Bag

rated 5 of 5 stars Stephenson's Warmlite Triple bag is a top notch camping and backpacking sleep “system.” While an old design, it is still unique in the market, has a wonderfully comfortable mattress, and covers an extremely wide temperature range due to the dual tops design, for a price that is very attractive if you consider the alternatives. After many years, it was time to upgrade to a new sleeping bag and pad. One of my sons decided to “confiscate” my old cold weather sleeping bag and cold weather pad,… Full review

Ajungilak Goose Bay

rated 4.5 of 5 stars Good bag. I've spent approximately 400 nights in this bag so far, and have no complaints about anything but the zipper. It snags easily, and can be especially difficult to open when you're just waking up and trying to get out of the bag as soon as possible to escape the heat.  The included compression sack is also useless. I didn't like the design, and one of the straps broke the first week. Ajungilak replaced it, but I prefer using a traditional compression sack instead.  After 5 years of heavy… Full review

Big Agnes Crosho SL

rated 4.5 of 5 stars Warm, cozy, light, compact. Performs very well. I'm used to using two bags in Minnesota during the cold season since it often reaches -20° F here in the winter. Packing in two bags, two pads, and other gear gets heavy and bulky. I fill up my 95L pack. If I hike in a long ways, I normally pull my bag in on a sled. At a compact 4lbs 1oz (long), I can finally pack in on my back.   The bag repels water well. (I washed it after I bought it online. I hand kneaded water into it and it took forever… Full review

Black Pine Sports Backside Bside 800 Super Down -40

rated 1 of 5 stars Manufacturer's website claims the bag is filled with superior 800 down. Material tag on bag shows it is filled with 600 down (see photos on review). They have not explained why that is. Bag was returned. I stand corrected. One customer service employee said 800 is just a name. Strongly suggest they revise their website. Full review

Western Mountaineering Bison GWS

rated 5 of 5 stars Incredible quality in materials and craftsmanship. Packs down very small and is very lightweight (under 5 lbs) for its temp rating of -40F. I have no doubt it will live up to its reputation when put to the test. ***FEB. 3, 2015 UPDATE after field testing the Western Mountaineering Bison GWS****** So last night the temps got down to 23F here in Atlanta, so I set up my tent in the back yard and slept in the WM Bison GWS. WOW!!!  AWESOME BAG!!!! I have added a few photos to show the loft of the bag… Full review

The North Face Inferno -40F/-40C

rated 5 of 5 stars Excellent choice for winter camping, very packable for its size and true to its warmth. Have used it in a lean-to with no tent in miserable conditions and was quite comfortable. I have not slept out in -40° temperatures yet, but it was excellent at -20°. Closed up enough around the face to not freeze, actually ended up taking off my hat halfway through the night! A bit long for me, I'm 5 foot six, but I put extra clothes at the bottom. Easy to get in and out unless you are wearing lots of layers,… Full review

Woods Canada Mount Blanc Supreme

rated 5 of 5 stars I have owned this bag since 1980 when I purchased it new here in London, Ontario, for $200 at that time. This is a seriously warm and lightweight bag for its temperature rating as compared to my old eiderdown 3 Star bag which weighs in excess of 21 pounds. The Mount Blanc Supreme was the top of the line semi-mummy bag with 3 pounds of goose down fill and a nylon outer shell. Baffled construction and nice light green outer with yellow inner lining. It weighs in at about 4.75 pounds. Although a little… Full review
