Mountain Warehouse Everest Down Sleeping Bag

A good bag for what it says, lofts well, very warm. To Jo Bets, the bag is rated -11° comfort and -19° limit. If you use it at -3° you will sweat, fabrics are only so breathable. I have used it at -13° and found no problems. Get yourself a bag to suit warmer temps, say 2° comfort and -7° limit. I previously had one of their Everest models and 15 years on it's still usable. All in I've been outdooring for over 40 years. For the money it's good. Full review

Woods Canada Arctic 3 Star

I slept in this bag for four months in the Arctic and slept like a baby. Full review

Western Mountaineering Puma Super MF

Super WARM and very light... I have used this bag down to -15° and have been completely warm and comfortable. I have no doubt it would be OK even down to -25°, and I am a VERY cold sleeper. I usually need a bag that is rated at least 20 deg warmer than claimed, but not with this bag. When it is not too windy I often just sleep in an open lean-to or under a tarp, and am just fine in the middle of winter. The MF shell offers excellent wind and water resistance, zipper works great, there is plenty… Full review

Western Mountaineering Puma GWS

The Puma GWS lives up to the ratings and is high quality. The zipper works flawlessly and the cinch cord is easy to use. I slept out in -5 degrees with 25mph winds in a single person tent, warm all over. Remember a sleeping bag is only as good as its sleeping pad. In the winter you will get cold with any sleeping bag if you use a cheap sleeping pad. Full review

Wiggy's Super Light FTRSS

-4 degrees and as comfortable as could be. When you are outside in the cold and you know that everything is going to be OK, that's how I would describe this bag! This is the kind of bag you just can't wait to get into. Very warm (after about 15 seconds, then it warms right up). At -4 degrees it does everything I expect it to do. I'm a warm sleeper and most of the time it's unzipped. Packs great and puffs right up when you are ready to sleep. The bag is perfect for what I do, very durable heavy… Full review

Outdoor Vitals Summit 0

Backpacking in the winter can be discouraging if you don't have the proper sleeping bag. OutdoorVital's Summit 0° sleeping bag will keep you toasty with its down insulated properties, baffle design, hood, and overall comfort. In addition this sleeping bag packs down, weighs under 3 lbs, and most importantly, it's not overpriced! This sleeping bag has kept me warm on several nights in the teens. I haven't experienced any cold spots including around the zipper or hood. The fit is amazing. If you… Full review

U.S. Military Modular Sleep System MSS

It comes in three to four parts, where you can sleep in one part, two parts, three parts or four. I have slept in it all together and I had to open it up sometime during the night because I had gotten too warm. Come to find out it had gotten below freezing that night. I have also slept in just one part, the temp was at around 100° to 110° that night. Although it was hot, I was comfortable. Compresses down to about the size of a basketball, although it could probably compress smaller. Three to… Full review

Marmot Col MemBrain

Embrace the caterpillar in you! With this bag, I feel and look like a squashy green caterpillar. Zip it up, snuggle down, and after the coziest sleep in the coldest temps, you'll emerge in the morning a beautiful butterfly. That is if you can bear to come out! I'm a 5'4" smaller woman. I sleep cold and this bag works well for me in even the coldest of temps. I've still paired it with a liner for truly -20°F temps and that works well in a four-season tent.  Zipping all the way up can be a slight… Full review
