Marmot Col MemBrain

rated 5 of 5 stars 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 -20F temps and that works well in a 4 season tent.  Zipping all the way up can be a slight challenge-… Full review

U.S. Military Modular Sleep System MSS

rated 4 of 5 stars Great first sleeping system (with two pads). Horrible for backpacking. I recommend the MSS to all my Boy Scouts. A used MSS paired with two foam pads is BY FAR the best value in sleeping gear. Here's what I give all my new Scouts (and parents): A synthetic-fill sleeping bag and two dimpled foam pads are best for most Scouts. Both are cheaper, rugged, easier to wash, and handle wet/dirty conditions better. Both can be used with better and/or cold-weather gear you can buy later. Consider first the… Full review

Wiggy's Ultima Thule

rated 3.5 of 5 stars For the price, this is a good bag, well-sewn and durable. It is roomy and comfortable and a pleasure to crawl into. I have an issue with my bag at temps under zero that I was surprised to find. The seam that is opposite the zipper side that runs from head to toe is very thin. Less than 1/4 inch of insulation can be felt along that seam. At 8 degrees below zero Fahrenheit, I experience a cold streak along this side of my bag. As mentioned above, overall for the price I am happy to keep and use this… Full review

L.L.Bean Down Sleeping Bag with DownTek, Mummy -20°

rated 4.5 of 5 stars A very good down winter bag with enough length to store stuff. Excellent warranty and excellent attention to details. I was looking for a -20° F down bag with DWR down treatment like Dri Down or Bean's Down Tek to ward off moisture collection over several days of winter use. Anyone who has winter camped with a down bag for a week or so knows the down gradually collects respiration and perspiration  moisture, losing insulative ability and making the bag heavier. DWR treated down like Bean's Down… Full review

Slumberjack Latitude -20°F

rated 2.5 of 5 stars OK winter outer bag, as long as you know how to sleep and survive in cold weather. Too big for a standalone bag for me. I used this bag last winter in northern MN while leading dogsledding/skiing trips as an outer bag combined with an old 15 or 20 degree down inner (probably actually 20-25° now) and spent around 40 nights out in it, in temps ranging from -25°F to 30°F. Slept on two Therm-a-Rest RidgeRests under open tarps, in a mid, or in a doglsed. As others have noted, probably not wise to… Full review

Mountain Warehouse Everest Down Sleeping Bag

rated 3.5 of 5 stars Bought specifically for Kilimanjaro (so generally expected dry weather). Did the job, but I won't be using it again as it didn't really survive washing afterwards (Kili is very dusty). Warmth: Never felt cold unlike some of my teammates. I did use it with an Exped inflatable mat, which I think made a big difference. Fit & Comfort: Pretty good, no scratchy bits. Found it most comfortable when worn with a base layer as has been mentioned it's not very breathable. Entry & Exit: ip is not very… Full review

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

Slumberjack Latitude -20°F

rated 5 of 5 stars Bag lives up to its name. People who contest otherwise are not dressing appropriately (overdressing) and should find other activities than outdoor ones. This bag keeps you warm. Some writers have indicated that it is overrated. ALL bags are rated for ideal conditions and are thus overrated for some activities. ALL. Bag is comfortable, loft holds up well. NOTE: you cannot overdress and use a bag that is designed for this low of a temperature. The more you wear, the more you will actually sweat. Sweat… 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
