Recent Cold Weather Synthetic Sleeping Bag Reviews

The North Face Dark Star -40

Warm. This is a warm bag. It was used on a 5-day trip to Ontario in temps that hovered in the upper negative teens F. When I did not roll off my pads, the bag kept me extremely warm. When not on the pads, it still kept me comfortably warm, but with a slight chill. Not at all uncomfortable. This bag is also quick to dry in the morning. These are the only positives in my opinion. The zipper is unbelievably difficult to pull closed the last 6 remaining inches. The draft tube comes loose easily… Full review

ALPS Mountaineering Echo Lake -20

A very warm and comfortable sleeping bag. While the Echo Lake -20 does the job, there are some things that could have been done better. I bought the ALPS Mountaineering Echo Lake -20 sleeping bag in October for dead-of-winter camping. Unfortunately we've had a very mild winter so far, and it wasn't until this past week that we've seen subzero temps. There's no sense in testing equipment if you're not going to approach or push the envelope, right? This past Monday and Wednesday nights were forecast… Full review

U.S. Armed Forces Modular Sleep System MSS

Personally test, constantly used, tough as nails! I have personally used this sleep system more than a hundred time, both while I was in service and now as a civilian. It was my first purchase (of military gear) the week I had to turn in my Army issued MSS, right before retiring. It's warm, tough/durable, and with the bivy bag it's water tight. Now, a lot of people complain about its weight (being around 10-12 lbs all together), but I am 6' 4" and 255 lbs, and I never even noticed when it was in… Full review

ALPS Mountaineering Desert Pine -20

A warm, but heavy, bag at an amazing price. Warmth (and conditions): This bag is rated for -20 and I've used it twice, once in the teens and once in the twenties, both times under the stars on my porch. I slept on a 2" self-inflatable air-mat and wore Polartec Powerdry expedition-weight base layer top and bottom, a Polartec Thermal Pro fleece jacket, a merino wool gaiter, a knit acrylic hat, thin acrylic gloves, and heavy wool socks. I didn't notice any drafts either time. The first time, the temperature… Full review

Wiggy's Super Light FTRSS

Worth almost every penny. I purchased this bag in January of 2012 to replace two bags (Eureka! 20 degree bag and Backside 0 degree bag) figuring that I wanted to do some Adirondack camping and would like the option to camp four seasons. At the time of purchase this system came with a free pillow made from the same material, but didn't come with its own stuff sack which wasn't a big deal, but would have been nice. The system was also on sale at the time, Wiggy's was having a sale that basically said… Full review

ALPS Mountaineering Crescent Lake -20

Warmth, compressibility. Definitely recommended. For any person planning a backpacking trip in early spring, late fall, hut ski trips, mountain climbing, camping, etc. I am an avid backpacker and needed a relatively lightweight, heavy-duty, cold weather sleeping bag. This one fit the bill perfectly. I live in Colorado, and the nights get very cold. This bag keeps you warm all the way to your toes. There is not a lot of moisture buildup. There may be some if it is slightly humid/ raining but not… Full review

Slumberjack Latitude -20°F

This is an overweight 30-degree bag imposing itself as a twenty below bag. I have never before seen such a mis-representation of a product without a company being sued or forced to recall its product. The problem is three-fold: Top has about 1" of loft, as noted by another reviewer (a -20 bag needs to bulge in the middle, not sag). Draft tube is not wide enough and not filled enough (it is a fairly-flat, 2" wide piece). Zipper catches and snags, not on the draft tube, but on the bag itself, ripping… Full review

Outbound Toaster 10000

This sleeping bag is great. Heavy duty durable zippers, and very warm.  Used it deer hunting in late November in Central Alberta for 4 nights.  Never had to get up to stoke the fire in the outfitting tent once.  I slept nice and warm though the night. I would recommend to anyone who wants a great quality warm sleeping bag for a fair price. Full review

U.S. Armed Forces Modular Sleep System MSS

Great value, flexible, a little heavy, but extremely durable. This system is exceedingly durable and very flexible. A huge bonus for this system is that depending on the conditions you can get by with either bag or both to cut down on weight. The bivy can almost be a tent in itself in a pinch. It is a little heavy and their are better performing lighter weight options available, but for the price this system is a very safe purchase that will perform reliably for years. Full review
