Rated 5 out of 5 by from The Bag of Bags I bought this bag for using in the winter in Utah during my wilderness therapy stints. It is super warm, waterproof (to a point. If it sits in a puddle, after a few hours water will soak through), and actually packs down pretty well. My only complaint is it definitely doesn't fit in the stuff sack you're given. I just bought a Sea to Summit 30L waterproof eVent stuff sack and that did the trick. Plus it has those handy tightening straps to help compress the bag. The long is nice because you can put stuff at the feet you don't want to freeze. Just be careful though, the long is also a bit wider and you'll be cold if it's too big.

Rated 5 out of 5 by from One of the best investments I ever made! Let me start off by saying that I have owned this sleeping bag for at least 5 years and spent at least 100 nights in it. It has kept me toasty warm to below -40 through all of it and hss exceeded my expectations with many years of service left in it. I have always used a sleeping bag liner and on any longer trip I employ a "vapor barrier liner" to extend the duration the bag retains its loft and reduce its packed weight (in my case not as much a concern as packed size/ longevity of down). Durability is excellent for such a lightweight bag and it has withstood the compression cycles much better than any synthetic bag can . The waterproof/ breathable shell has made managing frost so much easier but it does make compressing the bag harder. Roll it into a huge roll and lean on it gently to force air out then quickly unroll and reroll, into the compression sack and start yanking/ squishing. I respect this bag so much that it is always stored layed out or hung and fully lofted.

Rated 5 out of 5 by from The best bag I've ever owned I've had my CWM -40F bag in service now for over 7 years and use it countless times each year in the high and cold altitudes of Colorado. I've used this bag innumerable times in temps in and around -10F and I never get cold. In fact, I hardly ever zip into the bag, usually just having it draped over me is more than sufficient even in very cold conditions. The loft has held up amazing well and I use it all the time. This bag is pricy but is worth every penny, and it will last and perform beyond expectations, that has been my experience thus far.

Rated 5 out of 5 by from A Bag for the Extreme Cold I purchased this bag last month and have been extremely impressed. Superb construction with attention to detail. Best loft I have ever seen in a sleeping bag. Highly recommend.

Rated 5 out of 5 by from A great bag indeed I have had this bag for 3 years and never cold in it, if anything I have the bottom zip open. Great for the snow and great for using outside the tent.

Rated 5 out of 5 by from This is soooooooo warm when it is soooooooo cold! I bought one for my Wife and one for me years ago and they still work great. These bags keep us warm if it is below zero and we really NEED to stay WARM! It is nice to have that security when you are miles from the car.

Rated 1 out of 5 by from Poor zipper choice, not warm enough I used this on Everest, and found that my 25yo Western Mountaineering bag was warmer than the Cwm. The small-gauge zipper often jammed, and rarely slide to the top of the track. Very frustrating in the middle of the night, particularly with temperatures that low.
