Many sleeping bags are rated for temperature by an independent testing protocol, the European Norm (EN) 13537. Each bag gets two ratings: a Comfort rating and Lower Limit rating. The Comfort rating is the lowest temperature at which the bag will keep the average woman (or "cold sleeper") comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep an average man (or "warm sleeper") comfortable. Everyone's body and sleep comfort is different, so EN Ratings are merely a guideline to help you compare products.

Rated 4 out of 5 by from Solid Sleeping Bag I'm very happy with the Sawtooth bag. It's kept me warm on several sub freezing nights. The loft is good and compression is fine as well. I find the baffle and hood to be well designed and easy to adjust. The zipper, like almost all bags I've owned snags occasionally, but not so often as to bother me much. It also works well as a blanket in warmer conditions. (although it doesn't unzip around the footbox, so it doesn't lay flat) It suits my fall, winter, spring camping needs well.

Rated 4 out of 5 by from Literally Saved My Life I purchased this bag several years ago but didn't use it initially for camping. I did use it a lot to drag my daughters around the house while they sat on it. I honestly abused it horribly doing that. Not only did it hold up to being used as a kids sleigh, it worked flawlessly once I began using it for my overnight hikes. Most recently (Oct. 1), I hiked to Upper Lena Lake in the Olympic National Park in the pouring rain. I was soaked from head to foot by the time I reached the lake (4,800 ft.) but the exertion from the climb had kept me warm despite the drop in temperature due to the altitude. But as soon as I had stopped hiking I felt the warmth leaving my body. By the time I found a campsite, set up my tent and got my wet clothes off and got inside my Sawtooth I was shivering uncontrollably. My Sawtooth quickly warmed me and after about 15 minutes brought up my core temperature so that I was no longer shivering. This was at 4:00PM and I was dreading the thought of what the night would bring but my Sawtooth kept me quite comfortable throughout the night. It compresses well, has more than enough room for my 5'9" frame. It also allows me to comfortably side sleep. Although I will probably buy a lighter bag with a higher temp rating for summer hikes, I have no plans to replace my Sawtooth for colder weather hikes.

Rated 5 out of 5 by from Nice bag I bought the wide bag and it is great. At 6'1", 275lbs, I needed a bag with extra room. This bag allows you to side sleep and is really warm. I have used it in 30 degree weather and it was too warm until I unzipped it. Well built, sturdy, packs small, great overall bag.

Rated 4 out of 5 by from Good all arounder Bought this bag a month ago in anticipation of some winter backpacking. I am a cold sleeper, a 5'9" male, 155-ish lbs. With decent thermals, a hat and wool socks I was toasty all through 14 degrees except for my toes! I used a TR neo air mattress and a tent, but as the temps got below the 20 degree mark my toes lost all feeling. I haven't tried any other brands and am not sure if I will, or maybe just get a warmer bag or liner. But, overall, at freezing and above the bag worked fine. Quality seems good and loft appears to hold just fine.

Rated 4 out of 5 by from Light weight and warm. I was stressing out about a sleeping bag after trying to stuff my military issue into a backpack. I thought I would never get one small enough, light enough, and warm enough to work for a tall frame without spending a fortune. I lucked out though. After recovering from some injuries, I was worried about staying comfortable and not over doing it, and this bag let me get a good night sleep. Used with an average inflatable pad in the high Sierras where temp was below 40. I might have been too warm. Can't say enough about this bag.

Rated 5 out of 5 by from Soft and Comfy The material is breathable and soft on the skin. I wouldn't suggest sleeping in anything less than long pants for fear of eventually sticking to it because I sweat a lot. The only bad thing is I have to fight my cats for it when I'm trying to pack it. It's that comfortable.

Rated 5 out of 5 by from great bag Packs small, good loft, experienced good warmth in the low 20's. Does what is advertised. Does not shed down like some bags I've owned. Would buy again but won't need to because of the quality of the bag.

Rated 5 out of 5 by from Military Approved Just got this for my boyfriend who is in the military and he absolutely loves it! Compacts really easily and lightens his load immensely. (Not to mention its crazy comfortable and cozy on a cold night)
