Very warm bag
I got this bag on sale, and have since used it for a good amount of high altitude backpacking in Pisgah National Forrest (NC). Definitely a little warm to be considered a 3 season bag, but is nice and toasty during those long winter nights. Doesn't pack extremely small, but fits snugly into the bottom of my Osprey Atmos 65. I would recommend this bag for anyone who expects to be out in the back country with temps under 30.
