Haven’t used it yet

I gave it 5 stars but haven’t used it. Bought it for September backpacking in greater Yellowstone. It’s a little heavy but I needed a 15 degree bag that wasn’t crazy expensive

Great bag for the price

Just got back from a late season Colorado Elk Hunt. Temps were in the single digits at night. This bag kept me very warm and comfortable.

Great sleeping bag! Doesn’t fit my pillow or sleeping pad

Love the sleeping bag but the stretch portion designed hold you sleeping pad and the one designed to hold your pillow in place are too small. I have a long sleeping pad that is 78” and it doesn’t fit without a lot of craming and having to deflate the pad for it to fit. The pillow holder is for a pretty small pillow and doesn’t fit my hiking pillow at all. Besides that the bag is great and if you had a smaller pad and smaller pillow it would work perfectly!
