Awesome BAG

I purchased this bag a few years ago and have used it on many backpacking/hunting trips. It compresses very well to be easily packable and the comfort and warmth are everything I could have hoped for.

Light and warm

12000 feet with wind and i manage to stay comfortable.

Great sleeping bag!

Just spent 10 days in the backcountry of Colorado. Temps didn’t get much lower than 40 but the sleeping bag was great. I have bigger shoulders and was concerned about how roomy it would feel but I was pleasantly surprised! I wore gym shirts and a light long sleeve to bed every night and was very warm and cozy.

Love my sleeping bag

Quality made sleeping bag

I purchased this bag to replace my old 15 degree bag. This one packs smaller, feels less restrictive while inside, and lighter weight. Haven't had a chance yet to test it in the cold however, but I have no doubts at this point that it will perform well.
