Rated 5 out of 5 by from Great sleeping bag! I've had this bag for about a year now and I love it! It's very warm and light. For it's maiden voyage I took it to over 9000ft in late June. Overnight the temperature dropped to below 25F and I was toasty warm. I actually had to sleep part of the night with one arm/shoulder hanging out of the bag. Everyone else was freezing...
