This bag rocks!!!!!!!Review by Jbird
I've had this bag for years and just took it on my trip to Iceland (warm and toasty). Do yourself a favor and get one you won't regret it. (Posted on 12/20/2016)
Life-changing flexibilityReview by bzbert
When weight really counts, carry this and you won't need a parka, If you use a hammock in the cold, you won't even need a sleeping pad or underquilt. I've been using mine for 20 years - rock climbing, backpacking, running up to Everest Base Camp, and besides airing out, all it's needed is duct tape to keep down from escaping the wear points. If you're like me you'll use it as often as any piece of gear you own! (Posted on 10/3/2016)
