This is a hardly used, top of the line four season sleeping bag rated at -25F. It's a Mountain Hardware 5th Dimension which received the backpacker.com editor's choice award. It can open up extra on the side so that it can be used in warmer temperatures. This same bag sells for $270 new, so you'll save a good amount of cash for a bag that is in perfect condition and has hardly been used. I'm only selling it because I'm moving soon and won't be doing any winter camping anymore. I'm asking $200 obo, and shipping to anywhere in the U.S. is $20. E-mail me if you have any questions.
