Marmot Helium 15F sleeping bag with 850 down, very lightly used and in like new condition. Weight is 35 oz. Bag is regular length which fits up to 6' tall persons. It has a left side zipper that is full length zipper. Including stuff sack and storage sack that came with bag. Used on only 1 trip and then I got a 3 season hydrogen bag and a quilt. Sleeping bag was too warm for the trips that I normally take. Sleeping bag always hung by loops when stored, and bag never compressed into a stuff sack. I packed it in trash compactor bag when backpacking. Selling for $220 including priority mail shipping to your door. If interested, send PM or email me at jeremy (at) marzani (dot) com.
