Today I purchased a REI sleeping bag from a neighbor. It is down and she said she thought it was a 0 degree bag. It is just over 7 ft long and weighs 4lb 10oz. (I weighed and measured it myself) It doesn't have a hood like a mummy bag, but it's mummy shaped. It has drawstrings and snaps at the top --someone explain those to me please--and it zips all the way on one side and has a short zipper on the other. Very clean, no rips or holes. I paid her $40.
