Marmot CWM sleeping bag. -40F/-40C, regular length, right zip. Bag is in great condition. I used it on 3 research expeditions in Greenland, and it seems that that phase of my life is over so it is time to get rid of it. The last time I used it I was definitely toasty at -30. It has been stored in its cloth storage sack. I always used a liner in it, and it will be cleaned professionally before it gets to you. I will also include an OR compression sack that it fits in. I prefer local pickup/meet up in Seattle region but willing to ship (buyer pays shipping). $420
