New, never used, tags still on Marmot CWM MemBrain -40F goose down sleeping bag. Super compressible because of the goose down insulation. Left hand zip (made for right-handed people). Baffle to protect against drafts. Small zippered pocket near top of bag by zipper. Includes sleeping bag, loose mesh storage bag, and stuff sack (everything it came with). I bought this at the same time I bought Marmot’s -20F bag for winter camping with my wife. She gets cold, so I figured she could use the -40F and I could use the -20F. She never went with me when it was cold enough to use this. This bag is great for really cold winter camping, winter/high altitude mountaineering, etc. Weight: 4lbs 8.89oz. Shell: 100% nylon Pertex Shield waterproof/breathable fabric. Insulation: Certified 800 fill power goose down.
