Forgive me, but when this beautiful thing became available on Gear Swap, my brain went dead and my heart soared.
I must show off the ultimate piece of cold-weather gear, rated down to -10 F in this case. cinched up, it can be worn as a coat during the hike. Lower the skirt, and you can wear it around camp. In full sleeping bag mode, you are utterly cocooned. (I know I'm in there someplace).
One disadvantage, per the old Christmas Story movie: I can't put me arms down.
P.S. Anybody caught laughing will be . . . . Well, no. It is pretty funny looking. Go ahead.
