When going light can make all the difference, the Exped Wallcreeper PL 40 Degree Sleeping Bag is one item youll want to throw in your pack. This multi-purpose sleeping bag is the ultimate chameleon. You can wear it cinched around your waist as a parka, extend it full length for lounging around camp or quick bivying with your boots on, or zip it open as a comforter/blanket. When its time to bed down, close everything up for the ultimate ultra-light sleeping bag. Zippered armholes give you convenient out of bag access for melting snow and sorting gear without leaving the comfort of your bag. A lightweight ripstop nylon shell, with efficient PrimaLoft Sport water resistant insulation, completes this versatile three season comfort system.
