Move around the campsite with ease in your Mobile Mummy sleeping bag from Sierra Designs. It's designed to move when you do, so you can sleep on your side, stomach or back without feeling constrained. The best part - you can wear this bag like a garment. Sit up and use your hands to grab a drink or snack, then stow the foot box for a stroll around the grounds. The zipperless armports have no hard closures to get in your way, and the ultralight toggle-free hood fits around your face like your favorite hoodie. Available in DriDown and Synthetic versions. Outside Magazine gave this bag the Gear of the Year award.
