Going new school, the
Mammut Shield 15 Degree Sleeping Bag is a waterproof shelter and 15-degree down sleeping bag rolled into one. It's essentially a waterproof sleeping bag. With no seams on top and seam-sealed stitches on the bottom, the roughly 2.5-pound Shield protects you from rain, snow and sub-freezing temperatures. It also has a stiffened visor that comes down to your nose to help keep you dry when you sleep.
