Gone are the days when you have to choose between bringing a pillow or extra clothes into the backcountry, not when you've got the Hyperlite Mountain Gear Stuff Sack Pillow in your gear closet. This nifty stuff sack keeps your clothes organized by day, and turns into a comfortable pillow by night. A fully waterproof construction, complete with sealed seams and a waterproof zipper, keeps your clothes dry in case you get caught in a storm. The sack is reversible, though, and on the other side you'll find plush Polartec fleece. When it's time to hit the sleeping bag, reverse the sack and experience a comfortable night's sleep with the cozy fleece against your face.
