REI Kilo Expedition -20 Sleeping Bag - Long

With smart goose down insulation distribution and a waterproof shell, this cold-weather bag is warm, weatherproof, and very compressible. Goose down is efficiently distributed for maximum warmth and comfort—800-fill-power goose down on top and 700-fill-power goose down underneath. Ultralight nylon shell features Gelanots® waterproof, breathable coating for superior weather protection. Vertical Baffle construction lets the goose down remain fully lofted and keeps it from shifting and migrating, preventing cold spots. Vertical Baffles also prevent down from shifting to the sides and keep more down on top of the bag where it keeps you warmer. Exclusive dual Regulator zippers adjust temperature as needed—fully close both zippers to increase warmth, open inner zipper to decrease warmth. Multi-chambered hood and contoured, insulated draft collar seal in heat; trapezoidal foot box increases comfort and provides more space. Relaxed fit from hip to knees increases comfort by providing space to move around in. Includes nylon stuff sack and large cotton storage bag.
