REI Kilo Flash +40 Sleeping Bag - Regular

This ultralight 40° F goose down bag is cozy and extremely compressible. Premium 750-fill-power goose down is efficiently distributed for maximum comfort with 60% of the down on top and 40% on the bottom. Tightly woven, lightweight ripstop polyester and soft taffeta lining are silky, breathable and downproof. Vertical Baffle construction allows the goose down to remain fully lofted and keeps it from shifting and migrating, preventing cold spots. Vertical Baffles also prevent down from shifting to the sides and keeps more down on top of the bag where it keeps you warmer. In-The-Round construction wraps vertical baffles around from head to foot creating a three-dimensional tube that surrounds you in warmth. Differentiated drawcords (one round, one flat) let you adjust hood and neck easily in the dark. Pad loops provide attachment points to keep your sleeping bag and pad together to avoid rolling off onto the cold ground (straps sold separately). Roomy hood and footbox, full-length draft tube and draft collar keep heat in, cold out. Hood's spacious design lets you comfortably place a pillow inside without the hood becoming too tight. Efficient slim cut keeps the weight down. Internal pocket keeps watch, glasses and other small essentials handy. Includes stuff sack and large cotton storage bag.
