  • Features

    • High-quality 650-fill-power goose down is warm, lightweight and compressible
    • Relaxed fit from the shoulders to the hips increases comfort by providing ample space to move around
    • Exclusive REI Down Fill Calculator optimizes the amount of down per baffle for the most warmth with the least amount of down
    • Baffle spacing allows the down to remain fully lofted and keeps it from shifting, preventing cold spots
    • Equally distributed insulation all the way around the bag accommodates the multiposition sleeper
    • Ripstop nylon shell resists water and abrasion; smooth taffeta lining is comfortable against your skin
    • Shell fabric is treated with a Durable Water Repellent finish to repel moisture and stains
    • Contoured hood, insulated full-face muffler and full-length draft tube with ground-level seams keep body heat in and cold air out

    • Differentiated drawcords (1 round, 1 flat) let you adjust hood and neck easily in the dark

    • Any REI backpacking bag can be zipped to any other REI backpacking bag because of the consistent 63 in., No. 5, YKK zipper; women's bags zip on the right, men's on the left
    • Pad loops provide attachment points to keep your sleeping bag and pad together to avoid rolling off onto the cold ground (straps and sleeping pad sold separately)
