Achieve top notch warmth in the REI Radiant +0degF down sleeping bag. For cold-season backpacking, this bag is designed with comfort and weight savings in mind. 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, wrap-around draft collar and full-length draft tube with ground-level seams keep body heat in and cold air out. The REI Radiant +0degF down sleeping bag has an external chest pocket that stows your watch, glasses or other small essentials. Differentiated drawcords (1 round, 1 flat) let you adjust hood and neck easily in the dark. Full-length of zipper is backed by wide, antisnag binding tape. 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). Includes stuff sack and cotton storage bag. European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags.
