DESC: Stay warm on cold-weather climbing, backpacking or mountaineering trips with this feature-packed 800-fill goose down wide mummy bag. Premium-quality 800-fill-power goose down is extremely compressible and offers exceptional warmth-to-weight. Water-repellent, windproof, downproof 20-denier nylon shell is lightweight, yet strong. Six-Baffle Hood envelopes your head in warmth, while the Face Muff allows hood to be cinched snug without digging into your face. Down-insulated draft collar and draft tube backing the locking, two-way full-length zipper seal cold out; zipper guards prevent zipper snags. Ground-level side seams eliminate cold air leaks. Spacious footbox allows down to loft fully around your feet for optimum warmth. Stretch tricot baffles provide strength and durability for a longer life to your bag. Includes nylon stuff sack and cotton storage sack.
