Black Diamond M Mission Down 4000 m Parka

An expedition-weight 800-fill goose down parka built for mountaineers running cold-weather expeditions and high-altitude objectives, the Black Diamond Men's Mission Down 4000m Parka uses a proprietary liquid crystal polymer ripstop shell that resists tears better than the standard nylon ripstops on lighter down jackets. 800-fill power goose down at 90 percent down to 10 percent feather delivers the warmth that high-altitude basecamp and cold-weather belays require, and the LCP ripstop face fabric handles abrasion against pack straps, ice tools, and rope without down leaking through pinholes. A helmet-compatible hood seals over a climbing helmet for technical use, and the parka cut covers the upper hip for the added insulation that a cropped jacket does not provide. Sized at approximately 692 grams in size medium, the Mission Down 4000m sits between the Access Down 2.0 (midweight) and the Mission Down 6000m (expedition extreme) in BD's down progression, which is the appropriate parka for high-altitude alpinism and ice climbing where cold belays drive the layering system.
