Dedicated, durable and designed for ice cragging, mixed ascents and cold-weather expeditions, the Mission 55 is Black Diamond's toughest alpine pack. Featuring an updated BD X-rip 420d fabric with UTS™ coating, this pack is now ultra-durable to withstand season after season of mountain abuse.

　　The Mission also provides a balanced carry thanks to its SwingArm shoulder straps, and fully strippable waistbelt, lid and frame-sheet. The new custom metal dogbone ice tool attachment provides secure attachment for technical ice tools and mountaineering axes while a front crampon pouch and a tuck-away rope strap secure gear to the outside. Finally, a drawcord skirt provides a second defense against spindrift and light precip.
