The expedition version of the Mission 55.  This is one of those awesome lightweight alpine packs that was designed for almost everything that the all-around Northwest mountaineer is looking to achieve.  A great choice for everything from standard overnight trips to 10-day mountaineering expeditions into our most remote peaks where you want the lightest weight reliable pack that is big enough to carry everything that you need, burly enough to handle some inevitable abuse, and still comfortable to wear fully loaded for hours on end in difficult mountain terrain.  From trails in the river valleys through ancient forests, through thousands of feet of horrendous punishing off-trail bushwhacking gaining the sub-alpine terrain and high alpine meadows, across snowfields and glaciers, and up ever steepening snow, ice, and rock to the summit of some faraway sought after peak.  The pack will comfortably carry all of your heavy gear in to camp with it's substantially padded waistbelt and internal framesheet, and then strip down to become the flexible lightweight summit daypack you need that gives you the freedom of movement that is necessary to climb the technical pitches to the top of the route. The lid and framesheet are both removable, and the padded portion of the hipbelt comes off to leave a fixed webbing belt.  Black Diamond's most durable alpine pack.  If you need a pack this big, you need a pack this big.
