Pack all your summer alpine equipment in Black Diamond's Mission 45 Backpack and then switch it out for ice climbing gear in winter. With swiveling SwingArm shoulder straps and a rotating ReActive hip belt, the Mission's suspension system allows easy mobility for more comfort on the longest of long approaches, and the ounce conscious alpinist can also remove the sturdy framesheet, top lid, hip belt, and fixed webbing belt to strip weight. The Mission is a traditional top loader with a drawcord skirt that protects your gear from wet weather. There's a sleeve behind the back panel for your hydration reservoir, and Black Diamond added a tuck away rope strap for extra convenience while climbing. Pick Pockets secure your ice axes, the front pouch protects the bag from crampons, and the zippered top pocket is perfect for valuables.
