Mission 55 Backpack
Tough enough for the most demanding alpine objectives.
The Mission 55 Backpack is Black Diamond’s toughest alpine pack, dedicated to ice cragging, mixed ascents, and cold-weather expeditions. This workhorse balances the load-hauling comfort needed for the approach with a strippable design that sheds weight for the technical push to the summit. With a suspension system that moves with your body and dedicated storage for tools and crampons, it streamlines your transition from base camp trekker to vertical climber.
