The Snowboards 18L Backpack from Jones Snowboards.
When you step into the side country or out the door of a heli you don't need to carry that much gear. The 18L pack is the perfect size for avy tools, water, snacks and an extra layer. Plus, its streamlined profile keeps your center of gravity tight to your body for a better ride. Rugged side and vertical board carry straps lock the board to your back when bootpacking - which is probably the only time you'll even notice the 18L pack on your shoulders.
