The Mammut Pro X 35L Removable Airbag 3. 0 is a backcountry touring backpack that includes Mammut's ultralight, packable, and dependable Removable Airbag System 3. 0. Its bright orange airbag deploys via the height-adjustable handle and a compressed gas cartridge (sold separately). The airbag takes up little space inside the backpacks 35L capacity, and you can remove it for resort days. The pack itself is fully-featured for full days touring the backcountry or riding in-bounds. Mammut made most of it out of recycled material, and EVA padding adds cushioned comfort to the back panel, shoulder straps, and removable waist belt. The Pro X has external attachments for skis, snowboards, helmets, and ice axes, and internal compartments for a hydration reservoir, goggles, and avalanche gear. A full rear zipper grants easy access to the main compartment, even with skis or a snowboard on.
