With a volume of 75 liters, the Trion Spine 75 is built to organize and carry a substantial load, which obviously begs a robust suspension system. No problem there!

Mammut's Active Spine Technology promises greater freedom of movement for the shoulders and hips, supporting a natural gait on the trail. Weight is transferred optimally as you walk, while the suspension system can be height-adjusted for a dialed-in fit.

A huge front zippered opening provides access to the entirety of the pack, while a large internal pocket, pocket on the shouler strap, internal zipper compartment, and pocket on the hip belt organizes your gear exactly where you need it. Lash your rope under the lid and your trekking poles or ice axes to the main body, while your skis attach to the pack's side.
