Trion Spine 75L Backpack

You're taking your ski touring game to the next level, and like you, the Mammut Trion Spine 75L Backpack is destined for great things. Built with a tech-savvy suspension system, Active Spine Technology allows natural motions of the hips and shoulders without disrupting the load stability of the pack. What this means for you is complete freedom of movement over tricky terrain, all while maneuvering your way over glaciers and across scree with 75 liters of gear on your back.

In addition to plenty of room for all your gear and overnight equipment, the Trion comes with dedicated attachments for ice axes, trekking pole, rope carry, and reinforced side ski carry. A generous front zip opens your pack up fully for easy access when you're in your tent, while assorted pockets on the shoulder and hip straps ensure that small tools of the trade are never far from hand when you're on the go. The back panel features high-density, 2-layer EVA padding for comfortable carry, with padded hip and shoulder straps and an adjustable torso length guaranteeing a perfectly molded fit. The pack is hydration-compatible if you want to equip it with your favorite bladder, and it also includes a zippered side pocket for carrying extra water.
