The Mammut Trion Spine is an alpine backpack with a revolutionary back system: Mammut® Active Spine Technology™ ensures greater freedom of movement for the shoulders and hips together with even weight distribution. The back system adapts to the spine’s natural movements when walking and ensures more comfort on demanding ascents with a lot of equipment.

Two successful Mammut Pro Team Alpin athletes are impressed with the new packs:

Dani Arnold: ‘The Active Spine back system from Mammut feels completely different than usual backpacks. Especially the main straps are very comfortable while walking since they adapt to every movement of the body.’

Stephan Siegrist: ‘The new Active Spine back system is an excellent Development of Mammut and works impressively in practice.’
