Mammut Ducan Spine 28-35 L backpack 2025

Sized for day hikes and minimalist multi-day trips, this pack prioritizes comfort, range of motion and on-the-go access. Improved for maximum freedom of movement, our patented Mammut Active Spine 3.0 mimics your spine’s natural movement and distributes weight evenly across your body for a barely-there feel. The ventilated back system encourages air flow to keep you cool. Easy-access mesh pockets keep water bottles and high-use gear within reach, and an integrated, detachable rain cover seals out wet weather. With its progressive and technical look, the unisex Ducan Spine 28-35-liter pack makes carrying gear long distances so much easier.
