NOTE: This excellent pack has very small stains on the left hip-belt pouch, but otherwise looks new.

Sized for adventurous multi-day hikes, this pack prioritizes comfort, range of motion, and on-the-go access. Improved for maximum freedom of movement, the patented Mammut Active Spine 3.0 mimics your spine’s natural movement and distributes weight evenly across your body for a barely-there feel during uphill hikes. 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 50-60-liter pack makes carrying heavy gear long distances so much easier.
