This multi-day backpack prioritises comfort, freedom of movement and easy access. Our improved patented Mammut Active Spine 3.0 adapts to the movements of your spine and distributes weight evenly across your body, while the mesh back maximises air circulation and keeps you cool. Important items such as water bottles are always just a hand's reach away thanks to the easily accessible mesh pockets and the removable integrated rain cover protects your equipment in wet weather. With the 70-80 litre Ducan Spine in a modern, technical unisex design, demanding stages will seem a lot shorter.
