This backpack for multi-day hikes prioritizes comfort, freedom of movement, and easy access. Our improved patented Mammut Active Spine 3.0 adapts to the movements of your spine and ensures an even weight distribution. Essential items like water bottles are always just a hand's reach away, and the removable integrated rain cover protects your gear from rain. The women's model features a shorter back, and the shoulder straps are tailored to the female body shape. With a capacity of 50-60 liters, the Ducan Spine for women, equipped with a mesh back and modern technical design, makes demanding stages feel much shorter.
