Anatomically designed for women, this version of the Ducan Spine 55 provides unmatched carrying comfort. The innovative Mammut Active Spine Technology™ moves in balance with the body’s movements and more evenly distributes the backpack’s weight across the body for excellent freedom of motion, which helps reduce fatigue. Meanwhile, the air space suspension system improves comfort with its effective back ventilation. Shoulder straps, carrying system, hip belt and back dimensions are specially tailored for women. The hip belt has side pockets positioned for easy access while walking, and an oversized front zipper opening guarantees easy packing, all making the Ducan Spine 55 a super practical and functional hiking backpack.
