Mammut Ducan Spine Backpack

Active Spine Technology is a suspension system designed to mimic the natural movement of your spine as you walk. Instead of a rigid frame, the pack pivots and flexes with your gait, which helps keep the load balanced and reduces strain on your shoulders and back during long treks.

This is a dedicated women's specific design. The shoulder straps, hip belt, and back panel are contoured to better accommodate female anatomy, ensuring the weight sits comfortably on your hips rather than pulling on your shoulders.

Yes, the pack is fully hydration system compatible. It includes an internal sleeve and a port for your hose, making it easy to integrate most standard hydration bladders.

The material is water-resistant, but it is not fully waterproof. However, it comes with an integrated, detachable rain cover that you can quickly deploy if you get caught in a downpour.

The pack is designed for on-the-go access. It features easily reachable hip belt pockets for small essentials like snacks or a phone, and the layout allows you to access the bottom compartment without having to unpack the entire bag.

A 55-liter capacity is the sweet spot for multi-day backpacking trips. It provides enough volume for a tent, sleeping bag, and cooking gear, while remaining compact enough to stay stable on technical alpine terrain.
