Mammut Ducan Spine

The Active Spine 3.0 is a suspension system designed to mimic the natural movement of your spine while walking. It allows the backpack to flex and rotate with your body, which helps distribute the load more evenly and reduces strain on your shoulders and hips during long treks.

The capacity is adjustable. The '70-80' range refers to the pack's ability to expand, typically via a rolltop closure, allowing you to compress the bag for lighter loads or extend it when you need that extra 10 liters of space for longer expeditions.

Yes, the pack is designed for accessibility. It features a large front zipper that opens the main compartment, so you don't have to dig through the top to find items packed at the bottom.

Yes, the Ducan Spine 70-80 is fully hydration system compatible, allowing you to easily integrate a water reservoir for hands-free drinking while you hike.

The pack features a dual-forward-pull hip belt adjustment system. This allows you to cinch the belt tightly and evenly, ensuring the weight is effectively transferred to your hips rather than hanging on your shoulders.

Yes, the pack includes strategically placed mesh side pockets designed specifically for on-the-move access to water bottles, so you don't need to stop or ask a hiking partner for help.
