Mammut Ducan Spine

Active Spine Technology uses a flexible suspension system that moves with your body as you walk. Instead of the pack remaining rigid, it adapts to your natural gait, which helps keep the weight stable and reduces strain on your shoulders and hips during long hikes.

Yes, this model is tailored to the female anatomy. It features a shorter back length and contoured shoulder straps designed to sit more comfortably on a woman's frame compared to unisex or men's packs.

While the pack features a rolltop closure at the top, it also includes a full-length front zipper. This allows you to open the main compartment like a suitcase, giving you quick access to items at the bottom of the pack without having to dig through everything from the top.

Yes, the pack is fully hydration-system compatible, so you can easily integrate your own reservoir for hands-free drinking on the trail.

Yes, it includes an integrated, detachable rain cover. It is tucked away in a dedicated pocket, so you can quickly deploy it if the weather turns while you are on the trail.

Yes, the hip belt features a fold-out cellphone pocket. It is designed to keep your phone accessible and secure while you are on the move, so you don't have to take the pack off to grab it.
