Move faster, travel lighter, and stay focused in the hills with the Mammut Aenergy 18 Rucksack, a stripped-back, high-performance pack built for fast and light hiking.

Designed for pace-driven days in the fells, this ultra-light 18L pack keeps bulk to a minimum without sacrificing comfort. No skimp for storage, nonetheless, it boasts a roomy main compartment with a hydration sleeve and a large mesh outer pocket, two drop-in chest pockets, and a rolltop closure that adds another 2L if you need that little extra.

The breathable, ergonomic shoulder straps sit close to the body for a stable, bounce-free carry, while just enough back padding delivers comfort without weighing you down.

Built with primarily recycled materials and weighing in at around just 280g, this is a pack made for those who count every gram and every second.

Suitable for: Hiking, Via Ferrata, Mountaineering, Trail Running.
