Product details

Do you like to shift into a higher gear while hiking? Then you need lightweight and compact gear. The Lithium 20 is primarily made from recycled materials, and its permanently water-repellent coating is PFC-free. You’ll enjoy high wearing comfort thanks to the particularly lightweight and breathable shoulder padding. Air channels in the 3D EVA foam provide good cooling for your back. The padded hip belt features a fold-out pocket for your smartphone. If you don’t need it, you can simply remove it. The same goes for the integrated rain cover. The backpack is compatible with hydration systems. The side mesh pockets are also easily accessible while on the move. With the Lithium 20, you’ll be on the fast track in the mountains.

Trekking MagazinKaufberatung Wochenend-RucksäckeReleaseFebruary 2026

The alpine rucksack with variable length is perfectly balanced, moves with you and sits securely, but is less airy. Ideal for cooler temperatures and mountaineering to high altitude/ice tours, including hiking.
