The Soelden 25 backpack is a compact technical ski touring pack designed for fast and light trips into off-piste terrain, where every gram and every second counts. Its well-thought-out design combines low weight with maximum functionality, making it an ideal companion for demanding ascents in a mountain environment.
Thanks to removable components, a LightWire frame and durable NanoFly™ fabric, the Soelden 25 offers an exceptional balance between stability and lightness. A dedicated avalanche-gear pocket ensures quick access to rescue equipment exactly when it matters most.
- Lightweight construction for efficient movement in the mountains
The 2.5 mm LightWire frame together with a moulded EVA foam back panel provides stable, energy-efficient load transfer, while the gender-specific harness and an adjustable sternum strap with safety whistle allow precise adjustment to each user’s anatomy, significantly reducing fatigue even on long ascents. - Snow-specific features for safe backcountry use
The backpack is equipped with a snow-shedding back panel that prevents ice and snow build-up, and offers multiple ways to carry skis—diagonal or A-frame—as well as horizontal or vertical snowboard carry, so it easily adapts to different winter mountain sports disciplines.
