Ull Backpack 30L – Lightweight Ski Touring & Alpine Hiking Backpack
Meet the Klättermusen Ull Backpack 30L — a lightweight technical backpack designed primarily for ski touring, yet versatile enough to perform as a year-round alpine hiking pack. With its 30-liter capacity, ergonomic carry system and adaptable compression design, it offers an excellent balance between technical mountain performance and all-season alpine versatility.
Built for movement and efficiency in demanding terrain, the Ull Backpack 30L combines a ventilated back system, dynamic shoulder mobility and practical equipment attachments for skis, trekking poles or an ice axe. Whether you're skinning up a snowy ridge in winter or hiking long alpine trails in summer, this lightweight pack keeps your gear stable, accessible and comfortable all day long.
Who is it for?
Ski tourers, alpine hikers and mountaineers who want a technical 30L backpack that performs across seasons. If your adventures include ski touring in winter, alpine hiking in summer or gear-intensive mountain days that require extra layers and technical equipment, the Ull Backpack 30L offers the ideal blend of lightweight design, organization and versatility.


What Makes It Stand Out
- Engineered for ski touring: Designed to carry avalanche gear and alpine tools, the Ull Backpack 30L performs confidently on half- or full-day ski tours.
- Versatile all-season alpine design: Thanks to its lightweight construction and ergonomic carry system, it also works exceptionally well for alpine hiking, trekking and climbing approaches.
- Lightweight yet capable: At just 798 g, it delivers strong mountain functionality while keeping the load light on long days.
- Ventilated ergonomic carry system: A padded back panel with ventilation channels improves airflow and comfort during demanding ascents.
- Technical gear attachment: External loop webbing and equipment holders allow easy attachment of trekking poles, skis or an ice axe.
The top-loaded drawcord system allows quick one-hand operation even with gloves, while compression straps help keep the load close to your back for better balance. A convenient side zip also provides fast access to essentials while moving in the mountains.
Compared with the more compact Ull Backpack 20L, this 30L version gives you more room for extra layers, avalanche gear and longer all-season mountain missions.
Why You’re Going to Love It
