Klättermusen Skrymner Backpack 20L – Lightweight Fast Hiking & Trail Pack
Meet the Klättermusen Skrymner Backpack 20L — a lightweight technical pack built for trail running, fast hiking and alpine endurance missions. Designed to stay close to your body while moving quickly across rugged terrain, it combines ergonomic stability, breathable comfort and minimalist performance.
With its close-to-body carrying system, ventilated mesh shoulder straps and Klättermusen’s dynamic 4-S sternum system, the Skrymner keeps your gear stable and helps eliminate bounce even during high-intensity movement. Smart storage, hydration compatibility and mountain-ready functionality make it a dependable companion when speed and efficiency matter most.
Who is it for?
Trail runners, fast hikers, mountaineers and outdoor athletes who prefer moving fast and travelling light. If your adventures involve steep climbs, long approaches or technical mountain terrain, the Klättermusen Skrymner 20L offers the right balance between performance, stability and lightweight durability.


What Makes It Stand Out
- Designed for speed and endurance: Lightweight construction and a close-to-body carrying system ensure better stability when running, scrambling or moving quickly through the mountains.
- 4-S System® sternum strap: Klättermusen’s dynamic chest system distributes tension evenly across the chest, helping reduce bounce while maintaining comfort.
- Highly breathable carry system: Soft mesh shoulder straps and ventilated panels keep air flowing during high-intensity efforts.
- Smart performance storage: Elastic shoulder strap pockets, expandable front pocket and side bungee system give you fast access to essentials on the move.
- Mountain-ready functionality: Dual ice axe attachments, hydration system compatibility and protective lid construction keep your setup efficient on alpine missions.
Need quick access to snacks, gloves or a soft flask while moving? The elastic shoulder strap pockets keep essentials within reach. When the terrain steepens, the Skrymner Backpack 20L stays stable and close to your body, helping you maintain rhythm and efficiency on demanding trails.
Compared with a more classic hiking daypack like the Gilling Backpack 20L, the Skrymner feels more performance-oriented, more body-hugging and better suited to high-output mountain movement.
