Klättermusen Tjalve 2.0 10L – Ultralight Daypack for Fast Hiking & Trail Missions

Meet the Klättermusen Tjalve 2.0 10L backpack — a minimalist, ultra-light technical daypack designed for fast-paced outdoor activities. Built for hikers, trail runners and minimalist adventurers, this compact pack keeps your essentials close to your body while maintaining exceptional comfort and ventilation.

With just 261 grams on the scale and a streamlined 10-liter capacity, the Tjalve 2.0 backpack almost disappears on your back while still carrying everything you need for short hikes, trail runs or fast alpine missions. Its breathable 3D mesh carry system and dynamic 4-S sternum strap system help stabilize the load and reduce bouncing — even when you move quickly over technical terrain.

Who is it for?

Minimalist hikers, trail runners and fastpackers looking for a lightweight performance backpack. If your ideal day involves moving quickly through mountain terrain with only the essentials, the Klättermusen Tjalve 2.0 delivers a precise fit, breathable comfort and durable eco-engineered materials.

What Makes It Stand Out

Ultra-light fast hiking design: At only 261 g, the Tjalve 2.0 is built for speed. It almost disappears on your back while carrying the essentials for trail running, day hikes or fast alpine missions.
4-S System® stability: Klättermusen’s innovative sternum strap distributes tension dynamically across the chest, helping reduce pressure points and pack bounce when moving quickly.
Highly breathable carry system: Soft mesh shoulder straps and a ventilated 3D-mesh back panel keep air circulating and help prevent overheating during intense climbs or summer trail sessions.
Recycled technical fabric: Built from durable Retina® Ultra polyamide using recycled Econyl® fibres and bluesign® approved materials for lower environmental impact.
Smart minimalist organization: Elastic cord system for quick external storage, two mesh pockets for essentials and hydration system compatibility for fast-moving outdoor missions.

Need to stash a wind shell during a climb? The front cord system holds it instantly. Carrying a soft flask or snacks? The mesh pockets keep them accessible without stopping. For short adventures where speed matters, the Tjalve 2.0 backpack keeps your gear organized without adding unnecessary weight.
