Klättermusen · Skrymner Backpack 20L
The pack that keeps pace, even at a run.
The Skrymner 20L sits close to the body, like a vest: mesh shoulder straps with pockets for a soft flask, a four-point sternum strap, straps anchored at several points so nothing bounces. A lid covers the opening, the front pocket takes your jacket, the side cords your poles.
Trail running · Fast hiking · Mountaineering
The approach at a jog, the ridge there and back, the outing before work.

Klättermusen was founded in Umeå, Sweden, and has made mountain packs since 1975. Its packs have been made of recycled polyamide since 2009.
Klättermusen repairs zips, seams and buckles. Outside the guarantee the service is paid, on quotation; Eiken passes the request on.
Empty it and let it dry after the outing, hand wash with a mild soap, reproof if needed.
Eiken's take
- Our pick
- It wears like a vest: mesh shoulder straps with pockets, a four-point sternum strap, straps anchored at several points. For moving fast in the mountains, this is the harness you want.
- Worth knowing
- It is made to carry light: with no padded hip belt, the weight stays on your shoulders. For a loaded day, the Gilling 20L is more comfortable.
- Who it's for
- Mountain runners and fast walkers, with a jacket, water and something to eat.
