Underställströja Fjällräven Bergtagen Herr L

Fjällräven Bergtagen Woolmesh Sweater is a technical base layer built for demanding mountain days. It performs under a shell on ski tours, winter hikes, and alpine climbs, keeping warmth steady while moving moisture away when the pace picks up.

Using advanced body mapping, the sweater combines three different knits to balance insulation and breathability. Loftier, terry‑like zones across the shoulders, chest, and upper arms trap air for efficient warmth where you need it most. Along the sides, under the arms, and across the back, an open mesh construction boosts ventilation and speeds moisture transport during hard efforts. A smooth, rib‑knit collar, cuffs, and hem create a comfortable, flexible fit, and flat seams help minimize chafing—especially under a backpack.

The merino wool blend warms even when damp and naturally resists odors, while added polyamide and polyester enhance durability for long‑term use.
