Women's Femund PureUll Long Sleeve 25/26

Built for long trail days, shoulder-season summits, and the quiet rhythm of everyday wear, the Femund PureUll Long Sleeve is a next-to-skin layer that feels as natural as the landscapes it’s made for. Clean lines and a refined silhouette make it as at home under a shell as it is paired with denim in town.

Crafted from Norrøna’s premium 100% merino wool, this midweight knit balances warmth and breathability with remarkable softness. The ultra-fine 18.5-micron fibers regulate temperature in shifting conditions—holding heat close when the air cools and releasing excess warmth as your pace picks up. Even when damp, merino continues to insulate, while naturally resisting odor over multi-day use.

The 165g/m² single jersey fabric is spun with S+Z twisted yarn for improved structure and resilience, giving the shirt a stable drape that maintains its shape through repeated wear. Durable for its class, the fabric stands up to abrasion, pilling, and snagging better than traditional wool knits—without sacrificing comfort.

A regular fit with articulated arms encourages unrestricted movement, whether you’re reaching for a hold, planting poles, or layering beneath outerwear. Thoughtful finishes like flatlock seams and a slightly extended back hem enhance comfort and coverage in motion.
