The Norrona Femund Warm2 1/2-Zip Jacket is right at home trekking across high mountain meadows and kicking it on the couch, keeping us comfortable no matter the occasion. The warm, breathable Polartec Microfleece helps regulate our temperature, and the half-zip allows us to customize airflow to stay cool during grueling climbs. Thumbholes provide some extra warmth around our hands and keep our sleeves in place as we swing our trekking poles for extra power.
