This exceptionally lightweight fleece jacket (244g in size M) is engineered for mountaineering but excels in a variety of activities, from trail running to ski touring, thanks to its outstanding breathability and moisture management.
Crafted from Polartec® Alpha® 120, this jacket offers an optimal balance of weight, warmth, and compressibility. The advanced fabric ensures efficient warmth without bulk (120 grams/m²) and features superior moisture-wicking properties.
To enhance mobility and reduce fabric mass where it counts, Norrona incorporates Polartec® Power Grid fabric (97% polyester, 3% elastane, 139 g/m²) in high-stretch areas such as under the arms, down the sides, and around the hood. This stretchier material complements the Alpha® insulation with superior flexibility and breathability, providing a tailored fit that moves with you.
