Ultralight, All-Season Synthetic Insulation for High-Mountain Mobility

The Norrøna Women’s falketind thermo40 Zip Hood is the lightest synthetic insulated jacket in the Norrøna collection, engineered for those who move fast and light in the mountains. Whether you are using it as a standalone outer layer on a brisk summer morning in the alpine or as a high-performance midlayer during winter ski tours, the thermo40 provides an exceptional warmth-to-weight ratio. The exterior is crafted from aeroDownproof 20D recycled nylon, a ripstop fabric that is windproof, soft to the touch, and treated with a PFC-free DWR to shed light moisture.

At the heart of the jacket is 40g/m² thermo40 recycled polyester insulation. Unlike traditional down, this synthetic fill retains its loft and insulating properties even when wet, making it the ideal choice for unpredictable weather or high-intensity activities where moisture management is key. The technical fit is enhanced with articulated arms for total freedom of movement and a longer back cut for extra protection. With its helmet-compatible hood and minimal pack volume, the falketind thermo40 is a versatile essential that belongs in every mountaineer's year-round kit.
