Versatile, Lightweight Synthetic Warmth for Every Season

The Norrøna Men’s falketind thermo40 Zip Hood is the brand's lightest synthetic insulated jacket, designed to provide an exceptional warmth-to-weight ratio for year-round mountain use. Whether used as a breathable mid-layer during high-intensity ski touring or as a standalone outer layer for summer trekking, this jacket excels in variable conditions. Unlike down, the 40g/m² recycled polyester insulation maintains its thermal properties even when damp, making it an essential piece for unpredictable weather and high-output activities.

The exterior is crafted from aeroDownproof fabric—a 20D recycled ripstop nylon that is exceptionally windproof and durable while remaining soft to the touch. The technical fit is optimized for mobility, featuring articulated arms and a longer back cut for extra protection against the elements. A helmet-compatible hood with one-hand adjustment ensures you stay warm without sacrificing safety or visibility. Compact and resilient, the thermo40 is the ultimate versatile insulation piece for any mountain wardrobe.
