Built for movement in cold, shifting mountain environments, the Lyngen Alpha100 Zip Hood is Norrøna’s most breathable insulated jacket—engineered for ski touring and high-output pursuits where temperature regulation matters as much as warmth. Light, resilient, and purposefully mapped, it balances wind protection with continuous airflow, keeping you comfortable from steep skin tracks to exposed ridgelines.

The lightweight aero100 double-weave face fabric delivers a refined blend of wind resistance, stretch, and durability, while remaining exceptionally breathable. Inside, Polartec® Alpha® insulation works dynamically: trapping warmth when you slow down and releasing excess heat the moment intensity rises. By body-mapping two insulation weights, the jacket delivers warmth where it’s needed most and resilience where packs and straps apply pressure.

Designed with a technical Y-cut and articulated arms, this jacket moves naturally with the body and layers seamlessly under a shell or stands alone in calmer conditions. Every detail is pared back, functional, and mountain-driven—built to disappear while you focus on the climb.
