Designed with the rigors of trail running in mind—but versatile enough for any outdoor pursuit—the Senja Warm1 Hood delivers breathable warmth and technical performance in a low-bulk, high-mobility package. Whether worn over a base layer or under a shell, it’s engineered to regulate temperature, wick moisture, and keep odor at bay, all while maintaining a featherlight feel.
Warm When You Need It, Cool When You Don’t
Built with Norrona’s warm™1 fleece, this mid-layer balances insulation and breathability. The 140 g/m² main fabric traps warm air efficiently, while strategically placed 127 g/m² mesh panels at the back and underarms promote airflow and sweat evaporation.
Anti-Odor, Pro-Comfort
Treated with HeiQ Fresh FFL, a silver-free, bio-based technology that targets sweat’s odor-causing proteins. The result: you stay fresher longer, even through long runs or multi-day treks.
Functional Trail Details
Features like the stretchy hand gaiters with thumbholes, a fitted hood, and a ventilating anorak-style front zipper are made for movement and layered flexibility—whether you’re cresting a ridge or powering through switchbacks.
