Designed with trail runners in mind but versatile enough for any dynamic outdoor pursuit, this quick-drying mid-layer delivers breathable warmth where you need it and advanced moisture control where you don’t. Whether you’re climbing a ridgeline or navigating shaded switchbacks, the Senja Warm1 Hood keeps you dry, agile, and focused.

Constructed from two strategically placed fleece fabrics, the body uses a 140 g/m² 100% recycled polyester for warmth, durability, and sun protection (UPF 50+). High-sweat zones—like the back and underarms—feature a lighter 127 g/m² open-knit recycled polyester mesh with UPF 30+, enhancing breathability and ventilation without sacrificing performance. Both materials are treated with HeiQ Fresh FFL, a bio-based, silver-free odor control technology that neutralizes sweat-related smells by disrupting the bacteria's food source, not your skin.

Built for active layering, it features a close-fitting hood, integrated thumbholes with hand gaiters, a zippered chest pocket, and a mid-length front zip for quick venting on steep efforts.
