Designed to keep you moving through shifting conditions, the Senja Warm1 Hood is a streamlined mid-layer built for high-output efforts. Lightweight, breathable, and quick to dry, it delivers just enough warmth to take the edge off cool air without slowing you down—ideal for trail runs, fast hikes, and everyday outdoor pursuits.

The construction pairs two recycled polyester fabrics to balance insulation and ventilation. The primary Warm1 knit traps heat efficiently while maintaining an excellent warmth-to-weight ratio, while lighter mesh panels under the arms and across the back increase airflow and accelerate moisture transfer. Both fabrics are treated with HeiQ Fresh FFL, a bio-based odor control technology that targets sweat residues to keep the garment fresher over extended use.

Every detail is shaped for movement and adaptability. The close-fitting hood layers easily without bulk, and the anorak-style zipper allows for precise temperature control from both ends. Stretch cuffs with integrated hand gaiters provide added coverage when needed, while flatlock seams reduce friction over long distances. Finished with a slightly extended back hem and reflective details, this is a piece built to perform from first stride to final mile.
