Built for motion and made to adapt, the Senja Warm1 Hood is a lightweight mid-layer designed for fast-paced days on trail. It delivers a fine-tuned balance of warmth and ventilation—keeping you comfortable as intensity rises and conditions shift. Whether worn on its own in mild weather or layered under a shell, it’s a versatile piece that performs across seasons and activities.

The construction combines two recycled polyester fabrics to regulate heat and moisture with precision. The Warm1 knit provides efficient insulation without bulk, trapping warmth while allowing excess heat to escape. Lighter mesh panels through the back and underarms increase airflow and accelerate drying, helping maintain a stable microclimate during high-output efforts. Both fabrics are treated with HeiQ Fresh FFL, a bio-based odor-control technology that targets sweat residues to keep the garment fresher for longer.

Designed with movement in mind, every detail supports performance. The close-fitting hood layers smoothly without restricting vision, while the anorak-style zipper offers quick ventilation adjustments on the fly. Stretch cuffs with integrated hand gaiters add warmth when needed, and flatlock seams minimize friction over long distances. With a slightly extended back hem for added coverage and reflective details for visibility, this is a layer that works as hard as you do.
