Light, fast and technical, silky-soft Octa™ insulation delivers breathable warmth with minimal bulk for active mountain pursuits.

Designed for mountain pursuits that increase your heart rate and your motivation, the Dawner is dialed for active performance matched only by its go-all-day comfort. The secret? An interior fully lined from hood to hand pockets with silky-soft Octa™ insulation. Constructed in a slightly raised diamond grid pattern that holds in heat while allowing sweat to evaporate, it feels soft on skin and slides smoothly over a tee or baselayer. For dynamic mobility, the durable stretch outer moves with you and allows sweat to escape, with a DWR finish that sheds light precip. It can compress into one of its own lined, zippered hand pockets for easy stashing in a running vest or summit pack.
