Designed for active mountain pursuits, the light and fast Dawner's silky-soft Octa™ insulation delivers breathable warmth with minimal bulk.

With mountain performance matched only by its go-all-day comfort, the Dawner is the ideal high-performance, low-profile insulator for chilly trail runs, late-season ski tours and any cold-weather pursuits that up your heart rate. 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.
