We use a low air permeable, double-weave material treated with DWR to create a lightweight running vest that's protective against wind and light rain. The highly breathable fabric manages moisture and reduces wet-cling. It's designed for freedom-to-move run comfort that's easily packable. Thoughtful details include a two-way front zipper to adjust ventilation, reflective elements, and zippered hand pockets. Designed to protect you from cool wind without adding bulk, this ultralight windbreaker vest provides breathable, three-season run comfort without overheating.
