Designed to keep you warm without compromising range of motion, our Skyfill Run Vest features the latest in insulation technology. We utilized a PrimaLoft® ThermoPlume® fill for its light, packable and water repellant qualities, and of course, to ensure the coSiest cold weather protection. Engineered with an elevated collar for blustery morning runs and reflective touches that provide 360-degree visibility, this adaptable vest snaps to our Skyfill Run Shrug to create the ultimate cold weather combo.
