The Second Light Vest is built for the power user who needs light and fast resistance to wind, chill and other inhospitable elements during long rides and runs. Its reMeridian™ stretch mini-ripstop fabric is constructed with 100% recycled nylon and treated with a highly weather-resistant PFAS-free DWR finish. The zippered chest pocket doubles as a compact stuff sack and reflective hits on the front and back increase visibility at dawn or dusk.
