Best way to strip weight on your next run? The Vantage Air Cap: A mostly-mesh construction that gives you superbly breathable venting, with just enough of a brim to keep the sun off your face. The sweatband has our proprietary ActiveIce™ technology, which uses your own sweat to cool you down. A super easy shock cord adjuster means you can loosen or cinch up your sizing with a single hand, and a reflective logo keeps you seen during dawn and dusk missions.
