What Our Gearhead(R) Experts Are Saying:"The Lightweight Cap is the one I grab before any sunny run without a second thought. The perforated side panels keep airflow going even when the pace picks up, and the sweatband actually does its job so I stay focused on the run instead of wiping my forehead."Running into a bright morning means planning ahead, and the On Lightweight Cap takes care of the details so we can focus on the miles. Curved brim shading our eyes, perforated panels pulling air through on every step, it disappears into the run the moment we start moving. The On Lightweight Cap is built around a high-performance sweatband that pulls moisture away fast, keeping our focus where it belongs. A reflective On logo catches light on early or late runs, and the branded buckle closure dials in the fit without fuss. Made from recycled polyester throughout, it is a cap that moves with us through every season of training.
