Castelli Summer Headband Sweat stays out. Helmet stays on. On hot days, sweat in your eyes is the kind of distraction that costs you focus when you need it most. The Summer Headband solves that with a polyester stretch front that pulls moisture away from your forehead, paired with a stretch mesh back that keeps airflow moving under your helmet. The raw-cut edge sits flat against your head without bunching, so it disappears once the helmet goes on. One size fits most, unisex. Polyester stretch front wicks sweat away from your forehead before it reaches your eyes during hard efforts Stretch mesh back opens up ventilation around the full circumference of the headband, reducing heat buildup under your helmet Raw-cut, trimless edge lies flat under a helmet without adding bulk or pressure points along the rim One size, unisex fit works across a wide range of head sizes without adjustment | Castelli | Summer Headband In White | Polyester
