On days when temperature or planned effort mean a full head cap would be stifling but just wearing a helmet would leave your ears out in the cold, nothing beats Hincapie Sportswear's Power Headband. It offers thermal coverage over the ears without impeding your body's ability to ventilate naturally through the top of your head, where the preponderance of surface level blood vessels helps you dump excess heat generated by your legs and core. For cold weather rides, this sort of ventilation can keep you from overheating on climbs, sweating profusely, and freezing on the way home. The Power Headband is made of Hincapie's BodE Thermal Heat, the manufacturer's most insulating fleece fabric, so your brow and ears will stay comfortably warm in cold conditions. Its high level of breathability means that it pulls moisture from your skin, further minimizing the effect of cold sweat after a hard effort. The Hincapie Sportswear Power Headband is available in one size in the colors Black, Red, and White.
