Slim enough to fit under your bike helmet for a barely-there feel, this unisex cap provides much-needed protection from the sun during long rides. The lightweight polyester fabric keeps sweat and light rain off your face so you can focus on the road or trail ahead. A shorter peak helps this cap stay in place when you start picking up speed. Whether you’re heading out for a casual weekend ride or gearing up for a race, the Up Cap is a must-have essential.
