PEARL iZUMi Thermal Cycling Cap Black, One Size

Nothing beats the all-around protection of a winter cycling cap. Not only does this piece keep your head and ears warm, but the bill forms a seal over your glasses to shield your eyes from wind and rain. This cold-weather essential is built with thermal fabric that balances insulation with breathability. It fits comfortably under a helmet and a port in the rear allows ponytails to pass through.
