Ultralight, hyper breathable helmets are designed to let the air in and keep you ventilated, not to keep you warm. Castelli's Difesa is there to give you the best of both worlds and play defense when necessary. Windstopper X-Lite front and side panels will keep the wind from getting through to your head. Knowing, however, that some ventilation is necessary, Castelli used their breathable NanoFlex fabric on the rear panel and flip-down earflaps to allow all the hot air to escape away from your head. A traditional visor is in place to keep wind, rain, sleet, hail, dirt, and cameras out of your face. So when it comes time to get down to the nitty gritty aspect of training this winter, let Castelli's Difesa Cap be there to help you through.
