The original Difesa cap is a Windstopper® piece that''s best for extreme conditions. With the Difesa Thermal we take away the windproofing, but by doing so dramatically improve the moisture management, so it''s best for cool to cold conditions, especially with high-intensity riding. Castelli have placed a rib-knit wool wrap around the ears to keep you warm but keep it all relatively thin to fit under a helmet.
Key FeaturesThermoflex Core2 fabric on body of cap for warmth and optimal wicking to move moisture away from your skin
Wool-blend ear cover
Classic fit with vintage appeal
