Difsea Thermal Cap

The original Difesa cap is a GORE-TEX INFINIUM™ WINDSTOPPER® piece that's best for extreme conditions. With the Difesa Thermal Castelli took away the windproofing, but by doing so dramatically improved the moisture management, so it's best for cool to cold conditions, especially with high-intensity riding. They placed a rib-knit wool wrap around the ears to keep you warm but keep it all relatively thin to fit under a helmet.
