Castelli Head Thingy 2015

Wear the light, breathable Castelli Summer Cycling Cap under a cycling helmet and the plastic inner visor shades your face and eyes from the menacing sun. This is the perfect summer cycling cap because the front panel is made of a polyester microfiber mix that wicks moisture and keeps your head dry. At the back, the air flows through the highly breathable poly mesh so your head stays cool. One size fits all.
