CASTELLI Summer Skullcap, White, One Size;

When helmet padding just won't cut it to keep the sweat out of your eyes on mid-summer rides, don the Castelli Summer Skullcap to keep cool and dry. Made to sit unobtrusively under your helmet, this cap is constructed of a wicking layer around the headband to sop up sweat and keep your eyes sting-free. Across the top, a mesh layer provides oodles of ventilation and protects your dome from harmful sun rays for cool, worry-free miles.
