Castelli Women's Climbers A/C Cap

uilt for the hottest, hardest days in the saddle, the Castelli Women’s Climbers A/C Cap is designed to disappear under your helmet while keeping you cooler, drier and more comfortable. A super-lightweight, open-mesh upper maximizes airflow and sweat evaporation, while the soft anti-odour headband wicks moisture off your forehead to keep sweat from stinging your eyes during long climbs or indoor training.

With a women-specific fit that sits flatter and cleaner beneath modern helmets, this cap delivers functional coverage without bulk. Finished with clean Castelli graphics, it’s the summer essential you forget you’re wearing — until you take it off and realize how much it did.
