A/C 3 Cycling Cap boosts airflow with ultralight, fully ventilated mesh

What Our Gearhead® Experts Are Saying:


“This is my go-to cap for summer rides—it adds that classic cycling look without trapping heat. The mesh breathes incredibly well under the helmet, and because it’s so light, you forget you’re wearing it. Perfect for long climbs and hot days when you want shade without sweat buildup.”


We love the Castelli A/C 3 Cycling Cap for those scorching days when a little shade is welcome but overheating is not. Its fully ventilated mesh construction keeps air moving freely under the helmet, helping us stay cooler on long climbs and sunny stretches of road. The lightweight feel makes it a natural choice for summer riding, offering coverage without sacrificing breathability.


Designed in a one-size-fits-all structure, it slips easily under any helmet and provides that classic cycling silhouette while keeping things cool and comfortable on every ride.
