What Our Gearhead® Experts Are Saying:
"I can’t believe how effective the A/C Bibshort is at keeping me cool in peak summer heat. The mesh construction doesn’t sacrifice support, and the seamless chamois feels great even on century rides. It’s the perfect companion for warm-weather training."
Hot summer rides call for exceptional gear, and the Castelli A/C Bibshort is our answer to rising temperatures. Engineered with closed-knit mesh panels, this bibshort delivers remarkable airflow, keeping us cool and dry even when the road feels like an oven. The Progetto X2 Air Seamless chamois combines dual-layer cushioning and a skin-care layer for a plush, chafe-free fit, letting us ride longer with complete comfort.
The tailored fit and lightweight build enhance aerodynamics without restricting movement, while the silicone leg grippers ensure everything stays securely in place through every mile. Designed for temperatures ranging from 71 to 104°F, this bibshort lets us perform at our best, whether climbing steep gradients or flying along flat stretches. Ride confidently under the sun with UPF 50+ protection built right in.
