What Our Gearhead(R) Experts Are Saying:"On sweltering summer rides, the A/C W Bibshort is my go-to. Its lightweight design and Progetto X2 Air chamois keep me cool and comfortable during long miles, while the minimalist bib straps make it feel like I'm barely wearing anything."When the road heats up, we turn to the A/C W Bibshort from Castelli to keep us cool and riding strong. Designed for high-output days, this bibshort combines a featherweight construction with closed-knit mesh side panels that maximize airflow while shielding us from the sun with UPF 50 protection. We love the Progetto X2 Air Seamless Donna chamois for its targeted cushioning, offering support without bulk for long hours in the saddle. Silicone grippers keep the bibshort in place so we can focus on our performance, while the minimalist bib straps feel airy and unobtrusive. From fast-paced training rides to endurance events, the A/C W Bibshort ensures we stay comfortable no matter how hot the summer gets.
