Castelli A/C Bibshort 2025

For the hottest days in the saddle

Summers are getting hotter and hotter and those who have to train during the hottest hours of the day, for example during the lunch break, need kit that is as cool as possible. The new A/C Bibshort has been developed to allow maximum cooling and breathability, as well as offering sun protection. The design of the shorts is designed to keep you cool. The side and leg grips are made of closed mesh to maximise air circulation and lower the temperature. Although minimised, the braces keep the shorts in place. The Progetto X2 Air Seamless pad is comfortable all day and dries quickly. Everything in the A/C Bibshorts is designed with one goal: comfort and coolness on the hottest days.
