CHOOSE THE RIGHT SEAT PAD
The seat pad is one of the most important differences between Castelli bibshorts.

Progetto X² Air Seamless is Castelli’s premium seat pad and is used across models such as Premio Evo, Free Aero Race S, Espresso 2, A/C, Endurance 4, and Unlimited Endurance. It is designed around long-distance comfort and airflow.
KISS AIR 2
KISS Air 2 provides comfortable cushioning without excessive bulk and is used in bibshorts including Competizione 2, Entrata 2, and Unlimited 2 Cargo.
FIND YOUR SIZE
The right fit is essential for comfort and performance. Cycling bibshorts should fit close to the body without restricting movement, with the seat pad held securely in position while riding.
Use a flexible measuring tape and compare your measurements with the Castelli size chart. If your measurements fall between two sizes, choose the larger size for a more comfortable fit.
