Product Overview

The SiDi Katia short is a versatile option for regular riders who want reliable performance without a race‑day feel. The combination of compressive fabric, women's specific padding and stay‑put leg grippers helps maintain comfort across varied riding styles, from turbo sessions and fitness classes to weekend road rides and commuting.[web:2][web:4][web:7]

With a close, body‑hugging cut typical of Castelli women's shorts, the Katia is designed to follow your riding position, support key muscle groups and minimise excess fabric that can flap or bunch. The result is a neat, streamlined short that feels supportive rather than restrictive once you are on the bike.[web:2][web:4][web:6]
