The Castelli Superleggera bib short is the ideal cycling shorts to use during the hottest days of summer. The fabric used by Castelli is the Gradient Stretch Woven material which is extremely lightweight but still gives enough support to the muscles during cycling. The braces are also made from extremely thin mesh to keep the trousers as light and breathable as possible. This makes them suitable for use in temperatures of up to 40 degrees. Saving weight is a key factor, as the Castelli Superleggera is up to 50% lighter than regular short trousers. Even the Castelli logo has been thought of to keep the trousers as airy as possible. The logo is not put on the trousers as is often done, but is embossed in the trouser leg so that it stretches well and contributes to the breathability of the trousers. The grippers at the trouser legs are integrated and ensure that the trousers stay nicely in place. To complete the cycling shorts without compromising on comfort, this Castelli Superleggera bibshort is equipped with the Castelli Progetto X2 Air chamois.
