This short is the result of decades spent working to make long hours in the saddle even more comfortable. The material is the high-stretch Forza fabric. The 38% Lycra® content means that it is gently compressive whitel never binding. And it maintains an insanelxy soft hand. The nearly seamless construction is derived from the CASTELLI Body Paint shorts, which debuted a decade ago and started the trend of reduced seams while maintaining remarkable fit. Nothing to rub or break. The renowned Progetto X² Air Seamless seat pad gets an update in this season with a new skin care layer that features a remarkably soft new surface fabric and more stretch, which allows us to eliminate the front triangle.
