There is no such thing as a race day outfit that is too comfortable. Even if you race more against your personal best than sponsored pros, the Castelli Free Aero Race 4 Bib Shorts offer a lot for you. The Progetto X2 Air Seamless seat pad uses a soft and stretchy layer against your skin in tandem with a supple cushion for endless support on epic rides. Ample mesh and stretch fabrics keep you well-ventilated and moving with ease until you reach the checkered flag, and flatlock stitching prevents chafing. Go for gold.
