The Free Aero Race 4 Bibshort is our top race short, which also means that it's insanely comfortable even if you never pin on a number.
Engineered for aerodynamics and WorldTour racing performance. The careful choice of fabrics and components and the obsessive attention to detail make this bibshort supremely comfortable even when you don't pin on a number.
The Perfetto Vest has been a favorite with everyone from our pro riders to Castelli staff to performance cyclists everywhere. But we wanted to make it even more perfect, so we developed a new exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabric that is both lighter and more water repellent than the old fabric while maintaining the stretch and breathability.DISCOVER MORE
