Castelli Aero Race 5.1 Jersey

The Castelli Aero Race 5.1 short sleeved jersey is a lightweight, tight fitting, aerodynamic jersey for the real racers. No flapping fabrics or sleeves that are too wide. This jersey is aerodynamic to the core. They improved an already aerodynamic fabric so it’s even more aerodynamic. The Castelli Aero Race 5.1 is the jersey you want for those all-out exercises and some less eye-catching colours).
