Product Description

This jersey is a further development of the professional jersey from four years ago. Although Castelli now offers aerodynamically better jerseys, they have left this model in the collection. The Aero Race 4.0 was a very fast and at the same time comfortable all-round jersey that not only slim racers could handle well. For the 4.1 version a different direction was chosen. Away from racing and towards comfortable functions, which Castelli considered unnecessary when designing the 4.0. This updated jersey features an additional zippered pocket, an underlaid zipper strip at the top to protect the neck, redesigned ruffled velocity material at the front and an angled back pocket for easier access. These features make it the ideal jersey for all rides, whether you're sprinting for victory or well equipped for Sunday group rides.
