Whether you typically wear an aero race-fit jersey or a regular cut jersey, the Espresso model will become your new favorite. First, we focused on the fit and fabric of this jersey. A material was developed that allows for a close-to-body fit without constricting or limiting freedom of movement. The fabric designed by Castelli also offers excellent breathability and moisture management, and performs exceptionally well in the wind tunnel. You can pack it full on the longest days without anything shifting. Your valuables can be securely stored in a fourth zippered pocket. Lastly, Castelli opted for a reliable, full-length YKK Vislon zipper. You will find yourself wearing this jersey time and again, no matter the ride, because Espresso is always a good idea.
