Castelli Mens Prologo 4 Jersey

The Castelli Prologo 4 Jersey blends classic styling with modern performance, making it a versatile choice for training rides, long days in the saddle and warm-weather cycling. Designed with a close but not overly aggressive fit, it delivers the moisture management and ventilation expected from Castelli while remaining comfortable enough for everyday riding.

The jersey uses Stratus Plus two-layer fabric, engineered to move moisture away from the skin and promote faster evaporation. Mesh panels at the sides and lower back improve airflow and help the jersey conform naturally to the body. Finishing details include a laser-cut Castelli chest logo, full-length YKK zipper and three rear pockets, plus a separate zippered key pocket with reflective detailing.
