The Prologo 4 Full-Zip Jersey combines Castelli's classic designs with technical innovation to create a breathable, quick-drying jersey with a fit that will leave you inspired to ride. For the Prologo 4, Castelli used its new anti-moisture Stratus fabric, featuring a 100% polyester inner layer that pulls sweat from the skin and transfers it to the thin, microfiber outer layer. The Prosecco treatment disperses moisture once it surfaces, enhancing evaporation and keeping the jersey airy and light on your skin. To further improve breathability, the Prologo 4's side panels and lower back are mesh, and it has a full-length camlock zipper so you can dump heat on the fly. The Prologo also has three rear pockets, and a reflective zipper pocket, to ensure that your ride essentials are safe and secure.
