Prologo 4 Full-Zip Jersey - Men's

Though it retains all of the Prologo 3's classically-inspired styling, Castelli's Prologo 4 Jersey represents a tick up on the tech scale. This bump, from three to four, comes courtesy of an improvement to the jersey's anti-moisture Stratus fabric. Stratus's 100% polyester inner layer pulls sweat away from the skin, transferring it to the thin, microfiber outer-layer. Once the moisture surfaces, Castelli's Prosecco treatment diffuses it over a larger surface area for thin concentration and rapid evaporation, all of which makes for a soft, breathable, and quick-drying jersey that feels light and airy on the skin.

The Prologo's simple (yet apparently elusive to many manufacturers) design is part technology and part tradition. The classic sponsor bar that the heroes of cycling's history wore across their chests is reimagined here in a more slender, laser-cut panel. The contrasting side panels and lower back are mesh for an additional touch of modern aesthetics and added breathability, which the full-length camlock zipper easily supplements in the high temperatures of summer.

Three standard rear pockets provide cargo space and a fourth, reflective zipper pocket all but guarantees you'll arrive home without losing your keys. Finally, the iconic red scorpion logo on the zipper pull deserves special mention, as it's indicative of the tiny details Castelli infuses in every jersey it makes.
