This jersey is the latest incarnation of Castelli's iconic pro racing jersey series. It's also their first aero race jersey that didn't get retired when the next generation of faster, sleeker jerseys came along. The Aero Race 4.0 Jersey was very fast, but also featured an amazing mix of classic design and a stretchy fit that works on a wide range of body types, not just the skinny racer. For the 4.1 version, Castelli took it in a different direction, away from pro racing, by giving it the convenience features that seamed superfluous when they dreamed up the 4.0 to win the Giro d'Italia. This updated jersey gets a zippered rear pocket, a flap behind the zipper to protect your neck, updated Velocity dimpled fabric on the front and an angled pocket for easier access. It all comes together to make one ideal jersey for all your rides, whether you're sprinting for the win or trying to survive the Sunday group ride.
Velocity dimpled fabric for improved wicking and faster drying
Full-length YKK zipper features integrated neck protector
Meticulously engineered to save 12 watts at 40 km/h compared to standard racing jerseys
