The Castelli Aero Race 6. 0 Jersey was designed to perform in the Pro Peloton all day, offering incredible comfort, moisture management and aerodynamic savings. Designed utilising computational fluid dynamics in collaboration with Castelli's Pro-Peloton Riders, the Aero Race 6. 0 Jersey offers a snug, tailored fit optimised for efficiency between 30 and 55km/h. While it doesn't skimp on comfort either, with the use of 3D Mesh Fabric to ensure you remain cool and dry whether you're training or dropping the hammer on the final sprint and 3 pockets so you can carry plenty of snacks to keep you going! The Castelli Aero Race 6. 0 Jersey has been designed to lead the breakaway and won't let you settle for second best, ever!
