A MARVEL OF ENGINEERING
The Castelli Aero Race 4.0 Full Zip Short Sleeve Cycling Jersey for men has completely revolutionized race clothing since its debut in 2007. Since then Castelli has continually improved it, but this 6th iteration represents perhaps the biggest step forward. Castelli set out to engineer in better breathability and developed the new Velocity Dry fabric, while also changing to a full-length zipper for ease of use and worked on the fit and stretch. The result is a marvel that contains better wicking, better fitting, easier use with the superb aerodynamics of its predecessors.
