The first aero race jersey project was called split second and back in 2006, everyone thought Castelli was crazy. Back then, aero was only for TTs. Performance clothing meant moisture management. And you could win the Tour de France with a baggy jersey that was little more than a polyester T-shirt. Even Castelli's aerodynamic consultants expected limited gains, so they named the jersey Split Second, though, like now, they thought even small gains were worth pursuing. In the end, the gains were pretty substantial, and Castelli completely revolutionized the look of the pro peloton.
Castelli is now on the sixth major revision of there aero jersey. Each generation has become more aero and better fitting. The Aero Race W Jersey benefits heavily from CFD analysis of wake flow in the riding position for fabric and seam placement. It also benefits from pro riders' feedback, as they've worked to make the jersey comfortable for their long hours of training and then racing in every possible weather condition.
It's Castelli's most aero and most comfortable Aero Race Jersey yet. But they're already working on an update.
