A MARVEL OF ENGINEERING
Castelli's Aero Race Jersey 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. After introducing the Sanremo Speedsuit, we knew that a separate jersey and shorts would never be as aero for those days when absolute aerodynamics are a must. So we set out to engineer in better breathability and developed the new Velocity Dry fabric. We also changed to a full-length zipper for ease of use and worked on the fit and stretch so that the jersey now fits more people, not just GC contenders at the grand tours.The marvel is that we made it better wicking, better fitting and easier to use, but we maintained the aerodynamics of the previous Aero Race Jersey. Wind tunnel testing shows this jersey providing a 10- to 12-watt advantage over our already-aero Team jerseys at 40 km/h. That translates into about 35-40 seconds gained each hour.
