The Aero Race 3.1 Cycling Jersey is built for speed. This jersey started the Aero revolution in 2007 that has since been imitated by nearly every manufacturer and team. It has undergone continuous evolution since then. The 2012 Aero Race 3.1 Cycling Jersey has improved airflow in the area behind the shoulders and along the side panels using some innovative basic aerodynamic research and consulting with leading experts.

• The most aerodynamic racing jersey made by Castelli.
• Saves approximately 12 watts at 40KM/H compared to a normal race-fit jersey.
• Velocity fabric on front and shoulders with prosecco treatment to keep you dry.
    - Prosecco hydrophilic treatment speeds up evaporation by spreading moisture over a larger surface area within the fabric. The 3-D structure of the fabric holds the surface off the skin, improving wicking and reducing cling, keeping you dry and comfortable.
• Open mesh back and side panels for breathability.
• Silicone print at front sides to induce turbulence.
• Nervato fabric at arm holes for improved aerodynamics.
• 35CM YKK® camlock zipper.
• Silicone gripper elastic at waist.
• Giro3 arm elastic for flat, aero fit.
• Imported.
