Castelli Aero Race 8S Jersey

More than a decade of speed innovation and knowledge. Our fastest jersey is now faster.

In the world of performance cycling, we seek out more watts and more speed from our equipment. Dressing for speed is one of the best ways to get faster, since 80% of the drag on a cyclist comes from the body. Drawing on more than a decade of innovation and knowledge in making professional riders faster, the Aero Race 8S Jersey is the result of using the most modern methods and fabrics to create the fastest jersey we've ever made. The S stands for "speed." The sleeve construction uses CFD engineering for optimal seam placement. The engineered ribbed shoulder fabric has been designed specifically for the greatest aerodynamic advantage at race speeds, with a CdA savings of up to 6% over previous aero jerseys. The rest of the jersey is designed for maximum comfort. The body fabric is smooth and stretchy, allowing for a perfect fit, and it feels great against the skin. The elastic at the waist keeps the jersey in place while supporting the three back pockets when they are loaded. The Aero Race 8S Jersey is the ultimate piece of equipment to help you turn your watts into speed.
