Castelli Aero Race 8S Jersey

More than ten years of know-how, innovation, and speed. Our fastest jersey is now even faster.

In the world of competitive cycling, we strive to extract more watts and speed from our equipment. Enhancing speed through clothing is one of the best ways to become faster, as 80% of a cyclist's air resistance is attributed to the body. The Aero Race 8S Jersey is the result of over a decade of experience in speed optimization for professional cyclists, utilizing cutting-edge methods and materials to develop the fastest jersey we have ever produced. The "S" stands for "Speed." CFD technology was used in the sleeve design for optimal seam placement. The ribbed material on the shoulder area was specifically developed to provide the greatest aerodynamic advantages at racing speeds, reducing air resistance by 6% compared to previous Aero jerseys. The rest of the jersey is designed for maximum comfort. The material on the upper body is pleasantly smooth and stretchy, ensuring a perfect fit and feeling great against the skin. The elastic waistband ensures the jersey stays in place and supports the three rear pockets when they are full. The Aero Race 8S Jersey is the ultimate piece of your gear that helps you convert watts into speed.
