Castelli Aero Race 8s Women's Jersey

Over a decade of expertise, innovation, and speed. Our fastest jersey is now even faster.

In the world of competitive cycling, we strive to get more watts and more speed out of our gear. Boosting speed through clothing is one of the best ways to get faster, since 80% of a cyclist’s drag is caused by the body. The Aero Race 8S W Jersey is the result of more than a decade of experience in optimising speed for professional cyclists, using cutting-edge methods and materials to develop the fastest jersey we’ve ever produced.

The S stands for “Speed.” CFD technology was used in the sleeve design to ensure optimal seam placement. The ribbed fabric on the shoulders was specifically developed to maximise aerodynamic benefits at race speed, reducing drag by 6% compared to previous aero jerseys. The rest of the jersey was designed for maximum comfort.

The fabric 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 fits perfectly and supports the three rear bags when they’re full. The Aero Race 8S W Jersey is the ultimate piece of gear to help you turn watts into speed.
