Castelli Aero Race 8S Short Sleeve Jersey 2026

Over a decade of innovation and experience in the world of speed. Our fastest jersey today is even faster.

In the world of high-performance cycling, we want to get more watts and more speed from our gear. Clothing specifically designed for speed is the best way to go faster, because 80% of a cyclist’s aerodynamic drag comes from the body. Thanks to over a decade of innovation and experience in making professional riders faster, the Aero Race 8S Jersey was created with the most modern methods and fabrics and has become our fastest jersey ever. The S stands for “speed.” The sleeve construction is engineered and based on CFD for optimal seam placement. The engineered ribbed shoulder fabric is specially designed for maximum aerodynamic advantage at race speeds, with up to a 6% reduction in CdA compared to previous aerodynamic jerseys. The rest of the jersey is designed for maximum comfort. The smooth, stretchy main fabric allows for a perfect fit and optimal comfort on the skin. The elastic waistband keeps the jersey in place and supports the three rear pockets when loaded. The Aero Race 8S Jersey is the cutting-edge garment that turns your watts into speed.
