Soudal/Quick-Step Aero Race 8S Jersey - Men's

What Our Gearhead® Experts Are Saying:

"This jersey is built for speed. The combination of CFD-based fabric placement and engineered shoulder panels makes a noticeable difference in reducing drag at race pace. It’s one of the lightest, most breathable jerseys I’ve worn, keeping me cool even on hot days. The bonded sleeve endings add comfort, and the YKK® Vislon® zipper lets me adjust airflow easily. Whether I’m sprinting for the line or pushing the pace on a training ride, this jersey helps me perform at my best."

The Aero Race 8S Jersey is the result of more than a decade of aerodynamic innovation, blending cutting-edge materials with wind-tunnel-tested design. Castelli’s CFD-based fabric placement and engineered shoulder panels work together to minimize aerodynamic drag, reducing resistance by as much as 6% at race speeds. This means every watt we put down translates to maximum efficiency on the road.

Beyond aerodynamics, the jersey delivers elite-level comfort. The ultra-lightweight body fabric optimizes cooling and moisture management, making it ideal for warm-weather races and high-intensity training. Bonded sleeve endings eliminate excess bulk, creating a seamless, second-skin fit that enhances aerodynamics without sacrificing comfort. The YKK® Vislon® zipper ensures effortless ventilation control, while reflective tabs provide added safety when the sun starts to set.

With three rear cargo pockets, we can carry everything we need without disrupting performance. Whether hammering through a time trial or setting up a sprint finish, the Aero Race 8S Jersey is built for cyclists who demand the absolute best.
