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

What Our Gearhead® Experts Are Saying:

“This jersey is all about speed. The CFD-based fabric placement minimizes drag, and the engineered shoulder panels cut through the wind, giving me an edge when racing or training at high intensity. It’s ultra-lightweight and breathable, keeping me cool on long, hot rides. The bonded sleeve endings feel sleek and comfortable, while the YKK® Vislon® zipper makes mid-ride adjustments easy. If you’re serious about performance, this jersey is a game-changer.”

For us, speed isn’t just about pushing watts—it’s about efficiency, precision, and the perfect fit. The Aero Race 8S Jersey has been fine-tuned through years of wind tunnel testing and pro peloton feedback, resulting in Castelli’s fastest jersey yet. Designed with CFD-based fabric placement and engineered shoulder panels, it reduces drag and optimizes aerodynamics, helping us cut through the wind with ease.

But it’s not just fast—it’s also built for comfort. The ultra-lightweight fabric keeps us cool when the race heats up, while bonded sleeve endings offer a sleek, second-skin feel. The YKK® Vislon® zipper provides smooth on-the-go ventilation, and reflective tabs add visibility for early-morning training rides. When every second counts, we trust this jersey to help us ride at our absolute best.
