Aero Pro 8S Short-Sleeve Jersey - Men's

What Our Gearhead® Experts Are Saying:

"The Aero Race 8S Jersey excels in every aspect of speed and functionality. Its fabric placement is designed using CFD analysis to minimize drag, and the bonded sleeve edges ensure that nothing slows me down. It's ultra-light, fits like a second skin, and the reflective tabs are a great safety addition for dawn rides."

The Aero Race 8S Jersey is built for one purpose: speed. Castelli’s latest race jersey uses computational fluid dynamics (CFD) to engineer fabric placement and seam construction for an aerodynamic edge, cutting drag by as much as 6%. Bonded sleeve endings reduce turbulence and ensure a smooth interface between fabric and skin, enhancing airflow during sprints and long climbs.

The lightweight and breathable fabric offers optimal comfort in high-effort scenarios, helping us stay cool as we chase KOMs. Practical details like an elastic waistband, three rear pockets, and a full-length zipper for easy ventilation ensure the jersey performs flawlessly during the longest rides. Reflective elements add visibility for early morning training or post-sunset commutes, rounding out a pro-level jersey ready for any race or challenge.
