Aero Race 8S Jersey - Men's

What Our Gearhead® Experts Are Saying:

“This jersey feels insanely fast. The ribbed shoulder fabric really works—you can feel how clean the air moves around you at speed. The body fabric is super breathable, the bonded sleeves are smooth, and the waist gripper keeps everything locked down even with full pockets. It’s my go-to for race days and fast group rides.”

We love the Castelli Aero Race 8S Jersey for how effortlessly it turns power into speed. Built using CFD-based fabric placement and seam shaping, it’s engineered for aerodynamic efficiency from the moment we roll out. The ribbed shoulder fabric is tuned specifically to reduce drag at race speeds, providing up to a 6% CdA gain compared to previous aero jerseys—a meaningful advantage when every watt counts.

While its aero gains steal the spotlight, the comfort is just as impressive. The lightweight, stretchy body fabric keeps airflow high and temperature low, and the bonded sleeve endings create a smooth, irritation-free fit. With supportive elastic around the waist and three stable rear pockets, it stays dialed whether we’re racing, riding hard, or chasing PRs.
