Castelli Women's Aero Pro 8S Jersey
The Castelli Women's Aero Race 8S Jersey is designed to save you hard-won watts. When the decisive moments of a race are decided, you can be confident you're not wasting efforts to overcome unnecessary drag. With 80% of drag coming from the body, the Women's Aero Race 8S is engineered to be as slippery through the air as possible. Computational fluid dynamics (CFD) has allowed Castelli to place the sleeve seams precisely to reduce drag as speeds increase. The shoulder fabric also contributes to drag reduction, with Castelli claiming a 6% savings in CdA at race speeds - watt savings that could be the difference between making the race-winning break and winning the race to the finish line.
When working hard, the lightweight and stretchy body fabric gives a body-hugging and comfortable fit while optimising moisture management. Three rear pockets keep your nutrition within easy reach and an elastic waist provides pocket support and a smooth finish. With a decade of knowledge and innovation distilled, Castelli's fastest women's cycling jersey just got faster.

If you're unfamiliar with your Castelli size, we recommend you go up one size to obtain the best fit possible. Note that you do not need to size up for jackets or vests; please select your normal jersey size.
Castelli clothing is designed for its intended use and should be comfortable when on your bike in a riding position. Your garment should be snug to provide you with moisture-wicking capabilities, as an aerodynamic aid and prevent any fabric from flapping in the wind.
If you require any advice on Castelli sizing, please do not hesitate to contact us.

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
