Castelli Aero Race 8S Short Sleeve Jersey CS250100104

Castelli Aero Race 8S Short Sleeve Jersey More efficiency. More speed. The Castelli Aero Race 8S Short Sleeve Jersey is focused on saving you precious watts. When the decisive moments of a race kick off you can be confident you're not wasting power at the pointy end of proceedings. With 80% of drag coming from the body, the 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 - savings that could be the difference between making the race-winning break or leading your race rivals in the sprint.  When making harder efforts, be it in training or racing, 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 cycling jersey just got faster.
