80% of the drag on a cyclist comes from the body. Drawing on more than a decade of knowledge and innovation in making professional riders faster, the Aero Race 8S Jersey is the result of using the most modern methods and fabrics to create the fastest jersey Castelli has ever made.The sleeve construction uses CFD engineering for optimal seam placement. The engineered ribbed shoulder fabric has been designed specifically to provide the greatest aerodynamic advantage at race speeds, with a CdA savings of up to 6% over previous aero jerseys. The rest of the jersey is designed for maximum comfort. The body fabric is smooth and stretchy, allowing for a perfect fit, and it feels great against the skin. The elastic at the waist keeps the jersey in place while supporting the three back pockets when they are loaded.CFD-based fabric placement and seam constructionEngineered shoulder fabric used specifically to reduce drag at race speeds, with as much as 6% savings in CdABonded sleeve endings for comfortLightweight body fabric for optimal cooling, breathability, and comfortElastic waistband to keep jersey in place and support loaded pockets3 rear cargo pocketsReflective tab for added safety
