The first aero jersey project was named Split Second. In 2006, when Castelli designed the first aero jersey for road racing, people thought we were mad. Back then, aerodynamics were only for time - trials. Performance clothing focused on moisture management. You could even win the Tour de France with a baggy polyester T - shirt - like jersey. Our aerodynamic consultants expected only small gains, so we named it Split Second, but we believed even small improvements were worth it. In the end, the gains were significant, and we changed the look of the pro peloton. Each new generation is more aerodynamic and better - fitting. The Aero Race W Jersey uses CFD analysis of wake flow in the riding position to place fabrics and seams. It also incorporates feedback from pro riders, ensuring comfort during long - hour training and racing in all weather conditions.

To use this Castelli Women's Aero Pro Jersey, simply put it on before your bike ride. Make sure it fits well without being too tight or too loose. During your ride, the jersey's aero design will help you cut through the wind, and its moisture - management features will keep you dry. When it comes to maintenance, wash it in cold water with mild detergent. Don't use bleach or fabric softeners as they can damage the fabric. After washing, hang it to dry instead of using a dryer. Store it in a cool, dry place when not in use. This way, your jersey will last longer and keep performing at its best.
