Castelli Women's Perfetto Air Jacket Stay warmer, drier, and more comfortable for longer with the Castelli Women's Perfetto Air Jacket, the ultimate solution for tackling cool and changeable cycling conditions. Developed in partnership with fabric innovator ITTTAI®, this jacket features Castelli's exclusive Ristretto Technology, which restricts excess airflow while maintaining outstanding breathability. The result? You stay dry from the inside out, avoiding that dreaded clammy feeling during intense efforts. With Ristretto Lite fabric and a PFAS-free DWR treatment, the Perfetto Air Jacket offers advanced water resistance and thermal regulation, a perfect balance of protection and performance. Every detail of the Women's Perfetto Air Jacket is designed with the rider in mind. The engineered waist and raw-cut lie-flat back keep cold air out without adding bulk, while the top- and bottom-opening YKK® Vislon® zip ensures easy ventilation control on the move. Three lie-flat rear pockets with a security lip keep your essentials secure, and reflective elements on the back boost visibility in low-light conditions. Whether you're heading out for tempo intervals or a long winter base ride, this is the must-have jacket for serious cyclists who refuse to compromise on comfort or performance.
