Castelli Women's Perfetto Air Vest Stay dry, warm, and perfectly comfortable with the Castelli Women's Perfetto Air Vest, an essential layering piece for cycling in cool and unpredictable conditions. Engineered with Castelli’s advanced Ristretto Technology, this mid-weight gilet offers just the right amount of insulation while restricting airflow enough to prevent internal moisture build-up. The result is a consistently dry and comfortable core, even during high-speed, high-effort rides. Developed in collaboration with textile innovators ITTTAI®, the Ristretto Lite fabric features PFAS-free DWR treatment, delivering exceptional breathability, stretch, and water resistance, all in one sleek, high-performance package. Designed for real-world road cycling demands, the Perfetto Air Vest includes a stretch-woven back for a snug, non-restrictive fit and excellent airflow. A top and bottom-opening YKK® Vislon® zip makes on-the-go ventilation simple, while three lie-flat rear pockets with internal security lips keep your ride essentials secure and accessible. Reflective piping at the bottom of the pockets enhances visibility in low-light conditions. Lightweight yet protective, this vest is perfect for layering over a jersey on chilly starts, fast descents, or variable spring and autumn rides.
