The Castelli Perfetto Light Jersey is ideally suited to cool temperatures, especially when it’s dry or there’s a risk of light rain, and its highly breathable design won’t overheat, no matter how hard you ride. Gore Windstopper 150 fabric on the front, sleeves and yoke provides lightweight wind protection and repels water. Nano Light fabric on the back also sheds water and allows the body to breathe. A full-length YKK Vislon zipper makes it easy to further regulate core temperature and is easy to open and close. The drop tail hem offers protection from the elements while a silicone gripper waistband ensures the jersey stays perfectly placed. Reflective trim enhances visibility in low light or fog and three back pockets are perfect for carrying nutrition, spare tubes, and other essentials.
