Castelli Women's Perfetto 2 Vest At the heart of the Women's Perfetto 2 Vest is Castelli?s innovative Ristretto Lite fabric technology, developed in partnership with fabric specialists ITTTAI®. This exclusive construction combines advanced stretch, weather protection and outstanding breathability through cutting-edge membrane and lamination expertise. The result is a vest that keeps you warm, dry and comfortable when temperatures drop. Meanwhile, the PFAS-free DWR treatment helps repel light rain and road spray without compromising environmental considerations. A stretch-woven rear panel further enhances ventilation and freedom of movement, ensuring unrestricted comfort on every ride. Practical details make the Perfetto 2 gilet as functional as it is protective. The top- and bottom-opening YKK® Vislon® zip allows easy temperature regulation and quick access to jersey pockets, while three lie-flat rear pockets with an internal security lip provide secure storage for ride essentials. Whether you're heading out for a brisk morning training session, tackling long autumn miles or adding an extra layer for changeable conditions, the Castelli Perfetto 2 Vest delivers the warmth, versatility and premium performance serious cyclists demand.
