Castelli use Gore® Windstopper® X-Lite Plus on the front and shoulders of the Women's Perfetto Vest, giving reliable weather protection, keeping out wind and shrugging off showers. This is combined with Nano Flex Light on the back that also gives water repellency but is primarily used to provide a high level of breathability and enabling Castelli to achieve an extremely aero fit. While it's not as packable as their lighter vests, the Perfetto achieves a greater level of weather protection so is ideally suited to cooler and damper conditions.
The neck is cut high to seal out cold breezes and a full-length zipper, complete with rear storm flap, makes controlling ventilation quick and easy. Lastly, the addition of reflective trim on the back adds extra visibility when light levels drop. If the weather does warm up it's compact enough to fit into a jersey pocket.
Whether worn as an outer layer on cool days, keeping off a chill on a descent or added as a mid-layer on cold days the Women's Perfetto Vest offers impressive versatility for all your riding needs.
