The Castelli Perfetto RoS Convertible Jacket gives you unbeatable dry-weather comfort whilst keeping you protected when the rain picks up. A versatile garment with superb wind and rain protection, it can be worn as a long sleeve jacket or a short sleeve Gabba. Bringing the widely lauded Perfetto into the Rain or Shine (RoS) family, this new convertible jacket is a remarkable feat of garment innovation. Worrying about potential weather conditions before setting out on a ride will be a thing of the past, simply layer up according to the temperatures expected and enjoy your winter training. Each arm is zipped just above the elbows giving you the opportunity to own two garments in one. The zippers aren’t visible or felt when worn owing to a sleek design. On cooler days you’ve got a Perfetto RoS Long Sleeve Jacket and more moderate days a Gabba. The Gore-Tex Infinium fabrics utilised in the Perfetto RoS Long Sleeve are the result of a dedicated collaboration between Castelli’s R & D team and Gore offering unrivalled, high-grade water protection, keeping you dry when the heavens open. The body-mapped dual fabric construction is ideally suited to winter training. The warm brushed fabric on the front offers optimal water resistance just where it’s needed on exposed areas, and the lightweight stretch fabric on the rear gives much needed ventilation, whilst maintaining water repellent properties.
