Made to be the perfect vest. GORE-TEX INFINIUM™ WINDSTOPPER® wind and water protection on the front, and a breathable nanotechnology water-repellent back. Stretch fit, and packable into half a pocket when not needed. This is a core piece of your cycling wardrobe.

The Perfetto RoS 2 Vest is our attempt at the perfect vest. It's warm and windproof yet breathable thanks to the Castelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabric on the front and the membrane-free Nano Flex stretch woven back fabric. It's splash resistant for wet roads or changing conditions. It's light and packable, easily fitting in a jersey pocket with room to spare. It has three rear pockets of its own and a two-way YKK® Vislon® zipper you can open it from the bottom to access gear in your jersey pockets. It has 360° reflectivity thanks to the reflective trim on the armholes and reflective band below the pockets. It fits close to body with a high collar that feels oh-so-comfy for cooler conditions.
