The Perfetto RoS 2 Wind Rosso Corsa short sleeve jersey, equipped with the exclusive GORE-TEX INFINIUM windproof fabric, is designed as a lighter and more breathable version of the Gabba for autumn. Its construction achieves the constant feeling of thermal protection of a jacket, but offers almost the same lightness and freedom of movement as a summer jersey. It is designed to be worn differently depending on the weather conditions, functioning as an outer layer on mild days or being complemented by sleeves in cooler temperatures. Includes quality details such as a YKK Vislon zip with top and bottom vents for adjustable ventilation. The reflectivity on the back is more visible for optimal visibility on the road.
