The Castelli Perfetto RoS 2 Rosso Corsa jacket, equipped with the exclusive GORE-TEX INFINIUM™ windproof fabric, is a windproof garment for cold days on the road. This garment excels in dry conditions thanks to its high breathability, as well as in wet conditions thanks to Castelli's exclusive GORE-TEX INFINIUM™ WINDSTOPPER fabrics. There is a lightweight, water-resistant fleece-lined fabric on the front and a lighter, stretch fabric on the back that maximises breathability while providing excellent water repellency. The Perfetto RoS 2 jacket keeps out all the cold wind without compromising breathability. It features a YKK Vislon zip with top and bottom vents for adjustable ventilation. The reflectivity on the back ensures greater visibility. The seam at the top of the shoulder has been moved to the back compared to previous versions, and the three pockets have a large capacity.
