If we had to choose one jacket for fall and winter riding, the extremely versatile Castelli Perfetto RoS 2 Jacket is our top pick. Built with GORE-TEX INFINIUM WINDSTOPPER fabric, this jersey offers superior wind and water protection without sacrificing breathability. With no insulation, we are able to easily add a thermal layer for freezing cold conditions or stick with a thin base layer for cooler days. Color: red
