The Perfetto RoS is the one jacket that does everything well. Castelli initially designed it as a cool-weather training and extreme weather race piece for the pro riders, but in reality, it excels in many conditions thanks to its full wind protection, great fit through stretchy fabrics, and best-in-class breathability. 

RoS in the name signifies Rain or Shine. The emphasis should be on dry weather comfort, which is where this jacket really excels, but then you get near waterproof protection if you do get caught in the rain. Castelli worked with Gore to develop two new exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabrics. They use a light fleece-lined water-resistant version on the forward-facing surfaces and a lighter, stretchier fabric on the back that maintains the breathability of the previous fabric while improving water repellency at the same time.
