Castelli delivers an incredible range of innovative and excellent protection grade options, and the Rain or Shine (RoS) line-up cam keep you well equipped. The Perfetto RoS 2 Vest can almost seem like an anachronism, but this is a true Perfetto product, dominated by GORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch lightweight fabric on front panels onto the shoulders. This wonderfully light, incredibly effective fabric provides lightweight wind and water protection. On the back side Castelli has added their own Nanoflex Light Woven textile for breathable stretch with good water protection for great protection from wheel spray and sudden downpours. Optimal for periodically wet or dry conditions from the 57°-68°F, the Perfetto RoS vest is one of the best true true protection vests we have tested.

From the modified Gabba collar, to the full exterior zipper wind flap, the finish details are top notch. Fit is close and fitted, with arm holes that close on you to prevent in-flow and and stop any billowing in its tracks. The Gabba theme carries on with the longer dropped tail with a reflective panel. Though the vest weighs just 222 grams in a size large (with impressive front and rear protection), it is highly packable- half pocket style. The Perfetto Vest itself has an exterior rear dual pocket system with a pump sleeve that makes your life easier when the conditions dictate that it needs to stay on for a while. Of course Castelli gives you a smooth running, reliable YKK Vislon zipper and reflective highlights as well. This is the vest that you carry on those questionable days in early summer, or anytime you head into the big hills and mountains that have their own ideas about climate that rarely conform to the calendar, or a meteorologist.
