Well, it’s now a whole lot easier to choose what to wear with the Perfetto ROS Light Jersey, the lightest and most breathable Perfetto but still with exceptional wind and water resistance. Exclusive GORE-TEX INFINIUM™ 203 Stretch lightweight fabric is used to the front and sleeves and this fends off chilly winds, persistent drizzle and sudden showers leaving you comfortable as you face into the weather. Meanwhile, the back of the Perfetto ROS Light is made with Castelli’s extremely breathable Nano Flex Light Woven fabric and this ensures that the sweat you generate doesn’t hang around to cause discomfort and prevents cold clamminess building as you put the power down.
