Castelli Women's Perfetto ROS 2 Wind JerseyPowered by GORE-TEX INFINIUM™ WINDSTOPPER®, the Castelli Women's Perfetto ROS 2 Wind Jersey gives you the ideal combination of wind protection, water repellence and breathability. A cycling do-it-all for changeable weather.The Women's Perfetto ROS 2 Wind Jersey, previously known as the Perfetto Light, was made to meet the demands of pro riders. They wanted to wear a Gabba for racing but it proved a bit too hot when the intensity increased. And so, the Perfetto ROS 2 Wind Jersey offers reliable windproof and water-repellency but with the breathability required for comfort during for harder efforts. The versatile performance is derived from its combination of high-performance fabrics. For the front and sleeves, Castelli have used Gore-Tex INFINIUM™ WINDSTOPPER® 203 Stretch. This gives total wind protection as well as excellent water resistance. Meanwhile, the back is made with Nano Flex Light Woven, its nano-technology bringing you a high degree of breathability and protection from light rain and road spray. This versatile construction lets you wear it like a traditional gilet over a summer jersey, just with sleeves. Or pair it with a lightweight base layer and arm warmers and it’s a lightweight windproof cycling jersey on its own.Castelli have improved the front zipper – it’s now a smooth running two-way YKK® Vislon® zipper, allowing you to control ventilation from the top and bottom. The reflectivity is also now more visible, and the three rear pockets offer plenty of space for your essentials.Features:Materials: 100% PolyesterLightest Castelli short-sleeve wind protectionGORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch lightweight fabric on front and sleevesNano Flex Light Woven on back for breathable stretch with good water protectionTop- and bottom-opening YKK® Vislon® zipper for easy ventilation adjustment on the fly3 rear pocketsReflective panel at bottom of pocketsWeight: 164gSuggested Temperature range: 10 to 18 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
