Performance Perfected. That's the Perfetto.
The Perfetto ROS Light is their lightest windproof jersey but it's not just about keeping the wind out, the jersey is also exceptionally breathable and for this season gets a boost to rain protection too.
Using Castelli exclusive GORE-TEX INFINIUM™ 203 Stretch lightweight fabric to the front and sleeves you'll find you have greater levels of protection in light rain and showers, letting you concentrate on powering the pedals should the clouds burst open. However, even in poor weather, cycling will soon build up heat and with it comes sweat too, a real mood killer if not dealt with quickly. To keep cold and clammy sweat from spoiling your ride the back of the jersey is made with Castelli's Nano Flex Light Woven fabric. It's a highly breathable material that allows vapour to escape before causing you discomfort. Nano Flex Light is also more water-repellent than its predecessor adding to the versatility of this brilliant Perfetto ROS Light.
Details also count hugely towards on the bike comfort and here the YKK® Vislon® zipper is easy to use when you need extra ventilation, a Gabba style dropped tail, with a large reflective panel, keeps wheel spray off and boosts visibility as daylight fades to black and with two larger rear pockets, accessing essentials is easier than ever, even with gloves on.
Improved in nearly every way, the Perfetto ROS Light jersey is lighter, more water repellent and gets improved breathability making it an essential for your spring and autumn training and racing.
