Ready to upgrade to a better jersey for cool days? The Tutto Nano RoS jersey features a large number of improvements over the ones you currently use. First, the stretch fit allows the jersey to move with you, made possible by the Nano Flex 3G fabric, the same one we use to make our cuffs and leg grippers as well as our Sorpasso tights.
This close fit makes the jersey warmer, preventing the fabric from flapping in the wind.
Second, the tighter knit of the fabric compared to those used for traditional base layers lets less air through so you stay warmer.
Then there are the finishes with water-repellent nanotechnology, a Castelli hallmark. On dry days, you won't even notice it's there, but when you encounter light rain or wet roads, you'll stay drier.
Finally, 360° reflectivity, thanks to the panels on the shoulders and the lower back. And then, of course, there's Castelli's attention to detail, from the YKK® Vislon® self-lubricating zip with the rubberized pull tab to the non-slip gripper elastic to prevent the jersey from riding up.
