Castelli Tutto Nano RoS Jersey

Ready to upgrade to a better jersey for cool days?
The Tutto Nano RoS Jersey offers a significant number of improvements over what you’re currently using.
First of all, the stretchy fit allows the jersey to move with you, made possible by the Nano Flex 3G fabric — the same material we use for our arm and leg warmers, as well as the Sorpasso tights. This close-to-body fit keeps you warmer by preventing fabric from flapping in the wind.

Secondly, the tighter weave of the fabric, compared to that of traditional thermal jerseys, lets through less air, helping you retain more warmth.
Then there’s the water-repellent nanotechnology finishing — a signature feature from Castelli. On dry days, you won’t even notice it, but when you face light rain or wet roads, it’ll keep you drier.
Finally, there’s 360° reflectivity, thanks to reflective panels on the shoulders and lower back.
And of course, there's Castelli’s attention to detail — from the smooth-sliding YKK® Vislon® zipper with a rubber puller, to the gripper elastic that keeps the jersey in place.

• Nano Flex 3G fabric features a warm brushed fleece interior with 20% elastane for stretch, and Castelli’s unmatched Nano Flex water-repellent treatment
• Reflective fabric inserts on shoulders and center rear pocket
• 3 rear pockets
• YKK® Vislon® zipper
