Castelli Tutto Nano RoS jersey

Warm, stretchy, water-repellent and highly visible: the ideal mix for a spring and autumn jersey

Ready to move up to a better cool-weather jersey? The Tutto Nano RoS Jersey features a number of upgrades compared to what you've probably been using.
First is the stretch fit that moves perfectly with you, made possible by the Nano Flex 3G fabric, the same fabric Castelli use to make the arm and leg warmers. This close-to-body fit actually makes the jersey warmer by avoiding fabric flapping in the wind.
Second is the tighter knit of the fabric compared to traditional thermal jersey fabrics. It less air through so you stay warmer. Next is Castelli's proprietary nanotechnology water-repellent finish. On dry days you won't even know it's there, but when you get some light rain or wet roads then you stay drier.
Last is the 360º reflectivity, thanks to the panels on the shoulders and lower back.
Of course, the Castelli attention to detail is there, with the easy-sliding YKK Vislon zipper with rubberized pull and the silicone gripper elastic to prevent the jersey from riding up.

Technology

Nano Flex

Exclusively engineered by Castelli. They took their thermal fleecy stretch Thermoflex fabric and coat it with millions of tiny nanofilaments to create the most water-repellent fabric finish ever. Drops of water stay as spherical balls on top of the fabric or bounce off the fabric without leaving a trace.
