Castelli Tutto Nano Ros W Jersey Jersey Black XS

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 we use to make our arm and leg warmers as well as our Sorpasso tights. 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 lets 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 360° 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.

WHAT IT IS

• Warm, stretchy, water-repellent and highly visible: the ideal mix for a spring and autumn jersey. Using the same fabric as our Nano Flex arm warmers, this premium jersey provides our best performance fit and 360° reflectivity. Ideal with the Perfetto RoS Vest.

NANO FLEX FABRIC

• Exclusively engineered by Castelli. We take our 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.
