Tutto Nano Ros Jersey - Men's | Castelli

Ready to upgrade to a brand-new cool-weather jersey? The Tutto Nano RoS jersey offers several technical improvements over what you're probably familiar with. First, its stretch cut hugs your body perfectly, following your every move, thanks to Nano Flex 3G fabric – the same fabric we use in our arm and leg warmers, as well as our Sorpasso tights. Its close-fitting design provides extra warmth and prevents the fabric from flapping in the wind. Second, its weave is tighter than that of traditional thermal jersey fabrics, meaning less airflow for added warmth. You also now benefit from Castelli's exclusive water-repellent finish, achieved through nanotechnology. In dry conditions, you'll forget you're even wearing it, but in light rain or on wet roads, you'll stay perfectly dry. Finally, it offers 360° reflectivity, thanks to its reflective panels on the shoulders and lower back. Our attention to detail, such as the easy-to-use YKK® Vislon® zip with rubberized slider and the silicone elastic band that prevents the jersey from riding up, is proof of this.
