Ideal for spring and fall, the Castelli TUTTO NANO ROS JERSEY is a warm, stretchy, breathable and highly visible men's zip-up jersey.

This top-of-the-line model offers the best possible fit thanks to its close fit that quickly flaps in the wind. Made of Nano Flex 3G stretch fabric with a warm brush fleece interior, it's tighter than traditional thermal jerseys and allows less air to pass through. In addition, it features Castelli's exclusive nanotechnological water repellent finish to keep you dry in light rain or on wet roads.

The jersey has 360° reflectivity, thanks to panels on the shoulders and lower back, and an easy-to-handle Vislon YKK zipper, not to mention the silicone tightening elastic that keeps the jersey from riding up.
