Castelli Tutto Nano RoS Jersey

Warm, stretchy, water-repellent, and highly visible: the ideal mix for a spring and autumn jersey. Using the same material as our Nano Flex arm warmers, this premium jersey offers our best performance fit and 360° reflectivity. Perfect when paired with the Perfetto RoS 2 Vest.

Technical specifications:

• The Nano Flex 3G material features a warm, brushed fleece interior with 20% elastane for better stretch – along with Castelli's unmatched, water-repellent Nano Flex finish.
• Reflective inserts on the shoulders and under the back pockets.
• 3 back pockets.
• YKK® Vislon® zipper.
• Embossed logo.

Ready for a better jersey for the cool transitional period? The Tutto Nano RoS Jersey offers a range of upgrades compared to what you are likely wearing so far. First and foremost is the stretchy fit that perfectly accommodates your movements – made possible by the Nano Flex 3G material, which we also use in our arm and leg warmers as well as for our Sorpasso tights. This close fit actually makes the jersey warmer, as it doesn't flap in the wind.

Additionally, the material is knitted tighter compared to conventional thermal jersey fabrics. It allows less air to pass through, helping you stay warmer. Plus, there’s the water-repellent Nano technology finish developed by Castelli. On dry days, you won’t even notice it’s there, but when riding through light rain or over wet roads, you’ll stay drier.

The final feature is the 360° reflectivity, thanks to panels on the shoulders and lower back. And of course, there’s that signature Castelli attention to detail: see the extra smooth YKK® Vislon® zipper with a rubberized pull tab or the silicone waist gripper that prevents the jersey from riding up.
