Castelli Tutto Nano ROS JerseyThe Castelli Tutto Nano ROS Jersey is cosily warm, just like a traditional thermal cycling jersey. But with its water-repellent nanotechnology finish, it brings with it a new level of all-weather protection come the cooler and damper months of the year. First thing you'll notice when you pull the Tutto Nano ROS (Rain or Shine) Jersey on is the snug stretch fit. This is thanks to the highly flexible Nano Flex 3G fabric, as found in Castelli's superb Sorpasso tights. This close fit not only saves precious energy but less flapping boosts warmth too. Speaking of warmth, the fleece inner is great at trapping body heat and the tight knit of the fabric lets less air through than traditional thermal jersey fabrics, enhancing warmth still further.Next comes Castelli’s proprietary nanotechnology water-repellent finish. When you're cycling in the dry you'll not notice it. However, on a damp and drizzly autumn day, it comes into its own, fending off light rain and wet roads, keeping you comfortable for longer. Spring and autumn days are shorter and so you'll also be pleased to find 360° reflectivity, keeping you visible as the night draws in. An easy-sliding KK® Vislon® zipper with rubberized pull and the silicone gripper elastic finish the jersey in style.If you're looking to upgrade your cool-weather cycling kit, the Tutto Nano ROS Jersey is a great place to start. Compared to a traditional thermal jersey it's a definite step up in performance.Features:Materials: 85% Polyamide, 15% ElastaneNano Flex 3G fabric - warm brushed fleece inside with 20% elastane for stretchNano Flex water-repellent finishReflective fabric inserts at the shoulder and on central pocket3 rear pocketsYKK® Vislon® zipperEmbossed logoSuggested temperature range: 12 to 17 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
