Warm, stretchy, and water-repellent. The tutto nano ros women’s jersey is the ideal mix for a spring and autumn jersey.Castelli make the tutto nano from the same nano flex 3g fabric it uses for its warmers and sorpasso tights. The high-stretch fabric creates a close-to-body fit that moves with you and does no flap, which in turn helps keep you warm.The fabric has castelli’s proprietary nanotechnology water-repellent treatments. On dry days you won’t notice it, but when the rain comes you will stay drier than in a normal thermal jersey and be able to get by for longer without having to reach for a jacket.When it comes to breathability, the tutto nano strikes a perfect midpoint between thermal jerseys and the water-repellent gore-tex jackets in castelli’s ros line-up. The tutto nano fabric is a tighter knit than the fabric used in thermal jerseys so it lets less air through keeping you warmer, but it is also more ventilating than gore-tex so you don’t overheat when the temperature does begin to rise.Castelli’s attention to detail extends throughout. There is 360 reflectivity thanks to panels on the shoulders and lower back, a ykk zipper with a rubberised pull, and an elastic silicone gripper at the waist holds jersey in place.
