Castelli Nano Flex 3G

Nano Flex Warmers are distinguished by their extremely versatile range of applications. They provide warmth like classic warmers but primarily offer decent moisture protection in the rain. As the first manufacturer, they have used water-repellent thermal materials for cycling clothing. Many have tried to imitate Castelli's Nano Flex – always without success. Uncompromising in all conditions. Water-repellent, warming, and breathable Nano Flex material. A flat seam. Silicone grippers inside and out for a secure fit.
