Castelli Nano Flex 3G Armwarmer

Nano Flex for All Occasions

Nano Flex Warmers are distinguished by their extremely versatile range of applications. They provide warming comfort like classic warmers while also offering decent moisture protection in the rain. As the first manufacturer, we have used water-repellent thermal materials for cycling apparel. Many have attempted 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.
