Castelli Nano Flex Evo Arm Warmers - AW26

Nano Flex, a technology that has long been associated with Castelli, perfectly symbolizes their constant drive for product innovation. 

Over the years, the Nano Flex technology has seen different iterations, but never has it had such a major update as this latest version. With Castelli committed to removing all elements of PFAS from their product line, they engineered a new Nano Flex EVO technology. PFAS-free technologies require regular retreatment, but on a rainy day this product will protect you and keep you warm. With a polypropylene base fabric and Castelli’s nanotechnology treatment, Nano Flex is still the best clothing for bad weather. 

Features
