Nano Flex EVO Arm Warmers

Castelli Nano Flex EVO Arm Warmers

Every cyclist knows the struggle of a damp, chilly transition season. The Castelli Nano Flex EVO Arm Warmers have been designed to make those transitional seasons easier to dress for.

Castelli has spent years perfecting their proprietary Nano Flex fabric technology, a breakthrough that perfectly symbolises a constant drive for product innovation. By coating thermal fabric with millions of ultra-tiny nanofilaments, Castelli has created an arm warmer that coaxes water to bead up and run right off the surface, without sacrificing the breathability you need when pushing up a steep climb. With the Castelli Nano Flex EVO Arm Warmers, you are not just buying extra coverage; you are investing in a high-performance, durable layer that extends your riding season.
