Now with more flexibility and weather protection, the Castelli Nano Flex+ Arm Warmers are made with the most water-repellent fabric finish ever. Nano Flex fabric combines thermal, fleecy stretch with millions of tiny nanofilaments that allow drops of water to stay as spherical balls on top of the fabric or bounce off the fabric without leaving a trace. Nano Flex Light fabric insert behind the elbow is highly elastic for better mobility. Double-sided silicone grippers stay put for a great fit in motion.
