Castelli Nano Flex 3 Socks

Castelli Nano Flex Socks are the perfect choice for cyclists tackling any challenge during transitional autumn or winter seasons. They take their name from the construction material—Nano Flex—whose primary job is complete protection against moisture, wind, and cold. The fiber weave technique combines thousands of nano particles that form a fabric impenetrable to water and wind while delivering impressive thermal regulation properties. The upper part of the socks is finished with silicone grip, which ensures they stay in place.
