Product Description
More flex, more nano: Our Nano Flex warmers have been in Castelli's collection for seven years, and they've finally found a way to improve them. Castelli have added an insert on the back in Nano Light fabric to help them bend around your elbow or knee better while keeping all the water protection. More comfort due to more flexibility, and in a slightly more compact package.
