Nano Flex 3G KneeWarmer
For the flexibility to add and remove an extra layer on those chilly spring and fall rides, the Nano Flex 3G KneeWarmers are supremely versatile. Unlike wearing full-length tights or leg warmers, you're covered where it matters most. Your joints.
Proprietary to Castelli, the Nano Flex technology is a water-protective finish paired with their tried and true Thermoflex fabric, offering you the best coverage in all-conditions.
