Castelli Nano Flex 3G Kneewarmer

The Castelli Nano Flex 3G Knee Warmer blocks early morning chill to keep your knees warm so you have no restrictions of movement. The water-repellant treatment keeps you dry by causing road spray to roll off your legs. In addition to protection from cold, wet weather, studies have proven the Nano Flex 3G Knee Warmer will block 99.8% of damaging UV rays. The seamless construction provides a silky-soft surface and double-sided silicone elastic has been added at the top and bottom to keep the knee warmers comfortably in place. When the temperature rises as the sun comes up, fold them up into a small package and store them in a back-jersey pocket.
