Castelli Nano Flex 3G Arwarmer

The Castelli Nano Flex 3G Arm Warmer blocks early morning chill as well as causes water droplets to roll off so you stay dry. In addition to protection from cold, wet weather, the Nano Flex Arm Warmer will block 99.8% of damaging UV rays. Besides armoring against the elements, Castelli upped the comfort level by creating a seamless construction that provides very smooth surfaces. Soft material and smooth surfaces feel great against skin. Double-sided silicone elastic has been added at both ends to keep arm warmers comfortably in place. When no longer needed in the middle of a ride, you can fold them into a small package so they take up limited space in a single back-jersey pocket.
