Castelli Nano Flex 3G Arm Warmers

The Castelli Nano Flex 3G arm warmers are an ideal solution for when you cycle in cold and/or wet conditions. As the Nano Flex 3G fabric has been further improved, these armpieces will keep you dry just a little longer than the previous models. And as the fabric retains its breathability, you can use them in dry conditions without perspiring excessively. Keep in mind that these arm warmers are not fully waterproof; in case of a heavy rain shower or a long ride in drizzly weather, you will eventually get wet.

The lining of these armpieces feels soft and warm, and the double-sided silicone grippers keep them in place during cycling. The single-seam flatlock stitches prevent the seam causing irritation, so that the arm warmers remain comfortable during long rides. Do you like to go for rides in cold and/or wet weather in your short-sleeve jersey with arm warmers? Then you should absolutely add the Castelli Nano Flex 3G armpieces to your wardrobe!
