Campagnolo Roubaix Arm warmers are designed to insulate your arm area while offering full range of motion. Silicone grippers ensure that the warmers do not slip or move while riding. Using flat seam stitching and an articulated design, you'll love how these warmers move with your arms.  Reflective Campagnolo logos enhance visibility. These are great as a base layer or wearing when temperatures are cool, and you need a little thermal protection. Soft inner fabric traps in your body heat so you stay warm. Sizing based on height. Sizing - Medium (Under 5'7"); Large (5'7"-5'10"); XL (Over 5'10")
