The PROFORMANCE Arm Warmers Light are perfect for cool mornings when you know that the weather will be nice later. The warmers are made of recycled materials and they feel very comfortable on the skin. The arm warmers are very elastic and easy to put on and take off. As soon as the temperature rises, you can easily store them because they are thin and lightweight. The arm warmers have a silicone gripper to hold them in place, no matter how fast you ride.
