Highly reflective for enhanced visibility. Developed by 3M to help athletes be seen at nighttime and low light conditions. The 3M Scotchlight material provides increased visibility on the moving parts of the leg. This is extremely important because each year, many athletes are killed in traffic crashes. Of the total accidents, 65 percent of pedestrian fatalities occur between 6:00 p.m. and 6:00 a.m. Using Reflective clothing can increase visibility.
