TheYONEXPolytour Air 125 Tennis Strings are the perfect strings for people with a softer, more controlled on-court style. With 200 meters of sky blue string, you will be set for a while! These stylish, light blue, 1.25 millimeter strings provide a level of give that is not found in many sets of strings. Part of the reason that this innovation is possible is the incorporation of HR-Elastomer, a soft polyester that allows the tennis string to bend and return to its original shape. It not only allows for more control, is helps increase shock absorption as well.
