The first string engineered to process swing speed and adapt its properties in real time, Luxilon Smart Tennis String does all the thinking for you. Fiber characteristics within the polymer material change based on swing speed, stiffening up during fast swings for more control and flexing during slower swings for enhanced touch. Uniquely developed for lower string tensions, LXN Smart delivers polyester-like performance with the soft feeling of a multifilament. No matter the stroke or situation, this string gives you the ability to vary your shot selection with incredible confidence.
