Luxilon takes its pro tour bona fides and applies it to natural gut, the most responsive string material ever made. Composed of uniquely elastic serosa fibers, Luxilon Natural Gut offers phenomenal shock absorption while also remaining wonderfully crisp. The result is a string that protects your arm but still delivers the kind of direct feedback that makes you feel connected to the ball. In contrast to other natural guts, we were impressed by this stringR019s durability. The outstanding tension maintenance means that Luxilon Natural Gut remains playable longer than any synthetic on the market. Given this stringR019s feel, comfort and power, it will pair perfectly with your favorite co-poly. Players looking for maximum comfort, power and tension maintenance should give this string a serious look.
