Additional Information




15L Gauge String, is a thick string with an "L" designation meaning that it is a half guage lighter than regulare 15 guage string. Since 15L string lies between the 15 and 16 gauges, it provides both control and durability.


Natural Gut Strings are made with part of the cow's intestine called the Serosa. Natural gut offers maximum feel and control due to low dynamic stiffness. This provides better ball "pocketing" and a slight texture surface for enhanced ball spin.


Multifilament Construction, are strings constructed with multiple fibers that are twisted together. This type of construction creates a string with more resiliency, feel and cushioning.


Thermogut is a process adopted by Babolat for gut strings, which employs high temperatures to enhance fiber cohesion throughout the entire string. This process improves the strings durability, resistance to humidity and retains the properties of gut.
