Uncompromising power, control and comfort

A new type of Monofilament string.

After 4 years of Research & Development, we have developed a new type of Monofilament string:

This string meets the objectives of power, control and comfort, without compromise. Our goal was to find a type of string that better fits modern tennis, the morphology and the age of the players. Made in France, our unique DUAL DYNAMICS® range has been developed on tennis courts, as close as possible to players. This proximity, the exchanges with the players, listening to their feelings and their performance requirements has allowed us to develop these unique strings.


Before our arrival, it was up to the player to adapt to his monofilament string. Today, with DUAL DYNAMICS® the string adapts to the different playing styles of the player.
