ISOMETRIC™ technology continues to help the world´s greatest players achieve global success.

Developed over 30 years ago, the ISOMETRIC™ design increases the sweet spot by 7%*.

Compared to a conventional round frame, a square-shaped ISOMETRIC™ racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.

ISOMETRIC™ delivers greater control without sacrificing power.

ISOMETRIC™ is a Trademark of Yonex CO., LTD.

- Unity of String & Frame:

Muscle Power locates the string on rounded archways that eliminate stress-load and fatigue through contact friction.

This construction creates total unity of the string and frame through closer and tighter contact.
