ISOMETRIC
Enlarged Sweet Spot
ISOMETRICTM technology continues to help the world’s greatest players achieve global success.
Developed over 30 years ago, the ISOMETRICTM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRICTM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.
ISOMETRICTM delivers greater control without sacrificing power. ISOMETRICTM is a Trademark of Yonex CO., LTD.
