DUAL OPTIMUM SYSTEM
Two contrasting racquet profiles in one unique Dual Dynamic Design allow players to enhance both their forehand and backhand.

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.
