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. *Tested by Yonex New Grommet Pattern High-Performance The single-pass grommet hole construction provides more grommet holes for a more high-performance stringing pattern.
