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™ technology delivers greater control without sacrificing power.
