ISOMETRIC
Enlarged Sweet Spot
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.
