AERO+BOX Frame - Combines solid hitting feel and quick swing.
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.
Rotational Generator System - Counterbalanced Weight Distribution - By applying the counterbalance theory, weight is distributed throughout the grip end, frame top and the joint for maximum control. The transition to the next shot can be performed smoothly, with rapid succession.
