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.
A new frame shape "ISOMETRICTM Expansion" that is wider at the 3 and 9 o’clock positions creates the largest sweet spot in EZONE history
A stretchy mesh material "VDM" is wrapped around the graphite within the grip to filter unwanted vibrations.
By varying the outer angle of the aero-shaped frame, the middle and upper hoop are plush, while the lower hoop is stable.
Shockless Grommets are integrated at the side and bottom of the frame to minimize muscle fatigue and provide a soft feel at impact to protect the wrist, forearm, and elbow by absorbing shock.
Shaft corners are rounded for an ideal flex at impact to increase dwell time for optimal spin and directional control.
Straight hole grommets elongate the strings to optimize power and comfort on off-center shots.
The cushioning performance of the grip helps minimize vibrations to protect the wrist, forearm, and elbow against shock-induced injuries.
