Isometric 

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.

Vibration Dampening Mesh

M40X

Power with a More Flexible Frame. A strong, elastic graphite is added in the throat to improve frame stability and flex.

Shockless Grommet System

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.

Aero Shape

Smoother contours throughout the racquet head for less wind resistance and extra racquet speed.

Isometric Expansion

An updated square-head frame that is wider at the 3 and 9 o’clock positions creates the largest sweet spot in EZONE history.
