ISOMETRIC^TM technology continues to help the world’s greatest players achieve global success.

Developed over 30 years ago, the ISOMETRIC^TM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC^TM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.

ISOMETRIC^TM delivers greater control without sacrificing power. ISOMETRIC^TMis a Trademark of Yonex CO., LTD.

Solid Feel Core

Cuts Vibration

Reduces vibrations traveling down the shaft for improved comfort.

 

 

Sonic Flare System

Max Acceleration

Carefully selected high modulus graphite are strategically placed across the bottom of the frame to provide unrivalled power and stability for maximum shuttle acceleration.

 

 

 

Ultra PE Fiber

Lightweight fibers that withstand immense forces while absorbing unwanted shock and vibrations.

 

 

Super Slim Shaft

Reduced Air Resistance

Designed to slice through the air, generating speedy power.

 

 

Energy Boost CAP PLUS

Uniquely shaped cap which maximizes shaft performance. The front allows the shaft to flex, while the sides archshaped curve stabilizes the racquet face by preventing the shaft from twisting.

 

Super HMG

Super High modulus graphite

These ultra-elastic materials produce sharper power for all shots.

 

 

New Built-in T-Joint

The lightweight T-Joint increases stability of the shuttle on the strings, maximizing power and control.

 

AERO Frame

Cuts air resistance for faster swing speeds and increased maneuverability.
