- ISOMETRIC™
Enlarged Sweet Spot
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.

- Namd
Revolutionary Graphite
A world-first, new dimension graphite material, Namd, greatly improves the adhesion of the graphite fibers and resin by attaching nanomaterial directly to the graphite fiber. In high-performance racquets, it is common to combine nanomaterials with resin that connects graphite fibers, but in Namd, nanomaterials have directly adhered to the graphite fibers, and resin is greatly increased. This major improvement produces a shaft that flexes and stores energy, delivering explosive force on impact with the shuttle.
- AERO+BOX Frame
Combines solid hitting feel and quick swing.
- 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.
- Energy Boost Cap PLUS
The uniquely shaped cap maximizes shaft performance. The front allows the shaft to flex, while the sides arch-shaped curve stabilizes the racquet face by preventing the shaft from twisting.
- Solid Feel Core
Cuts Vibration
The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid feel core is carried in all racquets manufactured in Japan.
- Extra Slim Shaft
Thinnest, Strongest Ever Produced by Yonex
Cutting edge NANOMETRIC carbon technology is used to produce an ultra-thin, ultra-tough, aerodynamic shaft, created for a stronger and more intense shot.
- Dual Optimum System
Power up your forehand and backhand with the Dual Optimum System.
- New Built-in T-Joint
The lightweight T-Joint increases stability of the shuttle on the strings, maximizing power and control.
- Power Assist Bumper
Attached to enforce heavier, increased power by configuring the weight directed into the shuttlecock with a tungsten-infused nylon bumper.
