YONEX ASTROX 99PRO CHERRY SUNBURST 4UG5

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 are 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.

Power up your forehand and backhand with the Dual Optimum System.

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.

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.

The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid feel core is carried in all racquets manufactured in Japan.
