X-Fullerene: Positioned at the top of the frame, X-Fullerene bonds the carbon fibers in a revolutionary cross-linking pattern. Increased bonding strength within the material prevents the face twisting from a hard impact. X-Fullerene also makes it possible to create a thinner frame to reduce air resistance but retain quick maneuverability.

Isometric: The Isometric Square Head Shape reduces the inert space found in a conventional round frame. As a result, the racquet is easier to swing through and has superior maneuverability with a 10% bigger sweetspot than an ordinary round head racquet. The sweetspot is the area of a racquet where the longest main and longest cross strings meet in the stringbed. In an ordinary round frame racquet, the sweetspot is where the 8 main and 11 cross strings meet. In the Yonex Isometric Square Head racquet, 10 main and 13 cross strings meet in the stringbed to produce a sweetspot that is 10% larger than the effective hitting area of a conventional round head racquet. With more strings of equal length and a larger effective hitting area in the stringbed, the Isometric Square Head Shape provides consistently accurate shots, giving more power, control and more effective off-center hits.

IPS: Integrated Power Weight System positions extra weight at the sides of the frame to give the face a greater moment of inertia.

Oval Pressed Shaft: OPS technology builds into the throat, the right amount of flex for an extended dwell time for easier spin and directional control.
