Isometric
Isometric is Yonexs unique form theory that enlarges the sweet area.
The vertical and horizontal string length is equally closed, allowing for a larger sweet area up and down to left/right than typical circular frames. It has a larger sweet area than a typical round racket.
Energy Boost Cap
The shaft is flexible and has a shape that reduces twisting and transfers energy accumulated by bending to the shuttle without loss. It also reduces surface shake and increases control.
Slim Shaft
Slimmed shaft reduces air resistance and increases maneuverability.
Nano Mesh Neo
The frame is strong and supple and the shaft is flexible for a large amount of power.
Built-in T-Joint
Built-in T-type joint makes it highly resistant to twisting and increases surface stability.
