Players now have access to the greatest spin in Yonex tennis history thanks to a combination of innovation, new technology, and structure that increases string snapback and movement. For novices and juniors making the move, a lightweight, agile racquet with a spin and speed design is ideal. A square-shaped ISOMETRIC racquet maximizes the intersection of the main and cross strings to produce a larger sweet spot than a traditional circular frame. More control is possible with ISOMETRIC technology without compromising power. For easier maneuverability and more spin, Aero Trench and Aero Fin Technologies lower air resistance.
