OPS (O.P.S. System)
This unique feature is designed to give you more spin, control and feel for the ball. The narrow shaft flexes on impact, minimizing shock to the arm and increasing dwell time, or the amount of time the ball is in contact with the string bed.
Quad Power System
By combining the new Quad Power System with Yonex's unique Isometric head design, EZONE provides an exceptionally stable frame and enlarged sweetspot - creating an 'Explosive Zone' in the stringbed that enhances your natural power.
