The Pro Tour collection represents what Osaka stands for: high standards with superior appearance. The players should gain confidence and bring out the best in their game. The Pro Tour collection realizes that desire! This model is teardrop-shaped with high balance and is aimed at offensive players who want to get tremendous power in their smashes. The core of patented Snap® Foam is on the softer side and is designed to give the player extra opportunity to put spin on the ball, partly through a structure on the hitting surface called Quantum Spin® System and partly through the roughened surface.
