The Yonex Astrox 88S Tour is a performance badminton racket designed for hard-hitting players who play an aggressive, attack-oriented style. The racket offers superb consistency and accuracy with the isometric head which improves control without diminishing power. The Namd graphite used for the frame is responsible for storing energy during flex and releasing it in an explosive fashion on shuttle impact. The Astrox 88S Tour offers a great deal of manoeuvrability and speed thanks to the Aero Box frame construction, and shot smoothness is ensured with the Rotational Generator System. The racket is very nimble thanks to the Extra Slim shaft, which is also resistant to twisting thanks to the uniquely shaped Energy Boost Cap . The Astrox 88S Tour is pre-strung with the D637-A7 string.
