Carlton Kinesis 4.1 badminton racquets are made out of Japanese hi-module carbon 40T and Japanese carbon. These racquets are durable and resistant. The G3 grip size provides a soft, yet solid hold on the racquets, hence adding to the medium stiffness and even headedness to make them apt for both offensive and defensive gameplays. The head shape is isometric with extended sweet spot which enables you to hit more powerful shots. These racquets are meant for experienced badminton players and can be used for both practice as well as regular matches. These racquets are basically unstrung, making it easier for you to customize the string tension according to your needs.
