Mizuno Altrax 81 is manufactured in Japan and is made from superior quality material, and this is the reason why the Racquet lasts for long. Also, this Racquet has a twisted aerodynamic profile because of its unique swirl geometry frame. The hexagon frame immensely increases the speed of the shot and offers great control and accuracy. The weight of the Racquet is 85gm which makes it feather-light, making it easy for the player. Also, if the Racquet is too heavy, then it becomes difficult for a player to use it for long and takes more force to play shots.
