The lightest Phantom racquet to date, the Prince Phantom 100X (290g) tennis racquet provides great spin and feel for a wider range of players. Maintaining the low flex of other Phantom series tennis racquets, the Phantom 100X (290g) really delivers comfort and response. The beam width is designed with a Constant Taper System that provides more power than previous Phantom racquets. Anti Torque System (A.T.S.) combines TeXtreme and Twaron materials with Graphite to provide you with a very stable experience through impact, especially for a racquet that has a flex rating in the 50s.
