The Prince Vortex 100 (300g) features a 14x21 string pattern that delivers plenty of spin potential and power. The 21 cross strings pattern helps harness the spin and power of this racquet. Prince's Anti-Torque System (ATS) combines TeXtreme and Twaron technologies and is strategically placed in the hoop and shaft for improved torsional stability.
