Yonex 4XP Isometric

13% wider sweet spot,5% faster ball speed, New "4XP ISOMETRIC"

Yonex's new "4XP(4 extra power)ISOMETRIC" construction has been developed for a wider sweet spot. By indenting the 4 corners of the frame, a greater number of main and cross strings are equalized to enlarge the sweet spot by 13% (compared to the conventional round head racquets) for more consistent shot accuracy.
