The TOUR B XS Tiger Woods Edition golf ball is a collaboration between Bridgestone Golf and Tiger Woods to allow golfers to play the exact ball Tiger uses in competition. From the unmistakable ‘TIGER’ side stamp to each ball having a number 1, this is the exact golf ball Tiger tees up. From a performance perspective, the TOUR B XS-TW edition balls are identical to the standard TOUR B XS model. The NEW TOUR B with REACTIV iQ is the SMARTER TOUR BALL. The proprietary NEW REACTIV iQ is a SMART cover technology that reacts to the force of impact. Off the tee, REACTIV iQ rebounds quickly delivering explosive velocity and increased distance. On approach shots, REACTIV iQ stays on the face longer, providing more spin and soft feel around the green. The TOUR B XS with REACTIV iQ delivers increased ball speed for MAXIMUM DISTANCE off the tee and a SOFT FEEL and INCREASED SPIN for CONTROL on approach shots.
