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 RX with REACTIV iQ delivers increased ball speed for MAXIMUM DISTANCE off the tee and HIT & SIT performance on approach shots.
