Bridgestone Tour B RXS Golf Balls. Softer Feel With Maximum Greenside Spin. Bridgestone have reinvented the Tour B RXS to feature new REACTIV iQ cover technology. Until now you had to choose more distance or more spin. With REACTIV iQ you can now get more distance and more spin out of the same golf ball. Designed to fit golfers with swing speeds under 105mph, the new Tour B RXS has softer feel and maximum greenside spin, allowing you to stop approach and pitch shots on a dime. Consistent flight and performance in the Tour B balls are a result of the proprietary Seamless Cover Technology. Validated professionally by Fred Couples.
