With REACTIV X System, you get explosive speed and increased distance on tee shots, while the ball stays on the club’s face longer during approach shots to give you more spin and a soft feel around the green. Tour B RXS is specially designed to deliver increased ball speed for maximum distance from the tee, while offering a soft feel and increased spin for superior control on approach shots. It’s ideal for players with swing speeds below 105 mph who are looking for extra spin.
