Who It’s For: Golfers who want more distance off the tee and tour-level greenside spin.

The Skinny: Bridgestone has modified the casing layer of the Tour B balls to help them generate more speed while complementing the unique urethane cover that provides more spin around the greens.

The Deep Dive: For golfers who may not be aware, Bridgestone has been making solid-core, urethane-covered golf balls as long as any brand in the industry, and the Nike golf ball that Tiger Woods used to win four consecutive majors (the Tiger Slam) was manufactured by Bridgestone. Nick Price won the British Open and PGA Championships using a Bridgestone ball, Nick Faldo won at Augusta National with a Bridgestone, and, more recently, Tiger won the 2019 Masters, and Bryson DeChambeau won at Winged Foot in 2020 using a Bridgestone ball.

Since 2020, the Japanese brand has focused on contact science, studying how different combinations of materials can enhance speed and distance off the tee while also providing more greenside spin and control for different types of players. The addition of impact modifiers to create the Reactiv cover of the 2020 Tour B X, Tour B XS, Tour B RX and Tour B RXS four years ago was the first fruit of that labor, followed by the ReactivIQ covers that were uniquely created for each ball in the 2022 Toru B lineup. Now, for 2024, Bridgestone is claiming it has taken another step toward creating the Holy Grail of golf balls by developing the new ReactivX system.

The ReactivX system is comprised of two parts: an Xclrnt mid-layer (pronounced accelerant) and a ReactivIQ urethane cover.

Instead of using multiple cores inside each of the four Tour B balls, Bridgestone has designed a gradational core that is very soft in the center and gradually gets firmer toward the perimeter. A firm mid-layer (mantle) is then applied over the core, but in the 2024 Tour B balls, that casing layer does a better job of transferring energy into ball speed.

The new Xclrnt mid-layer is also more dense, so golfers like Tiger and Jason Day, who started testing and using the ball in 2023, reported it has a lower, deeper sound at impact.
