After 99 prototypes and the most exhaustive testing, we've put a Mizuno ball through, we created the perfect duo for our next generation of tour players. Both the RB Tour and RB Tour X feel sensationally soft at impact, as you would expect from Mizuno. Both lower spinning and efficient from the driver. With an AXIALFLOW dimple that creates a high launch from the driver (compared to other tour-type balls) and a flatter flight from the short irons (compared to other tour-type balls).

"The ultimate difference with the new RB Tour has been the time spent working on the prototypes - 3 years of player, robot and greenside feedback across every possible performance attribute. Via parallel R&D teams - our original ball group in Japan, backed up by our unit in Atlanta US."

David Llewellyn - Director of R&D / Mizuno USA

Our most exhaustively tested balls ever: Mizuno set 2 R&D teams the task of working in parallel for over three years to identify the ideal balance of construction, compression, dimple configuration and cover.

AXIALFLOW dimple: On full shots, the new dimple generates a higher driver flight and flatter wedge flight, when compared to other tour-level balls.

Sensationally soft feel is not everything: A soft feel is always expected from Mizuno - but the new RB Tour cover was tested for over three years to ensure its durability is equally satisfying.

Just 272 dimples for a more defined look: A larger, more defined dimple creates a more precise outline and visual effect preferred by the majority of our testers.

Choose RB Tour X for low driver spin and RB Tour for even lower: Golf balls engineered for a new generation of faster clubhead speed players.

"We purposefully slanted the performance of both RB Tour models towards our younger elite players. Both models launch high off the driver - one with low spin, the other lower. Yet both balls demonstrated a flatter flight from full wedge shots. A remarkable accomplishment from the aerodynamics team in Japan."
