The RB566 is an even softer feeling version of its predecessor with a new micro-dimple configuration to maintain hang-time past the apex of flight. With a softer yet higher energy core, the RB566 offers a great balance of high trajectory, soft feel and all-round performance. Suitable for mid to low swing speeds.

NEW HIGH ENERGY, SOFT FEEL CORE

Creates a satisfying balance of ball speed and softer feel.

MICRO / D-DIMPLE DESIGN FOR ADDED HANG TIME

At mid/low ball speeds, the lift effect of both Micro and D-Dimples become effective at extending overall flight.

IONOMER COVER

For a blend of greenside feel and all-year-round durability.

“With a softer ball like the RB566, feel is a priority and aerodynamics become the key to maintaining distance. We’ve found that at lower swing speeds, the higher, straighter flight of the RB566 and impact of the smaller dimples outweigh any minor loss of ball speed (of a harder ball).”
