RB566 is developed for players looking for a soft ball with stable performance throughout the game. The updated core provides better energy transfer at impact, while keeping the feel comfortable on all types of shots. Aerodynamics have been improved using a combination of micro- and D-shaped dimples that extend the ball’s hang time, especially at lower swing and ball speeds. The higher and straighter trajectory means that the RB566 performs reliably even with slower swings. The ionomer cover gives a durable surface and adequate spin around the green, making the ball a good choice all year round.
