A good-looking, tour-level golf ball? You know you’d hit that.

The Bigga Balls U4 Prototype is built for high-speed players who demand maximum distance, control, and consistency. Designed for swing speeds over 105 mph+ and golfers with handicaps under 10+, this 4-piece tour ball delivers elite performance from tee to green.

At its core, the U4 features a dual rubber construction with a Coefficient of Restitution just below the USGA limit, creating an efficient rebound off the driver face for longer, more consistent drives without instability. An ionomer resin mantle transfers energy seamlessly from the core to the cover, boosting ball speed while reducing excess driver spin and maintaining controlled iron spin for optimal flight windows.

Finished with a soft urethane cover, the U4 grips the clubface like gorilla glue, generating tour-level spin and precision. The result is a smooth feel off wedges and putters, faster stopping power on the green, and confidence on every approach.
