Bridgestone B330RX B Mark Golf Balls Switch to the B330-RX and feel what it is like to gain accuracy, distance, and a decisive advantage over the competition. The Tour B330-RX is specially crafted with AMATOURcore and SlipRes cover technology to increase your distance. The softer AMATOURcore generates more power for faster ball speed and the new patented SlipRes cover leverages spin for a longer, straighter shot. Features SlipRes Cover Our most durable cover creates more stability between your ball and your driver or wedge for increased distance and friction. AMATOUR Core Now bigger and better with our proprietary gradient technology causing a smoother energy transfer from inner to outer core for faster ball speed and reduced spin off the driver. Dual Dimple The inner dimple causes greater distance with more thrust power at launch and the outer dimple promotes a shallow angle of descent for increased roll. Seamless Cover Our golf balls do not have seams like the competition. The result is more consistency in accuracy, distance, and trajectory.
