The MTB PRIME X is a ball with fast initial speed, low spin and distance. Perfect performance from tee shots to putting The next generation of 3 piece urethane golf balls just like MTB PRIME. The performance of a long shot is the same as PRIME, with high initial and low spin but its designed for a clicky feel. The FLEX mantle provides mild spin on irons. Optimized aerodynamics to reduce spin and achieve high ballistic Core: The newly developed ultra-high rebound core achieves initial speed up and low spin speed between the driver and FW. Mantle: The newly developed FLEX mantle works with the core to allow spin control of iron shots while reducing driver spin amount. Dimpling: The newly developed dimple construction prevents wind from being affected by the wind even in high ballistic roads. Urethane Cover: The durable urethane cover is not only has a flexible spin rate. Comfort emphasis ■ USGA/R&A certified ball
