We engineered this ball to be long. Really long. The only thing better than how far it goes is how good value they are. This 2 piece construction features a high-compression core with a DuPont Surlyn cover that's long lasting and resilient. Fair warning - this is not a ball for slow swing speeds. This is for those who crush it, and have the clubhead speed to really compress the ball at impact. The optimized 392 dimple icosahedron pattern provides optimum lift and stability for a long, straight ball flight. Combined, this leads to a long ball with lower spin rates for straight, long drives that will leave your playing mates in awe!Compression – 90Conforms to USGA regulations
