A great revolution for the big jumping series. Overwhelming performance that everyone can get. Yet, it achieves a sharp "face" that covers the common sense of a jumping series. No more bouncing and good faces. Introducing inpres DRIVESTAR Sharp face for overwhelming flight and high ballistic 3POINT RESONANCETECHNOLOGY aggregates the "gradient" at the "striking point" and "center of gravity". Maximum Efficiency On a regular iron, the "gradient center" is often separated from the face of the face to the striking point and center of gravity. Therefore, the ribs can be placed effectively and closer to the shape of the figure, achieved maximum efficiency of flying. Adopting the new X37 material, the ultra-thin sole is 0.04 inch (1.1 mm) for maximum rebound performance. Adopts the new X37 material with high strength and tenacity strength and a more precise design. This makes the sole extremely thin at only 1.1 mm. Increased sagging at impact and further improved rebound performance. Ultra Low Center of Gravity Design: Large capacity of 1.6 oz (46 g) tungsten for extra flight and high ballistic The cavity part is equipped with 1.6 oz (46 g) tungsten (#7I) to achieve a low center of gravity with a height of 0.75 inches (19.0 mm). The ideal iron ballistic to capture the green. Good Face: We thoroughly pursue the shape of an iron. New inpress irons that dont compromise distance performance and shape.
