*The main body is made of 6AL-4V titanium casting, and the hitting surface is inset with C-type DAT 55G ultra-high COR material
*The oversized (466CC) design has a 20 percent increase in the area of the hitting surface compared to the traditional driver, with a wider hitting area and higher  tolerance rate
*The thickness around the hitting surface is only 2.1mm, and the center point is 2.5mm. The gradual thickness design enables the 345D to easily reach the CT value of 300, and achieve the target of ultra-long distance
*The sole is coated with abrasion resistant nano coating for higher durability
