Sorry, these clubs are currently sold out. Please check back soon for other golf club specials. One magazine has called the 3DX Hybrid Iron the "longest 5 iron in the world." The idea is to make an efficient, integrated hybrid iron set that would get rid of the large gap between the 4-hybrid and the 5-iron. The result is a ball flight that matches your current long iron, but that soars 20-25 yards further.
