We packed our 0211s with three key GEN2 technologies. First and most important is a hollow body design filled with our proprietary COR2 polymer, the world's thinnest club face (made possible by the COR2) and a 360-degree undercut perimeter channel around the club face that expands the functional size of the face. These three technologies combined result in a club that goes farther, launches higher, feels softer, sounds great, is more forgiving and has a sweet spot the size of Texas.
