TaylorMade M4

The company has always found useful ways to seamlessly blend technologies into a single iron set. This iron continues that heritage in a refined shape that pleases at address. The face and sole slots are most visible, but just as important are internal beams that stiffen the body of the club to assist sound and maximize face flex. The topline undercut—where wasted mass is often trapped—has been thinned to 1.2 millimeters, allowing saved weight to be used to lower the center of gravity for ease in getting shots airborne.
