Described herein are embodiments of an iron-type golf club head comprising a rear opening and an insert. The insert either partially or fully occupies the club head interior cavity. The insert damps vibrations occurring within the club head at impact to provide a desirable sound and feel. The insert is formed of a low-density material, thereby providing a significant damping effect while also creating discretionary mass.

Embodiments of mallet-style putter-type golf club heads comprising a first color and an alignment system to draw a golfer's eye towards a particular desirable location are described herein. The alignment system includes a central line extending rearward from a top edge centerpoint toward the rear portion and comprising a second color different from the first color. The alignment system further includes a focus element having a first grouping of lines and a second grouping of lines each extending rearward parallel to the central line and comprising a base abutting a top edge. Each of the first grouping of lines and the second grouping of lines further comprise at least the second color, a color saturation that changes as the lines extend rearward from the top edge, and line lengths that decrease as the first grouping of lines and the second grouping of lines are distributed further from the central line. The alignment system's changes in color, color saturation, and line length provide means to draw the human eye into focus at a particular desirable location to minimize mis-strokes that would cause undesirable variance from the desired trajectory or roll path.
