Abstract
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.
