Abstract

A cavity back golf club head having a bridge member is disclosed. The bridge member extends across a first rear cavity connecting a heel and a toe of the golf club head to control the trajectory of a golf ball. For the longer iron clubs, a wall extending from the sole portion of the cavity back golf club head to the bridge member defines a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the wall extends from the top portion of the cavity back golf club head to the bridge member
