Golf club head

Abstract

A golf club head comprising a front portion, a rear portion, an upper portion and a lower portion arranged below the upper portion and vertically spaced therefrom. The upper portion of the golf club head comprises an upper port that is formed therethrough and is defined by a first inner edge 27, 127) thereof. The lower portion of the golf club head comprises a lower port, which is formed therethrough and is defined by a second inner edge thereof. Said upper and lower ports are arranged such that when an eye of a user of the golf club head is aligned therewith along a predetermined alignment axis, the second inner edge defining said lower port is fully visible to the user through said upper port.
