Abstract

A golf club head having a high moment of inertia is disclosed herein. The golf club head preferably has a volume ranging from 450 cubic centimeters to 475 cubic centimeters, a mass ranging from 180 grams to 225 grams, and a length ranging from 4.0 inches to 5.0 inches. The golf club head preferably has a moment of inertia, Iyy, about the center of gravity of the golf club head ranging from 2000 grams-centimeters squared to 4000 grams-centimeters squared. Preferably, a middle section of the golf club head has less than 20% of the mass of the golf club head.

Claims

1. A golf club head comprising:

a body having a front wall, a crown wall, a sole wall, a heel wall, a rear wall, and a toe wall, the body defining a hollow interior;

wherein the golf club head has a volume ranging from 450 cubic centimeters to 475 cubic centimeters;

wherein the golf club head has a mass ranging from 180 grams to 225 grams;

wherein the golf club head has a length as measured from the forwardmost extent of the front wall to a rearward most extent of the rear wall ranging from 4.0 inches to 5.0 inches;

wherein the golf club head has a moment of inertia, Iyy, about the center of gravity of the golf club head greater than 4000 grams-centimeters squared and a moment of inertia, Izz, about the center of gravity of the golf club head greater than 5000 grams-centimeters squared.
