1. A wood-type golf club head comprising:
- a body having a face wall, a crown wall, a sole wall, a heel wall, a rear wall, and a toe wall, the heel wall extending 2.0 inches to 5.0 inches rearward from a perimeter of the face wall, the rear wall substantially perpendicular to the heel wall and extending from 2.5 inches to 5.5 inches from an aft edge of the heel wall, and the toe wall substantially perpendicular to the rear wall and the toe wall extending from 2.0 inches to 5.0 inches from an aft edge of the toe wall toward the perimeter of the face wall, wherein the crown, the sole, the face wall, the heel wall, the rear wall and the toe wall define a hollow interior;
wherein the golf club head has a volume ranging from 420 cubic centimeters to 480 cubic centimeters and a mass ranging from 190 grams to 250 grams;
wherein a moment of inertia about the Izz axis through the center of gravity of the golf club head is greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head is greater than 2000 grams-centimeters squared; and
wherein more than 50% of the volume of the golf club head is forward of the center of gravity of the golf club head and less than 50% of the mass of the golf club head is forward of the center of gravity, wherein forward of the center of gravity is toward the face wall.
