Golf club head
View Patent ↗The invention provides a wood-type golf club head comprising a body, a striking plate, and crown. The body has a sole, a front defining a front opening, a top portion defining an upper opening, an upper edge disposed between and separating the front opening and the upper opening, and a side portion. The side portion extends rearward of the front opening and has toe, rear and heel regions. The body is comprised of a metallic material having a density of at least about 4 g/cc. The striking plate is attached to the body, enclosing the front opening. The crown is attached to the body and encloses the upper opening. The crown is comprised of a non-metallic material. The golf club head has a maximum coefficient of restitution of at least 0.80 and a volume of at least 150 cc.
