Golf club head having a composite crown

A golf club head, comprising:

• a body having a sole, a front portion defining a front opening, a top portion defining an upper opening, and a side portion, the side portion extending rearward of the front portion and having toe, rear, and heel regions, a hosel extending outward from the top portion proximate the heel region, wherein the body is comprised of a metallic material having a density of at least about 4 g/cc, the upper opening located solely in the top portion of the body and comprising at least 25% of a total area of the top portion;
• a striking plate securely attached to the body portion and enclosing the front opening;
• a support member located solely in the top portion of the body and surrounding the upper opening;
• and
• a crown supported by and secured to the support member, thereby enclosing the upper opening, a first portion of the crown being sized to sit on the support member such that the first portion overlaps at least a portion of the support member, thereby forming a junction between the first portion of the crown and the body, the crown incorporating composite material having a 50% to 70% fiber volume ratio and a density between about 1.4 g/cc and 1.65 g/cc, and wherein the crown has a maximum thickness no greater than about 2 mm.

A golf club head comprising:

• a body having a sole, a front portion, a top portion defining an upper opening, and a side portion, the side portion extending rearward of the front portion and having toe, rear, and heel regions, a hosel extending outward from the top portion proximate the heel region, an upper edge being defined between the front portion and the top portion, the upper opening located solely in the top portion of the body and a support member located solely in the top portion of the body and surrounding the upper opening, wherein the body is comprised of a metallic material having a density of at least about 4 g/cc;
• a crown secured to the top portion and covering the upper opening and the support member, a first portion of the crown being sized to abut the support member such that the first portion overlaps the support member and is joined to the support member by adhesive thereby forming a junction between the first portion of the crown and the body, the crown incorporating composite material and having a density between 1 g/cc and 2 g/cc, the crown having a maximum thickness no greater than about 2 mm;
• and
• a shoulder extending adjacent to at least a frontward portion of the support member, the shoulder being a distance of at least 7 mm rearward from the upper edge;
• wherein the golf club head has a maximum coefficient of restitution of at least 0.80.
