Abstract
A golf club (40) having a club head (42) with a frame member (60) and a body (61) is disclosed herein. The front member (60) has a front portion (72) and a return portion (74). The body (61) has a crown portion (62), a sole portion (64), a front wall (87) and optionally a ribbon section (90). A transition from the front wall to the crown portion (62) has a radius of curvature of at least 0.250 inch. The softer radius of the transition allows for a more durable and better performing club head. The frame member (60) may also be weighted to move the center of gravity of the club head forward toward the front wall (87).
