A high volume aerodynamic golf club head with a club head volume of at least 400 cc and a front-to-back dimension of at least 4.4 inches producing a face-on normalized aerodynamic drag force of less than 1.5 lbf when exposed to a 100 mph wind parallel to the ground plane and oriented at the front of the club head. The club head has a crown section having a crown apex located an apex height above a ground plane, wherein a portion of the crown section between the crown apex and the face has an apex-to-front radius of curvature that is less than 3 inches. The club head may have a post apex attachment promoting region on the surface of the crown section at an elevation above a maximum face height that begins at the crown apex and extends toward the back of the club head.
