A high volume aerodynamic golf club head having a post apex attachment promoting region 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 post apex attachment promoting region is on the surface of the crown section at an elevation above a maximum face height and begins at the crown apex and extends toward the back of the club head. The post apex attachment promoting region is a relatively flat portion of the crown section that is behind the crown apex, yet above the maximum top edge plane, and aides in keeping airflow attached to the club head once it flows past the crown apex.
