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. An apex ratio of the apex height to a maximum face top edge height is at least 1.13. The apex height and location of the crown apex obtain desirable airflow reattachment close to the face and improve airflow attachment to the crown section.
