Low drag clubhead

A metal-wood type golf club head having improved aerodynamic properties, the golf club head having a club head frontmost point and a club head rearmost point, and the golf club head comprising:

• a striking face, the striking face defining the frontmost point;
• a sole connected to a bottom side of the striking face, the sole having a rearmost point;
• a crown connected to a topside of the striking face, the crown having a rearmost point;
• and
• a skirt,
• wherein:
• the sole has a closing ascent angle of less than about 35 degrees, the closing ascent angle being an angle between (1) a line from the rearmost point of the sole to a sole point, of a projected silhouette of the golf club head from a toe-side viewpoint and (2) a plane intersecting the sole point and parallel to a ground plane;
• or
• the crown has a closing descent angle of less than about 35 degrees, the closing descent angle being an angle between (1) a line from the rearmost point of the crown to a crown point, of the projected silhouette of the golf club head from the toe-side viewpoint, and (2) a plane intersecting the crown point and parallel to the ground plane,
• wherein the rearmost point on the sole is an intersection point of the sole and a lower boundary of the skirt, and the rearmost point on the crown is an intersection point of the crown and an upper boundary of the skirt, and
• wherein the lower boundary is a skirt height above the ground plane, and the skirt height satisfies a head-length-to-skirt-height ratio between 3:1 and 8:1.
