Golf club head

A golf club head that, when oriented in a reference position, comprises:

• a loft no less than 40 degrees;
• a striking face having a face center, a leading edge, and a virtual striking face plane generally parallel to the striking face, the striking face defining a front surface of the golf club head;
• a rear surface opposite the front surface, the rear surface including a rear surface periphery;
• a hosel;
• a toe portion;
• a heel portion opposite the toe portion;
• a sole portion, including:
• an upper sole surface;
• a bottom sole surface;
• and
• a recess extending in a heel-to-toe direction along the upper sole surface and having a depth that varies in the heel-to-toe direction such that a first depth corresponds with a first location heelward of the face center and a second depth corresponds with a second location toe-ward of the face center, the first depth being between 10 mm and 20 mm and greater than the second depth by between 5 mm and 20 mm;
• a top portion;
• a perimeter weighting element comprising a thickened portion spanning about the periphery of the rear surface;
• a virtual vertical center plane, perpendicular to the virtual striking face plane and passing through the face center;
• and
• a center of gravity of the golf club head spaced no greater than 5.0 mm from the virtual vertical center plane.
