Golf club head

A golf club head, comprising:

• a body defining an interior cavity, a sole portion positioned at a bottom portion of the golf club head, a crown portion positioned at a top portion of the golf club head, and a skirt portion positioned around a periphery of the golf club head between the sole and the crown, the body also having a forward portion and a rearward portion and a maximum above ground height;
• and
• a face positioned at the forward portion of the body;
• at least one weight attached to the sole of the golf club head;
• a slot positioned in the sole of the club head and extending into an interior cavity of the club head, the slot extending substantially in a heel-to-toe direction;
• wherein:
• the body height is less than about 46 mm;
• and
• the face has a loft angle greater than about 13 degrees;
• and
• wherein the golf club head has a center of gravity (CG) located at an above ground center-of-gravity location (Zup) that is less than about 19.0 mm, a center-of-gravity z-axis extends vertically through the CG, and a center-of-gravity x-axis extends horizontally through the CG in a direction generally tangential to the face at the ideal impact location;
• wherein the golf club head has a CG with a head origin x-axis (CGx) coordinate, a head origin y-axis (CGy) coordinate, and a head origin z-axis (CGz) coordinate;
• further wherein the golf club head:
• has a moment of inertia about the center-of-gravity z-axis Izz measured in kg-mm2;
• has a moment of inertia about the center-of-gravity x-axis Ixx measured in kg-mm2;
• wherein Izz and Ixx are related to the above ground center-of-gravity location Zup by the equation:
• Ixx+Izz≥20·Zup+165;
• and
• wherein the golf club head has a balance point located on the face and the club head has a coefficient of restitution (COR) of no less than 0.80 as measured at the balance point on the striking face, and a characteristic time measured at a geometric center of the face of no less than 218 microseconds;
• a volume of the golf club head is less than about 210 cm3.
