1. A golf club head, comprising:

  • a body, defining an interior cavity and comprising;

    a sole portion, positioned at a bottom portion of the golf club head, wherein the sole portion comprises one or more sole openings configured to receive one or more sole inserts, the sole portion comprising the one or more sole inserts, which cover the one or more sole openings;

    a weight track having a track length between about 30 mm and about 120 mm, wherein the weight track is positioned in the bottom portion of the golf club head and configured to receive one or more slideably adjustable weights, wherein movement of the one or more slideably adjustable weights adjusts a center of gravity of the club head;

    a crown portion, positioned at a top portion of the golf club head, wherein the crown portion comprises a crown opening and a recessed ledge around the crown opening configured to receive a crown insert and the crown insert is secured to the recessed ledge and covers the crown opening;

    a skirt portion, positioned around a periphery of the golf club head between the sole portion and the crown portion;

    wherein the one or more sole inserts are made of a composite material having a density between 1 g/cc and 2 g/cc;

    a face portion having a variable thickness, coupled to the body at a forward region of the body and comprising a striking face with an area of at least 3500 mm{circumflex over ( 

    )}2 and a maximum height from a ground plane of at least about 50 mm;

    wherein there is a face-to-crown transition where the face portion connects to the crown portion proximate the forward region of the body and a skirt-to-crown transition where the skirt portion connects to the crown portion proximate a rearward region;

    wherein in a y-z plane passing through a club head origin the crown height continuously increases starting from the face-to-crown transition up to a local maximum; and

    wherein;

    the golf club head has a peak crown height, from the ground plane, of at least about 60 mm;

    a volume of the golf club head is at least about 370 cm3;

    a location of a center-of-gravity of the golf club head is at a minimum distance (Zup) away from the ground plane;

    a z-axis moment of inertia of the golf club head about a z-axis, passing through the center-of-gravity of the golf club head and perpendicular to the ground plane, is greater than about 300 kg-mm2; and

    when the golf club head is in the address position on the ground plane;

    a crown height of the golf club head, at a head origin y-axis coordinate of zero, is less than 65 mm; and

    a crown height of the golf club head, at a head origin y-axis coordinate of 90 mm, is less than about 32 mm.
