1. A golf club head comprising:
a golf club body having a face, a crown and a sole together defining an interior cavity, the golf club body including a heel portion and a toe portion and having an x, y and z axes which are orthogonal to each other having their origin at USGA center face,
wherein the golf club head has a volume of at least 420 cm3,
wherein at least one of the sole or the crown is at least in part a composite material,
wherein the x-axis is tangential to the face and parallel to a ground plane,
wherein negative locations on the x-axis extend from the USGA center face to the toe portion,
wherein positive locations on the x-axis extend from the USGA center face to the heel portion,
wherein negative locations on the z-axis extend from the USGA center face to the sole,
wherein positive locations on the z-axis extend from the USGA center face to the crown,
wherein a center of gravity of the golf club head with respect to the x-axis (CGx) is oriented from about 0 mm to about −10 mm;
wherein the center of gravity of the golf club head with respect to the z-axis (CGz) is positioned below the USGA center face;
wherein a Delta 1 of the golf club head is greater than 20;
wherein a moment of inertia about the z-axis is greater than 400 kg·mm2;
wherein the golf club head has an alignment feature delineating a transition between at least a first portion of the crown having an area of contrasting shade or color with a shade or color of at least one of the face and a second portion of the crown; and
wherein the alignment feature has:
a Sight Adjusted Perceived Face Angle (SAPFA) of from about −2 to about 10 degrees; and
a Radius of Curvature (circle fit) of from about 300 mm to about 1000 mm.
