In one embodiment the golf club head includes three main components, a frame component, a rear cap component, and a striking plate. In another embodiment the club head may also comprise a front component, which is manufactured as a single unitary piece, and a rear cap component. The front component may also be overmolded by a thermoplastic polymeric outer portion which may or may not cover the striking face and which provides additional reinforcement at the load bearing sections of the club head and allows a more facile connection to the rear cap component. In another embodiment, a club head having a main body, crown insert, sole insert and metal face plate frame is formed by forming the sole insert and crown insert from a polymeric material using a thermoforming or thermosetting process and then injection molding the main body over the sole insert, crown insert and metal face plate frame.

Embodiments provide a lacrosse head having a pocket stringing system that includes attachment members that allow for rapid, direct attachment of a pocket to the head. A lacrosse head may include cleats protruding from the sidewalls at a rearward portion of the pocket area nearest the juncture, sidewall hooks protruding from the sidewalls at a forward portion of the pocket area forward of the rearward portion, and scoop hooks protruding in the forward direction from the front face of the scoop. Each cleat may have a rearwardly-projecting arm and a forwardly-projecting arm. Each sidewall hook may have a rearwardly-projecting arm. A first scoop hook may tension a pocket toward a first sidewall hook on a first sidewall, and a second scoop hook may tension the pocket toward a second sidewall hook on a second sidewall, so as to form a ball channel in the pocket.

Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.

Described herein are embodiments of golf club heads having a balance of the following parameters: a low and back club head center of gravity position, a high moment of inertia, a large Ixy product of inertia, and low aerodynamic drag. Methods of manufacturing the embodiments of golf club heads having a balance of club head center of gravity position, moment of inertia, product of inertia, and aerodynamic drag are also described herein.

Disclosed herein is an iron-type golf club head that comprises a body, made of a first material having a first density. The iron-type golf club head also comprises a weight located within the internal cavity. The iron-type golf club head further comprises a filler material that has a density no less than 0.21 g/cc. The filler material has a mass no less than 2.5 grams and no more than 8 grams. The internal cavity has an internal cavity volume ranging between 5 cc to 20 cc. A ratio of the internal cavity volume to external club head volume ranges between 0.14 and 0.385. The internal cavity has a minimum front-to-back depth above a midplane of the golf club head of no less than 1.4 mm and a maximum front-to-back depth of the internal cavity above the midplane of the golf club head is no more than 13 mm.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head may include a body portion, and an internal mass portion comprising a material having a greater density than a material of the body portion, a height in a top-to-sole direction, a depth in a front-to-back direction, and a width in a toe-to-heel direction. The distance between the internal mass portion and a toe portion edge is substantially less than the distance between the internal mass portion and a heel portion edge. The volume of the internal mass portion increases in a top-to-sole direction, and the height of the internal mass portion is greater than the width of the internal mass portion. Other examples and embodiments may be described and claimed.

Embodiments of golf club heads with apertures and methods to manufacture golf club heads are generally described herein. In some embodiments, a golf club head comprises a face portion, a back portion generally opposite the face portion, a heel portion extending between the face portion and the back portion, a toe portion opposite the heel portion and extending between the face portion and the back portion, and a crown portion extending between the face portion, the back portion, the heel portion, and the toe portion, the crown portion comprising a plurality of crown aperture. The crown portion comprises a first region and a second region, wherein the first region is nearer to the face portion than the second region, the first region and the second region are separated by a bell-shaped curve. The bell-shaped curve is located a distance D1 from the face portion and the second region comprises a recess portion. The plurality of crown apertures is defined within the recessed portion. In some embodiments, the golf club head comprises both metal and fiber-based composite portions. In other embodiments, the golf club head comprises a plurality of sole apertures. Other embodiments may be described and claimed.
