Abstract: The present disclosure is related to a snap system including a mating component and a snap component that connect by means of a snap fit or otherwise. The mating component simplifies the assembly process by combining a structural component and an attachment point. The snap component is associated with a removable component that mates with the attachment point of the mating component. The snap system includes a mating component that combines a structural component to secure a material and an attachment point to secure a snap component. The design of the structural component allows the mating component to be used with a variety of materials having a variable thickness. The mating component is a versatile feature as the structural component self-adjusts to the thickness of the material provided. The snap system decreases the amount of components necessary for manufacturing which may decrease the cost and improve the visual appeal.

Abstract: Described herein is a hollow body iron-type golf club head having a sole and ballast configured to relieve stress within a forward region of the sole. In a first configuration, the golf club head comprises a ballast undercut for relieving stress. In other configurations, the ballast undercut is combined with additional stress relief features, such as a cascading sole near the face sole juncture, for further reductions to face thickness. In further configurations, the ballast defines a recess for receiving a ballast weight having a density greater than the body, thereby improving mass properties of the golf club head.

Abstract: Embodiments of a strap assembly system for a golf bag are described herein. The strap assembly system can be converted between a single-strap configuration or a double-strap configuration. The strap assembly system comprises a first strap, a second strap, and a back puck. The back puck comprises first and second attachment openings for securing the first strap. The back puck further comprises first and second side openings that define a linear pathway and are configured to receive the second strap. The second strap can move freely along the linear pathway.

Abstract: A golf club head comprising a shaft sleeve with a shaft sleeve coupler set, a sleeve outer wall, and a cap. The shaft sleeve coupler set comprises four couplers protruding from the sleeve outer wall. Each of the four couplers comprises an arcuate surface. The golf club head comprises a hosel bore. The shaft sleeve is configured to be received by the hosel bore. The shaft sleeve and the hosel bore are non-coaxial.

Abstract: Embodiments of golf club heads having transition profiles to reduce aerodynamic drag during a swing are described herein. In some embodiments, a golf club head includes a crown transition profile having a first crown radius of curvature, a sole transition profile having a first sole radius of curvature, and a rear transition profile having a rear radius of curvature.

Abstract: Embodiments of a golf club head with a textured strikeface and methods to form said club head through laser shock treatment are generally described herein. The golf club head can comprise a body and a strikeface. The strikeface has a textured front surface, with an array of indentions. Each indention can have a footprint area of between 0.01 ?m2 (1×10?8 mm2) to 250,000 ?m2 (0.25 mm2). The textured front surface can affect the spin imparted to a golf ball upon impact. Other embodiments may be described and claimed.

Abstract: A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.
