Embodiments of golf club heads with turbulators and methods to manufacture golf club heads with turbulators are generally described herein. Other embodiments may be described and claimed.

A mouthguard carry case (10) comprising: an outer shell (12) having a hollow interior defined by an open top, an open bottom and a plurality of side walls (14). The mouthguard carry case (10) also comprises an inner shell (18) having a hollow interior defined by a top wall (20), a bottom wall (22) and plurality of side walls (24). The inner shell (18) is slidably received within the hollow interior of the outer shell (12) and is movable between an open position, and a closed position. Advantageously the mouthguard carry case (10) can be opened and closed in one hand, and is fully ventilated to promote drying and inhibit the growth of oral bacteria.

A golf club head comprises a body including a top and a bottom and a hosel connected to the body. The body comprises a forward face defining a leading edge and an opposing rearward facing surface defining a trailing edge. At least one weight shifting element is positioned on the rearward facing surface. A sole extends between the leading edge and the trailing edge and defines a center portion, a first end surface and a second end surface. A static bounce angle is equal to an effective bounce angle when the center portion is square with the ground, and the effective bounce angle is greater than the static bounce angle when the center portion is not square with the ground and the second end surface is positioned away from the ground.

A golf club includes a golf club head having a body defining an interior cavity. The body includes a sole, a crown and a skirt positioned around a periphery between the sole and crown. A face defines a forward portion of the club head and includes a striking surface width and a hosel defining a hosel bore. A channel and a recessed port are positioned in the sole. The channel extends substantially in a heel-to-toe direction. A sleeve is mounted on a tip end of the golf club shaft and is adapted to be inserted into the hosel bore. A fastener has a shaft portion extending through a passage and a head portion located in the recessed port. Selectively attaching the sleeve adjusts at least one of a loft angle and a lie angle of the club head.

A sport ball includes a casing that includes a plurality of joined panels and defines a cavity. The casing includes at least a first panel having (a) a first layer positioned to form a portion of an exterior surface of the sport ball, (b) a second layer disposed adjacent to the first layer, and (c) a third layer disposed adjacent to the second layer. The first panel defines a first indentation and a second indentation spaced apart from the first indentation. The first indentation has a first depth and the second indentation has a second depth that is less than the first depth. The first depth is from 0.5 times to 4 times larger than the second depth. The sport ball also includes a bladder disposed within the cavity.

A golf club head for a driver is disclosed. The golf club head includes a face portion and a rearward end portion. An upward facing surface in a crown portion of the golf club head curves up towards the rearward end portion to keep airflow from separating from the crown portion. A downward facing surface on a sole portion of the golf club includes an airfoil that helps keep air stuck to the sole portion of the golf club head. The airfoil portion extends across a substantial entirety of the width of the golf club head.

This invention provides sports ball having asymmetrical traction and/or asymmetrical surface structure. The asymmetrical traction is useful for differentially controlling ball spin and trajectory height as the ball is projected from a pitching machine. The asymmetrical surface structure is useful for differentially controlling the lateral component of the ball's trajectory. Optionally, the ball is a pitching machine ball. The method also provides a method of projecting the ball from a pitching machine.

A swing speed training club includes a shaft having a proximal end and a distal end; and a head portion affixed to the distal end of the shaft and having a body having a proximal end and a distal end. The head portion is configured to produce a distinctive sound when the head portion is swung through the air at the distal end of the club shaft at a suitable speed.

A golf club head includes a head main body, and a toe-side component. The head main body includes a striking face, a hosel portion defining a shaft center line, and a mounting portion for mounting the toe-side component on a toe side with respect to the shaft center line. The toe-side component is fixed to the mounting portion removably. When the toe-side component is removed from the mounting portion of the head main body, a head projected area in a front view of the golf club head becomes smaller.

A golf club incorporating a plurality of projections extending from on the crown section.
