A golf club head comprising a body and a plurality of carbon tubes is disclosed herein. The body comprises a face section, a sole section with a protrusion extending upward and a crown section. The body defines a hollow interior. Each of the plurality of carbon tubes extends from the crown section to the protrusion of the sole section.

A golf club head includes a body having a recessed channel formed in an outer surface. A weight assembly that includes a weight at least partially disposed within the recessed channel, a cover extending at least partially over the recessed channel, and a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The weight is slidably engaged with the cover and the cover is positionable in at least an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is selectively slidable within the recessed channel, and a locked configuration whereby the cover is at least partially disposed within the recessed channel and the weight is secured within the recessed channel. The weight moves with the cover between the unlocked configuration and the locked configuration.

A golf club head includes: a head body that includes a cavity; a weight that is detachably attached to the cavity; and a cover that is openably and closably attached to the head body and that covers at least a part of the cavity when the cover is in a closed state. The weight is attached to the cavity in a state where the weight is slidingly movable in the cavity. In the closed state, the cover applies a pressing force to the weight. The weight may be fixed to the cavity by a static frictional force increased by the pressing force. The cavity may form a slide groove.

Disclosed herein is a golf club head comprising at least one crown opening and at least one crown insert attached to the body and covering the at least one crown opening. The golf club head further comprises at least one sole opening and at least one sole insert attached to the body and covering the at least one sole opening. The golf club head additionally includes at least one weight member configured to clamp first and second ledges at selected locations along a sliding weight track. The golf club head also comprise a coefficient of restitution (COR) feature located on the sole of the golf club head. The at least one crown insert is formed from a composite material having a density between 1 g/cc and 2 g/cc. The at least one sole insert is formed from a composite material having a density between 1 g/cc and 2 g/cc.

A golf club head includes a body having an outer surface and a recessed channel defined in the outer surface of the body. A chamber is defined at one end of the recessed channel. The golf club head also includes a weight assembly having a weight at least partially disposed within the recessed channel and configured to slide therein. A cover having a first end and an opposite second end, the second end including a projection, and a fastener coupling the first end of the cover to the body. The fastener secures the first end of the cover to the body while the projection of the second end of the cover engages with the chamber of the recessed channel to retain a position of the weight within the recessed channel between the first end and the second end of the cover.

A cavity back iron type club head includes a striking plate having a substantially planar striking surface and a rear surface defining a thickness therebetween. The rear surface defines a striking plate rear cavity region. A perimeter support is coupled to a peripheral portion of the striking plate. The surface area of the striking surface is related to the club head loft angle by the equation SSA≥14.4(L)+2875, where SSA is the surface area of the striking surface in units of square-millimeters and L is the club head loft angle in units of degrees.

A golf club head includes: a body including: a striking face having a lower edge and an opposite upper edge; a sole extending from the lower edge; and a crown extending from the upper edge, wherein the striking face, the sole, and the crown, define at least part of an outer surface of the body; a recessed channel formed in the outer surface; and a weight assembly including: a weight; a cover extending at least partially over the recessed channel; and a threaded fastener configured to engage with the cover and to move the cover between a locked position and an unlocked position, wherein the weight is slidably engaged with the cover such that the weight moves with the cover between the locked position and the unlocked position, and wherein the weight assembly is configured such that the weight is slidable relative to the cover when the cover is in the unlocked position.

A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.

Disclosed herein is a golf club head comprising at least one crown opening and at least one crown insert attached to the body and covering the at least one crown opening. The golf club head further comprises at least one sole opening and at least one sole insert attached to the body and covering the at least one sole opening. The golf club head additionally includes at least one weight member configured to clamp first and second ledges at selected locations along a sliding weight track. The golf club head also comprise a coefficient of restitution (COR) feature located on the sole of the golf club head. The at least one crown insert is formed from a composite material having a density between 1 g/cc and 2 g/cc. The at least one sole insert is formed from a composite material having a density between 1 g/cc and 2 g/cc.

Sporting articles are provided that have improved aerodynamics, including a golf club. The golf club includes a head, the head including a plurality of dimples, configured to decrease drag of the head when swung by the user, and a chamber defined in the head, the chamber including one or more weights movable within the chamber to adjust a balance of the golf club head. The movable weights enable adjustments to be made to compensate for changes in characteristics of the golf club associated with the increased aerodynamic efficiency.
