A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

A golf club comprises a tubular shaft and a weight member. The shaft has a first end having a first inner diameter and a second end on the opposite side thereof. The weight member is attached to the first end, and comprises an insertion portion disposed in the hollow of the shaft, an engaging portion engaged with the first end on the outside of the shaft, protrusions protruding radially from the insertion portion. Each protrusion has a tapered portion in which the radially outwardly protruding height from the insertion portion is decreased toward the second end. The length of each tapered portion is more than 50% of the maximum length of the protrusion, both measured in the shaft axial direction.

An object of the present invention is to provide a golf club grip having high tensile strength in the outer layer and little entrainment of air between the outer layer and the inner layer. The present invention provides a golf club grip comprising a cylindrical portion composed of a cylindrical inner layer and a cylindrical outer layer covering the inner layer, wherein a ratio (E′.sub.23/E′.sub.60) of a storage modulus (E′.sub.23) at 23° C. of the outer layer to a storage modulus (E′.sub.60) at 60° C. of the outer layer, measured with a dynamic viscoelasticity measuring apparatus under measuring conditions of an oscillation frequency: 10 Hz, a strain amplitude: 0.05%, and a tensile mode, ranges from 1.20 to 1.32.

A putter type golf club includes a putter head with a ball striking face, a shaft attached to said putter head, and an elongated grip attached to the shaft. The elongated grip includes a lower section, an upper section and a cap forming a butt section at the upper area of the grip, the lower section of the elongated grip including a shaft opening at a lower end thereof, the lower section of the elongated grip structured to accommodate the hands of a golfer, the upper section of the elongated grip having a leading edge located in a direction toward and closest to an intended target with the putter head in a normal position prior to executing a normal putting stroke.

A golf club assembly includes a golf club and a cover for the golf club handle. The cover includes a panel having a first plurality of apertures on a first edge of the panel and a second plurality of apertures on a second edge of the panel. A fastener is on a top edge of the panel. Lacing extends through the first plurality of apertures and the second plurality of apertures. The cover has a first mode in which the lacing extends from one of the first plurality of apertures to the second plurality of apertures to form the panel into a cylinder shape. The cylindrical shape is installed over a grip portion of the golf club. The cover has a second mode in which the lacing does not extend through the plurality of apertures and the cover defines a lay flat orientation.
