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.

An adjustable flexible device for use in training activities for stick-based sports. The device is comprised of a flexible material provided in a planar surface in a flattened and free state. The device includes a first end, a second end opposite the first end, and a slot located through the material and configured to securely receive the first end. In use, the device is wrapped into a cylindrical shape around the stick and secured in place via the slot and first end coupling. The device material properties provide that it is collapsible.

A grip device is disposed on a handle of a piece of equipment. The grip device includes a lower concave surface contacting the handle and a lower concave surface oriented away from the handle. An adhesive tape is wrapped around the handle and grip device in one embodiment. In another embodiment, an adhesive layer is disposed between the handle and grip device. The lower concave surface includes a first taper at an end of the grip device oriented toward a knob of the handle. The upper convex surface includes a second taper at an end of the grip device oriented away from the knob of the handle. The grip device bends to follow a curvature of the handle.

Provided is a customized golf club grip and methods of forming the same. The customized golf grips may include customization based on pronation and supination, a computer aided system for producing customized golf grips, a mold for producing a customized grip, a smart grip and use thereof for a customized grip, and the like.

Removable and re-attachable grips design to allow simple, fast changing of grips on shaft. The present disclosure relates in general to a re-changeable or interchangeable grip particularly suited for golf whose attachment requires three basic securing movements. In the first movement, heel components of the grip are first positioned onto the shaft, by either rotational torque or downward pressure, which result in securing the upper, proximal portion of the gripping sleeve onto the shaft. In the second movement, once the grip is situated and secured into place on the shaft, the grip is centered on the shaft by fastening toe components at the lower, distal portion of the grip sleeve onto the shaft, in the third movement, once both heel and toe embodiments of the grip have been fastened to the shaft, the internal core diameter of the grip sleeve is decreased in order to secure the grip to the shaft, such as by rotating or twisting the entire grip sleeve body.

Provided is an adjustable custom grip and method of forming the same are provided. The method of forming a customized putter grip includes orienting a first grip member having a first contact surface and a second grip member having a second contact surface of the customized putter grip in a predetermined orientation selected from a set of angles between the first contact surface and the second contact surface. The method may also include fixing the first grip member and the second grip member in the predetermined orientation. The method may further include coupling the customized putter grip with fixed first grip member and second grip member to a shaft of a putter. The custom grip provides for an anatomically, ergonomically custom putter grip to accommodate variations in human hands and other anatomical parts that affect the holding of a golf club grip.

Provided is an adjustable putter grip. The adjustable putter grip includes a first grip member coupled adjacent a first end of a putter shaft. A putter head is coupled to a second end of the putter shaft. The adjustable putter grip also includes a second grip member coupled to the putter shaft between the first grip member and the second end of the putter shaft. The first grip member and the second grip member are rotatable with respect to each other to adjust grip position, the second grip member is rotatable with respect to the first grip member to adjust grip position, or the first grip member is rotatable with respect to the second grip member to adjust grip position. A method of forming a custom grip or custom fitting of a golfer is also disclosed.
