Abstract: A swing weight apparatus includes a swing weight body and at least one insertable weight. A swing weight body includes a bottom layer, a middle layer, and a top layer. Each layer preferably has a perimeter which has a substantially curved portion and a substantially straight portion. The substantially curved portion of each layer are attached to each other. The bottom layer and the top layer are releasably joined to each other on the substantially straight portion with a removable fastener such as a zipper or a hook and loop fastener. Each insertable weight preferably includes a quantity of weighted material which is retained between two outside layers. The perimeter of each insertable weight is shaped to fit between the middle and top layers. The perimeters of the two weighted layers are attached to each other with the weighted material therein. Preferably, a hosel strap is attached to one end of the substantially straight portion.
