Abstract
A softball or baseball bat with modified restitution characteristics is provided. The bat can comprise a substantially rigid shell coupled with a single or multi-piece insert. The shell can comprise a tip end, a barrel, a handle taper, and a handle. The insert can be press-fit or adhered to the inside of the barrel of the shell. The insert can be a single or multi-piece design and can be single or multi-layered. The insert can comprise a material capable of impact absorption. Portions of the insert can be separated from the shell with a separation layer to improve restitution in certain areas of the bat. The insert can also comprise multiple layers that are separated from each other with a separation layer to improve restitution in certain areas of the bat. The material and thickness of the insert and the shell can be varied to meet applicable restitution requirements.
