Abstract

A softball or baseball bat with modified restitution characteristic is provided. The bat can comprise a substantially rigid core coupled with a single or multi-piece sleeve. The core can comprise a tip end, a barrel taper, a handle taper, and a handle. The sleeve can slide over the handle portion and can be pressed, molded, or adhered to the barrel taper. The resilient sleeve can be sized and shaped such that the sleeve portion is substantially the same diameter as the tip end. The sleeve can comprise a material capable of impact absorption. The sleeve can have a composite structure with inner and outer sleeve components. The sleeve can further comprise a cone to taper the sleeve in the handle taper portion of the bat. The material and thickness of the sleeve and the core can be varied to meet applicable restitution requirements.
