A bat includes a substantially tubular frame, a substantially tubular body and at least one sheet. The frame extends along a longitudinal axis. The frame has a handle portion and a primary hitting portion. The body is coaxially aligned with the hitting portion of the frame. The sheet has a proximal edge, a distal edge, and first and second side edges. The sheet is coupled to at least a portion of one of the hitting portion of the frame and the body such that the first and second edges each extend from the proximal edge to the distal edge along a path that is substantially non-parallel with the longitudinal axis.
