Abstract
A ball bat includes multiple layers of one or more composite materials. One or more 'integral shock attenuation' ('ISA') regions, which have a substantially lower axial stiffness than neighboring regions in the bat, are provided to attenuate shock waves resulting from an “off-center” hit. ISA regions may be incorporated into the transition region, the handle, and/or the barrel of the ball bat to provide vibration damping, shock attenuation, stiffness control, increased flexure, and/or improved feel.
