The Marucci CAT X Baseball Bat features both BBCOR and USSSA certifications and is a single-piece alloy bat with a well-sized barrel and excellent feel. Its multi-variable wall Ring-Free barrel provides consistent power across leagues, while the stiff S-40 composite handle offers a balanced swing weight and reduces vibration for improved comfort. The CAT X also features liquid-gel in the knob which reduces vibrations throughout the hands.
