Using our new Paradox Composite, we"ve made a stronger composite that is shaped to perform softer. This makes for a bigger, hotter, more responsive sweet spot, which leads to consistently powerful swings. * Certification: ASA,USSSA,NSA,ISA,ISF * Half+Half 2-Piece Design * The Clutch End Cap dampens vibration for a smooth swing while keeping energy focused in the barrel so balls pop off with authority. * Stacked Double Wall Construction Two is better than one. The next generation of Stacked Double Wall creates a trampoline effect across the entirety of the barrel, optimizing performance.
