The Super Z Wounded Warrior is a limited edition slowpitch softball bat with a portion of the proceeds going to the WWAST, which is the Wounded Warrior Amputee Softball Team. Louisville Slugger constructs the SUPER Z Wounded Warrior Slowpitch Softball Bat as a 2-piece made out of 100% composite material, giving you great durability and limited vibration so you can maximize your potential at the plate! The iST Technology makes the Super Z WW extra stiff, giving you a very sturdy-feel without excess flex as you swing through the hitting zone.
