This Super Z1000 is constructed as a 2-piece and crafted with 100% composite material. The barrel is made with Louisville Slugger's high end LS-2X composite, featuring a quicker break-in design for maximum performance right out of the wrapper! The IST XStiff handle gives this bat a stiffer feel for increased energy transfer, while also keeping the bat from feeling too whippy as you swing through the hitting zone. This bat is made end-loaded, as extra weight was added to the end of the barrel for increased power potential.
