Easton's O-Zone optimal hitting zone technology increases stiffness along the barrel, thereby widening the bat's sweet spot. Combined with the SV12's forged end and concave Mother Load pre-loaded end cap, this will improve the power and distance of your hits. Like many of Easton's softball bats, the SV12 has an ultra-thin 29/32" handle, with the Pro-Tack grip they save for their premium offerings. The SV12 conforms to all major softball association Bat Performance Standards, and is therefore approved for play in the ASA, USSSA, NSA, ISA, SSUSA and ISF.
