The future of bat technology starts now. The DeMarini VIZION is the first adjustable Slowpitch bat offering four (4) different weight options all in ONE bat (26/27, 27/28, 28/29 & 29/30oz) thanks to AOD (Adjustable on Demand) technology in its End Cap. AOD is a removable endcap system comprised of an interlocking multi-weight end cap and knob design, allowing players to create a multitude of weight balance points on a single bat. What this means is that the DeMarini VIZION can be adjusted for whatever the situation calls for. No more needing different bats for different situations or player preference, this bat is a one-size-fits-all. Don't be fooled. Just because this bat features AOD, it doesn't mean we forgot about the rest of the bat's features. Built on the ST2 Platform with a S.ONE Composite Barrel, the VIZION gives you the control and power you need to dominate the USSSA diamond. The First Fully Customizable weighted bat design from the first company to do Custom Bats. Enjoy.
