Depending on barrel material, we utilize several different technologies to achieve one sided hitting: Composite: Our composite bats use ++ technology. ++ uses additional layers of carbon fiber in the hitting zone, literally making the barrel thicker where the ball strikes. To maximize the performance, we added an asymmetric ‘C’ shaped slip plane which makes this thick hitting wall perform like two very hot thin walls. Alloy: We use military grade LP Scandium Alloy that has an incredibly high strength to weight ratio. We then use a proprietary combination of swedging and machining to put pop and durability in the hitting zone, and shave weight everywhere else. One-sided hitting lets us maximize pop, durability and balance in a single bat.
