The original "bat that bends" the Demarini Big Barrel Vexxum Baseball Bat 28/19.5 features Half & Half Technology which combines a Flex-Tuned composite handle with an aluminum alloy barrel. Virtually indestructable, the two piece system of the DeMarini Vexxum Baseball Bat flexes before impact, exploding with a burst of ball-launching energy. The new Flex-Tuned Composite Handle for increased power and 10% more durability and a Long Barrel profile for a larger hitting surface than other bats in this catagory as well as TT Technology for maximum performance throughout the barrel.
