The Baum bat is a wooden bat with a Composite center.
Unlike a normal wooden bat that you can only hit on a certain spot on the bat head, the Baum bat allows you to hit anywhere on the bat head without breaking like a normal wood bat.
Since I’ve had my Baum bat, I can feel my swing improving with the way the weight is distributed through the bat. The Baum bat feels lighter the a lot of other bats it’s size and weight.
