STAK Bat Power/Speed Combo

The ExploSwing STAK Bat Overload /Underload Bat Speed system is the best way to increase and maintain bat speed in your swing! Increase your bat speed, swing strength, exit velocity and power with the StackBat Overload / Under Load system!


Each bat is made from pro grade yellow birch wood to give the bat more "flex" while having the durability of maple. They are also steel compressed and wrapped with carbon fiber sleeving for extra durability. These are safe to use with regular baseballs and heavy sand filled plyo balls up to 16oz. off of tee work, side toss, and front toss. Not to be used with regular baseballs for overhand batting practice, pitching machines, or live game pitching.
