Fastpitch softball bats have a 2 1/4 inch barrel. The younger players swing the light weight or -12, -11, or -10 drop length to weight ratio. The older players in high school or college swing the heavier -10 or -8 drop. Different lengths from 28 inches to 34 inches are made. Fastpitch Bats are stamped with the latest association decals on the bats for certification in tournaments and championship play. The same technology found in high end baseball bats are found, with composite materials, variable wall thickness, and adjusted weight balance. The barrels in fast pitch bats are longer and try to maximize the sweet spot for hits up and down the barrel.
