The Sledge is a unique training tool designed for soft toss, short BP and tee hitting. Having a barrel made from a durable nylon composite allows the Sledge to give the hitter instant feedback telling them whether or not they are hammering the sweet spot. With the feel of wood, strength of airplane grade aluminum, and the balance of a traditional bat, the Sledge not only builds strength and develops hand/eye coordination, but teaches the hitter proper mechanics through the hitting zone. Sizes: 31"/39oz., 32"/40oz., 33"/41oz., 34"/42oz.
