The Worth AMP is back and ready to help players AMP up their swing this softball season! The AMP is a one-piece bat made from performance alloy. This alloy allows for thin shells and walls to create maximum trampoline effect off of the bat. With improved feel and performance, the AMP is ideal for players looking to maximize swing speed, durability, and hitting performance. The AMP uses Whiplash Technology to create a 30 thinner taper for reduced swing weight to help players increase the speed of their swing! As a result, players improve their power due to hitting the ball harder! In addition, the AMP features balanced loading that makes it one of the most true-to-weight bats on the market. Balanced bats are primarily used by players seeking maximum bat consistency and control at the plate. Worth: A Century of Excellence! The Worth AMP is approved for play in ASA, NSA, USSSA, ISF and ISA. 34 / 26 oz.
