Easton MAV1 EBB4MAV3 BBCOR -3oz is engineered with a newly developed Extra-Long Draw alloy processing system that creates a thinner barrel wall across more of the sweet spot -- 7% thinner than pervious Easton 1-piece alloy bats -- giving you the maximum allowed performance across virtually the entire hitting surface. In addition, the MAV HP alloy is engineered to give you an ultra-balanced swing weight, 50 MOI points lighter than previous models. On top of that, the sleek handle taper gives you more barrel control, allowing you to deal damage on any pitch in any location.
