Stealth Model The stealth bats are constructed of laminates from hand selected and graded native hardwoods. The patented "Boa" reinforcement on the handle significantly reduces breakage. The choice of wood for the barrel has proven to greatly reduce the chipping and flaking characteristic in one-piece ash bats. This model has NCAA approval for all levels of play and is also approved by MLB for rookie and short season play. The Stealth bat is available in 31" 32", 33" and 34" lengths with weight drops up to -3 ounce. Please choose your bat length and weight. Note: the 34" is only available in even, -1, -2 weights.
