Long Barrel Design ? The Long Barrel design Maximizes the bat?s hitting surface by expanding the barrel?s area of contact to have the biggest allowable diameter. * SC4 Alloy Barrel ? DeMarini?s proprietary aluminum extrusion provides a thickness tuned wall that reaches down the entire length of the barrel to create a wicked sweet spot that can stand up to each crushing blow. * Internal Rails Hybrid Handle ? The vibration reduction of the Rails system turns the entire barrel into one big sweet spot. It?s constructed with two distinct materials * Half+Half Construction ? This two-piece hitting system was introduced by DeMarini to create a large, more responsive sweet spot by silencing vibration, flexing before impact and re-coiling with a burst of ball launching energy * Great bat for travel and senior leagues. A softer outer material that cushions impact along with strategically inserted support rails that add stiffness to maintain a consistent and optimal swing.
