Let's break down the newest hybrid design from Easton: the 2017 Easton Z-CORE Hybrid BBCOR Baseball Bat: The barrel is composed of Easton's high-grade Hyperlite Matrix (HMX) alloy combined with the Z-CORE internal core technology to deliver the biggest sweet spot and longest aluminum BBCOR barrel in baseball. With that combination, you can expect a massive hitting surface, unmatched performance, and more ping in every swing! On the other end, the handle is made up of SIC black carbon composite material. Easton's SIC material strengthens the handle while eliminating any negative vibration for an optimized feel during every at bat. These two halves are combined with the patented two-piece ConneXion technology to maximize energy transfer, create more flex, and add more trampoline effect. In addition, the Z-CORE Hybrid features the second highest swing weight index in the 2017 BBCOR Power Brigade lineup for a slightly end loaded swing weight and more mass behind the ball at impact. Easton: The King of Ping!
