2015 Combat Centenarian Balanced 1.21 8FT: Combat's patented Blended Fiber Technology blends several different types of fiber at varying angles to result in durability, vibration absorption and maximum bat performance. Seamless Construction: Combat's Seamless Construction refers to thousands of continuous strands of fiber which run through the length of the bat. There are no cuts, splices or 'weak spots'. ACT: With Combat's Anisotropic Composite Technology, the stiffness and strengths are varied along the handle and across the barrel. PMT: Precision Molding Technology is an exclusive patent pending process that uses computer-controlled tooling to define both the inner and outer barrel diameters with precision control and accuracy.
