We went back to the drawing board to improve last year’s Virus SL with this hot new design. The B2 has dynamically tuned bending to minimize handle vibrations for a great feel, soft barrel and maximum performance. Plus, Combat’s Variable Stiffness Technology produces a bigger sweetspot to take performance and feel to a new level. It has taken three years and thousands of hours of lab and field testing to design a bat worthy of the B2 logo.
