The 2021 Monsta TKO Sinister Blackout USA/ASA Slowpitch Softball Bat couples the M2 technology with Monsta’s patented FIB. The M2 Composite has allowed Monsta to create the lightest and highest performing USA bats in the game, and allows for many weight options. It has also expanded the size of the sweet spot compared to previous FIB designs, while reducing the break-in period. The 2021 Monsta TKO Sinister Blackout offers a balance of power and control, along with the trampoline effect of the FIB for great exit speed and distance.
