The Worth MACH was designed for players looking for the ultimate combination of barrel size and bat head speed. We created the MACH 1 Cobra Jet XXL with X434 barrel technology which increases the bats durability and maximizes performance. The MACH 1 COBRA JET features a full size 13.5” barrel so players have an enlarged hitting surface to combine with the XXL 1oz weighting for player preference. Lastly, we added a Opti-Grip Knob which is a smaller knob design for players who like to wrap their hand around the knob during their swing.
