Combat 2014 Wanted 10 Fastpitch Softball Bat Combat's twopiece bats have all the advantages of a twopiece model without any of the disadvantages other competitors face. The design is centered on Combat's exclusive Handle Isolation Technology (HIT). HIT uses polymetric viscoelastic dampened to isolate the ultralight handle from the high performance doublewall barrel. This exclusive material stiffens under load so the barrel responds quickly to your swing, but then softens to absorb vibration feedback, eliminating vibrations before they reach your hands. Designed and Approved by Lisa Fernandez and Kelsey Bruder. Bat Specifications Drop: 10 Fastpitch bat. Barrel: 2 1/4. Certified: Approved for play in USSSA, NSA, ISA, ISF, ASA. Available Sizes: 32in 22oz,33in 23oz,34in 24oz.
