Aerospace technology, which gave Louisville Slugger most of the
aluminum alloys used in the manufacturing of bats, continues to be an
inspiration to Louisville Slugger engineers. TPX Armor features a
matrix material coating, a proprietary combination of metal and
ceramic, which is also used in jet engines. The metal portion of this
ultra had coating gives you the performance you expect, while the hard
ceramic reduces wear and tear experienced in typical field play. This
bat meets all College and High School Bat Standards.
