First, a run-down of the particulars:
  • A limit of 108 pounds is observed for this list.
  • The inception of the title was the first fight in the division between the two undefeated Atomweight fighters.
  • Recordkeeping and regulations (weight classes) were notoriously bad for Women’s MMA.  As a result, we may update this list if new info presents itself.
