This gives the bat a seven-variable wall design. Since it's a one-piece aluminum bat, you'll notice a faster swing speed and a more traditional balanced feel. Key features of the CAT7:

  • Places 2 oz of weight below the player's hands, which lowers the swing weight of the bat and lowers the MOI.
  • AV2 Knob is patented and offers a better feel and less negative vibrational feedback.
