Our Heat Roll with Progressive Pressure is the BEST way to break in any baseball or softball bat - new or used, composite or alloy. Our professional process will add 20-40ft of additional distance on your solid hits by breaking in your bat completely and evenly, allowing the entire barrel to flex in unison upon contact.
