ThumbPRO makes a thumb guard that helps improve grip and reduce vibration from impact.

Baseball's #1 thumb guard. Top-rated used by pro hitters worldwide. ThumbPRO® was founded to address a long-standing gap in baseball and softball: real protection for the thumb against bat sting and injury. 

Craig First, an engineer by trade, inventor, and lifelong baseball fan, developed a patented contoured thumb guard that protects the thumb joint, absorbs impact, and supports proper hand mechanics without altering the swing. Every ThumbPRO® is made in the USA with premium materials and consistent, reliable quality.

ThumbPRO® is a small, family-run company based in Massachusetts, dedicated to designing protective gear that is purposeful, durable, and trusted by athletes at all levels. 

Our mission is to raise the standard for hand protection in the game through thoughtful engineering and products that are built to last.
