Outside, professional, testing shows an increase of 10-15% in bat speed when using ThumbPRO.
The ThumbPRO performance thumb guard--Goes Righty, Goes Lefty
⚾️ Ergonomically engineered to fit your hand and stay in place swing after swing.
⚾️ Enables proper bat grip, unlocking your optimal swing by getting the bat up in your fingers and avoiding the “death grip” that can hold you back.
⚾️ Prevent bat sting without the fear of getting jammed.
⚾️ Made of shock-absorbing polymer.
Own the inside half of the plate and the entire strike zone with the best thumb guard you can get.
We suggest using a string or ribbon to measure around the circumference of the thumb--halfway between the base and the first knuckle of the thumb.
We recommend measuring for size in the way it will be used up at bat. If the players wears a glove at bat, measure with the glove on. If a glove is not worn, then measure without a glove on.
- L- 2 3/4" circumference (generally above 205+ lbs)
- M- 2 1/2" circumference (generally 130-205 lbs)
- S- 2 1/4" circumference (good for Youth and Adults under 130 lbs)
This is a general recommendation. Some like a looser fit and others prefer a snug performance fit.
