Sting Pad prevents palm bruising and stops the sting caused by hard hit balls! Made of shock absorbing gel material which dissipates and cushions the sting. Simply slide over index finger and it fits snugly against the palm. You won't feel it once the glove is on. Material is thick enough to protect, but thin enough not to interfere with catching. Prevents bruising and promotes healing of bruised palms. Fits both left and right handers.
