Abstract
The present invention provides a ball bat having a knob, a handle portion extending from the knob, a barrel portion extending from the handle portion, and an inflatable grip disposed on the handle portion. The inflatable grip includes an inflatable tubular sleeve through which the handle portion extends, an inflator in fluid communication with the inflatable tubular sleeve for pumping air into the inflatable tubular sleeve, and a release valve in fluid communication with the inflatable tubular sleeve for releasing air from the inflatable tubular sleeve. The ball bat according to the invention allows a batter to selectively pressurize the inflatable tubular sleeve to adjust the rigidity and size of the grip, which improves batter comfort and reduces the amount of shock and vibration transferred from the ball bat to the batter's hands.
