Baseball bat
The present invention proposes a baseball bat, which comprises a hollow handle region extending along an axis and including a connection section; and a barrel region extending along the axis and connected with the connection section. The barrel region has thermoset resin layers and at least one flexible chain polymer layer, which exists within the thermoset resin layers, so that the barrel region does not harden after shape forming. The barrel region of the baseball bat can absorb vibration during batting and improve the stability of the batted ball.
