The J-grip function of this bat helps correct swing and prevent injuries. The rounded grip end is designed to be between a J-grip and a standard grip. The hold has been significantly improved. It can be expected to be effective in preventing injuries to the wrist and the ulnar bone. Swinging without feeling any discomfort naturally leads to an inside-out swing, and furthermore, allows for a "level swing" that enables you to hit the ball with a line drive. ● Material: Carbon composite ● Color: White & Green ● Size: 79.5cm, average 590g ● Semi-top balance ● For softball 2-gou (size) Good Design Award Winner I liked the exquisite length, balance, material, and unique hitting sound and used it.
