We have collaborated with Jim Bradley to create our very own Pro Ball! They are available in 5x8/20cm and 6x9/25cm. The Pro ball is soft on your hands and light to hit allowing you to hit for longer and that is why it's the fastest ball in the world. The Pro ball is made from hand picked, very light Italian sheep skin leather, which makes it a very fast hitting ball. Ours have the reinforced loop and rivets. These bags are exclusive through The Thrasher House only. Our trim is different from the Jim Bradley trim from the loop length to the material. Made by a speed bagger for speed baggers!
