CENTURY BOB The Ultimate Sparring Dummy -  Develop great power, speed and accuracy! BOB is the perfect sparring partner. Lifelike in size, shape and feel, BOB's 'skin' is made of high-strength Plastisol so it's easy on your hands and feet, but tough enough to stand up to your harshest beating. BOB is great for practicing all your techniques. And unlike a real sparring partner, you can hit BOB full force and he'll come back for more. BOB's base can be filled with water or sand and weighs approximately 220 pounds when filled. Three height adjustments let you choose BOB's height - approximately 5'6', 6'0', or 6' 2' tall. BOB ships UPS oversize in two boxes.
