This water-filled punching bag stands 28 in tall and 21 in across, and the difference shows the moment you hit it. Water shifts inside the Pvc body on impact, so the bag absorbs the shock that a packed bag sends straight back through your wrists, while its high-rebound shape returns to position quickly enough to keep a combination going. Filling to the recommended 70 to 80 percent gives the balance of give and resistance most strikers are looking for.The hanging chain adjusts, so the same bag can hang for head-level work for a taller adult or drop for body shots and hooks. A 39 in hose handles filling and draining at a tap, and when the session is over the shell weighs 15.5 lbs empty and stores flat. It pairs easily with gloves, wraps and the rest of a home boxing setup, and it works wherever there is something to hang it from: a gym rack, a garage beam, an office corner during a lunch break or a covered patio. Complete accessories arrive in the box, so setup is a short job rather than a project.
