A water-filled punching aqua bag provides up to 110 lbs of resistance so you can practice strikes with a responsive target instead of a sand-filled bag. The 18-in diameter and 23-in height create a compact shape that swings and absorbs impact to help reduce stress on your waist and joints. Thickened PVC construction and metal hardware support repeated punches in home, office, or gym settings. A 39-in hanging chain and 39-in water hose with injector simplify mounting, filling, and emptying for storage.
