The Carbon Claw Impact GX-3 3ft synthetic leather punch bag is a great training tool which allows you to increase you hitting power and endurance, sharpen your technique and train in a safe environment where you can practise throwing punches correctly. The weighted resistance of the bag reduces the risk of injury and it also lets you improve your movement and hand-eye coordination by working around it. Filled with compressed cloth material, the bag is strong and durable to withstand what you can throw at it, and the seams are all double stitched to increase the safety and strength of the bag. The top cover has a heavy-duty zip and the 4 metal D-rings and 4 webbing straps used to hang it are very robust.
