Heavy Bags have an important place in boxing gyms, as well as home gyms. They are a great tool for relieving stress while getting a great workout, and are used by millions of people for casual exercise and intense training. When we designed our punching bags, we kept both the casual user and professional fighter in mind. The Vinyl Muay Thai Heavy Bag is built to last, with triple reinforced stitching throughout, inner canvas lining to prevent rips and tears, and webbed stitching all over the suspension straps. These bags are built to last a very long time, and ready to take a beating from anybody who wants to put them to the test.
