More than two feet longer than the original Century Vinyl Heavy Bag, this 72-inch long bag (88.5" when including straps) has a 42.5-inch circumference for more striking options, including high and low kicks. The Muay Thai Heavy Bag is composed of a durable vinyl shell with impact fiber filling. Ideal for Muay Thai and MMA training, this bag hangs from heavy-duty chains attached to web straps.
