Leather is known to be one of the strongest and durable materials on Earth. So it was a no brainer when it came to our premium punching bags, we would use thick premium cowhide leather that would last through the toughest wear and tear. This is why our bags hang in professional boxing gyms across the country. We made sure that our Muay Thai Leather Punching Bag was strong enough to take years of abuse, from hard hitting punches to fast powerful kicks. The inside of these heavy bags features strong canvas lining for extra reinforcement to make sure they don’t rip or tear, and the stitching is triple reinforced throughout to ensure that your duct tape stays in the tool shed, where it belongs!
