Muay Thai punching bag features a 6 ft tall apex 130 lbs. Made out of heavy-duty vinyl that we also use for custom 300 lbs bags. Ships in a reusable heavy-duty vinyl heavy bag cover. 300 lbs material capacity - meaning that you can add extra weight to the bag if you like, up to 300 lbs. Designed with heavy-duty straps that are made out of the same material as the punching bag, so you dont need any chains.
