We have finally located a bop bag that should last for years.  This bop bag was designed by an industrial designer and developed specifically for settings where toughness and durability matter.The exterior is covered with Marine vinyl, and the interior consists of a polystyrene center, surrounded with fiber fill. A heavy sand base keeps the bag upright. We think the size is perfect:20” base and 42" tall.
Check it out and let us know what you think. TUFF BOP BAG
