Introducing the NEW RotopaX 2 Gallon. Same capacity and dimensions as our original 2 Gallon without the complicated twisting bottom. For those that love the shape and size of the original, but also like saving some money, this is the pack for you. RotopaX are the only rotationally molded EPA and CARB compliant containers available for sale in the United States. This is thanks to a patented three layer Roto-Molding process, along with specialty formulated plastic barrier material to meet the governments new extremely low permeability requirements. Our water containers are rotationally molded and great for storing any potable liquids as well as being frozen for nice cold water all day long. However, the plastic compound is a food grade plastic so it is safe for drinking.
