The Rambler Half Gallon Jug (1893 ml) is built to take on the wild, whether that's rough tumbles from the truck cab or fishing the Texas flats in August. Like the rest of the Rambler series, it's constructed from 18/8 stainless steel, has double-wall vacuum insulation, and comes ready with our No Sweat? Design. But this Rambler Jug is also outfitted with our MagCap and dock, so your cap is never out of reach while you grab a drink. The one-inch of lid insulation locks in your drink's temperature unlike any other water jug out there. If you want to take your cold (or hot) drinks further for longer, the Rambler Half Gallon Jug has you covered.
