With double-wall vacuum insulation and one-inch lid insulation, the YETI Rambler Half Gallon Water Jug is built to keep things ice-cold (or piping hot) for longer. It has the same durable 18/8 stainless steel construction as the rest of the Rambler® series, which makes it damn near indestructible, with a hefty stainless steel handle to make hauling your half-gallon water jug easy. It's also outfitted with the quick securing MagCap and dock, so you can keep your cap close at hand while you grab a swig. This Rambler Jug is glacier sized for long days at the worksite or a rough day at the lease, so pack up your drinks and hit the road. Your Rambler Jug is built for whatever comes its way.
