Made from high-quality, rust-resistant 18/8 stainless steel, the YETI Rambler One Gallon Jug holds enough liquid to keep you hydrated anytime, anywhere. The double-wall vacuum insulation and insulated one-inch FatLid keep things ice cold or piping hot until the last pour or sip. The jug is also built with a hefty stainless steel handle which makes it easy to lug around.
