Never let your favorite beverage lose its frosty (or piping hot) goodness before you have a chance to fully enjoy it with the YETI Vacuum-Insulated Rambler Tumbler. The Rambler Tumbler is over-engineered with kitchen-grade 18/8 stainless steel construction, meaning it's a tough, hard-wearing personal drink cooler that won't rust or leave a metallic taste. Double-wall vacuum insulation maintains ice twice as long as plastic tumblers - and it works just as well for hot beverages. The included lid keeps your liquid in its place and is easy to clean. It's also shatterproof and crystal clear, letting you know exactly how much of your drink you still have to look forward to. Capacity: 30 oz.
