The Rambler 20 oz. Tumbler is built for durability with rugged 18/8 stainless steel that's both puncture- and rust-resistant. Engineered with double-wall vacuum insulation, it keeps cold drinks cold and hot drinks hot to the very last sip. Designed for convenience, it's dishwasher-safe and fits most standard cupholders. The included MagSlider™ Lid features a magnetic closure that adds an extra layer of splash resistance, helping to maintain temperature and contain spills-though it's not completely leakproof. Rugged, reliable, and ready for anything.
