Any tumbler that's coming along for the ride needs to be tough enough to keep up. Our Rambler® 20 oz. is made from durable stainless steel with double-wall vacuum insulation to protect your hot or cold beverage at all costs. While the magnet on the included MagSlider™ Lid adds an additional barrier of protection for keeping drinks contained and preventing heat or cold from escaping, please note - this magnet component is not leakproof and will not prevent spills. Available in stainless and DuraCoat™ colors.
18/8 STAINLESS STEEL Made with kitchen-grade stainless steel, so they’re puncture- and rust-resistant.
DOUBLE-WALL VACUUM INSULATION Keeps cold drinks cold and hot drinks hot until the last sip
