Any tumbler thats coming along for the ride needs to be tough enough to keep up. Our fan-favorite Rambler 591 ml Tumbler is made from durable stainless steel with double-wall vacuum insulation to protect the temp of your beverage at all costs. Like the entire Rambler Drinkware Family, the 591 ml Tumbler and MagSlider Lid are dishwasher-safe for easy cleaning. 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 notethis magnet component is not leakproof and will not prevent spills.

Magnets Makes for easy opening and closing.

Double-Wall Vacuum Insulation Keeps cold drinks cold and hot drinks hot until the last sip.

Dishwasher Safe Because no one needs more work to do.

18/8 Stainless Steel Made with kitchen-grade stainless steel, so theyre puncture and rust-resistant.
