QAD now offers a custom Yeti tumbler that’s built to last. The Rambler® 20 oz. Tumbler is a fan-favorite and is crafted from sturdy stainless steel with double-wall vacuum insulation that ensures your beverage’s temperature remains constant. The tumbler and MagSlider™ Lid are part of the Rambler® Drinkware Family, and both are dishwasher-safe for effortless cleaning. The included MagSlider™ Lid boasts a magnet that offers an extra layer of protection, preventing heat or cold from escaping, and keeping your drink inside. However, it’s important to note that this magnet component is not leakproof and cannot prevent spills.
