The Rambler® is the line that gets you through the day. Your morning brew stays hot, and your iced coffee will stay cold - so take your time. Kitchen-grade stainless steel with double-wall vacuum insulation will protect your drink at all costs. The entire Rambler family is 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 note - this magnet component is not leakproof and will not prevent spills. Duracoat™ color finish.
