This versatile vessel pulls its weight around the fire, keeping coffee hot until the last sip and beers cold until the keg is tapped. The cupholder-friendly Rambler® 20 oz. Stackable Cup comes with the splash-resistant MagSlider™ Lid to protect your beverage while on the go. Like the entire Rambler® Family, it’s over-engineered to survive extreme adventures and double-wall vacuum insulated so your beer is ice cold or your coffee is hot from the first sip to the last. Please note: This magnet slider is not leakproof and will not prevent spills.
