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 cup holder 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.
