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 YETI® Rambler® 30 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.
