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 20oz 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. STACK & STOW Bring two or 10, you're still packing efficiently. Remove the lid and nest your Rambler® 20oz Cups to save space. 18/8 STAINLESS STEEL Made with kitchen grade stainless steel, so they’re puncture and rust resistant. DOUBLE-WALL VACUUM INSULATION Keeps cold drinks cold and hot drinks hot until the last sip. DISHWASHER SAFE Because no one needs more work to do.
