The Iron Flask 16 oz Classic Tumbler is the perfect insulated tumbler for your morning coffee, your evening glass of wine, and everything in between. This double-walled stainless steel tumbler keeps your beverages cold for 12 hours and hot for 3 hours without the funky metallic taste or breaking a sweat.
