An insulated tumbler is a type of drinkware designed to maintain the temperature of your beverages—keeping hot drinks hot and cold drinks cold for extended periods. These tumblers are typically made from stainless steel with double-wall vacuum insulation, which prevents heat transfer between the inside and outside of the cup.
