A coffee tumbler, also known as a travel mug or thermal mug, is a portable container designed for carrying hot beverages like coffee or tea. It typically features insulation to help maintain the temperature of the liquid inside, keeping it hot for an extended period. Coffee tumblers come in various sizes, materials (such as stainless steel, plastic, or ceramic), and designs. Some tumblers have additional features like spill-proof lids, handles, or built-in strainers for tea leaves. They're popular among commuters, travelers, and anyone who enjoys hot beverages on the go. Using a coffee tumbler is not only convenient but also helps reduce waste associated with disposable cups.
