Tervis knows insulated drinkware. The Heirloom 16oz Tumbler is a double-walled glass cup that handles hot coffee and iced tea with equal composure. The key feature here is the vacuum-insulated construction between two layers of glass. It keeps drinks hot for longer than a standard mug, and cold drinks stay chilled without leaving a puddle of condensation on your desk.

The glass is thick and break-resistant, which matters for everyday use. You can microwave it to reheat your coffee, toss it in the freezer to pre-chill for iced drinks, or run it through the dishwasher without worry. The Red Starburst pattern is printed between the walls, so it won’t fade or peel over time. At 16 ounces, it’s a solid middle ground—big enough for a full pour, small enough to hold comfortably.

One thing to note: the double-wall design means the exterior can feel warm to the touch with hot liquids, but it won’t burn your hand. The tumbler has no lid, so it’s best for home or office use rather than commuting. If you want a glass that works across temperatures without sweating or shattering easily, this is a straightforward pick.
