Construction: Double-wall, vacuum-insulated stainless steel (inner and outer shell), which is what actually keeps drinks hot or cold — not the plastic outer casing.
Capacity: 1000ml / 1 litre.
Insulation performance: Usually rated to keep drinks hot for around 8–24 hours and cold for up to 24 hours, depending on the exact model.
Lid/stopper: Often a twist-and-pour or push-button stopper so you can serve without fully unscrewing the cap.
Cup: The lid frequently doubles as a drinking cup.
Care: Usually hand-wash only (even if the body is listed as dishwasher-safe, the stopper/cap often isn’t).
Use case: Coffee, tea, soup, or cold water — good for commuting, hiking, office, or home use.
