You can be sure that the Iron Flask 24 oz Classic 2.0 Tumbler won’t break a sweat while keeping your drinks cold for 16 hours and hot for 4 hours, thanks to its double-walled vacuum-insulation. This tumbler cup is the perfect size to keep you hydrated while fitting in most cup holders. We’ve outdone the classic tumbler with this 2.0 version by making it leak-proof and adding a rubber bottom that doubles as a non-slip and noise-proof coaster. It includes two different insulated lids; a splash-proof straw lid with two straws, and a 100% leak-proof flip lid. No more unnecessary spills, you’re welcome!

• BUILT-IN COASTER: Classic 2.0 tumblers have a rubber bottom that makes them slip-proof, noise-proof and even more durable.
