The Iron Flask 20 oz Rover 2.0 Tumbler has all the powder-coated, temperature-controlled swagger of the original Rover, keeping your drinks chilled for 18 hours and cozy for 4 hours, but it’s now 100% leak-proof. Whether you use the flip lid or the straw lid (with two straws in case you lose one), you’ll feel confident knowing you’ll be drinking your beverage and not bathing in it. And with the all-new rubber bottom, this stainless steel tumbler is even more dent- and ding-resistant than its predecessor, as well as slip-proof and noise-proof.
