The Iron Flask 16 oz Rover 2.0 Tumbler features the double-walled stainless steel design you love from the original Rover, keeping drinks cold for 18 hours and hot for 4 hours—but we’ve found a way to make the rover not only more indestructible, but quiet as a mouse. Our new rubber bottom acts as its own coaster, creating a slip-proof, clang-proof experience at your desk, in your car, or on your countertop. You’ll also find two leak-proof lids in your box: a flip lid and a straw lid with two straws so you can choose the way you sip on your fav drink.
