The Iron Flask 32 oz Rover 2.0 Tumbler brings everything you love from the original Rover and adds a 100% leak-proof design with both the flip lid and straw lid included, plus a rubber bottom for extra protection (and less noise). Every Iron Flask tumbler cup is vacuum-insulated between two walls of the highest-quality stainless steel, giving you durability, reusability, and temp control you couldn’t dream of with a plastic tumbler cup. That is, 20 hours of coldness or 5 hours of hotness for your drink of choice. Bonus: We included two straws because we know stuff happens.
