Product Description

Call us radical, but we at Iron Flask believe that hot drinks should be hot and cold drinks should be cold—and they should stay that way. The double-walled stainless steel 16 oz Rover Tumbler keeps your coffee and tea piping hot for 4 hours and your ice water fit for a polar bear for 18 hours, with no bottle sweat. And thanks to the Rover’s powder-coated finish, you never have to worry about your tumbler cup looking dinged up as the day goes on. We’ve included 2 straws for different sippin’ options.
