It might seem weird to get excited about a cup, but this is no ordinary cup (just take a look at the reviews). Our 30 oz tumbler is the foundation of our drinkware collection with several different styles and customization options available. The tumbler's design has been engineered from the inside-out to ensure it's ready for any challenge you throw at it. Corrosion-resistant 18/8 stainless steel (a.k.a. 304 stainless steel for you fabricators out there) is cold worked for durability and vacuumed sealed for superior insulation. The inner wall is copper lined for more even temperature distribution within your beverage of choice.
