Stanley Classic Vacuum Mug

The mug features a push-button lid that opens the drinking seal when pressed. Once you release the button, the mug automatically seals, making it easy to drink while commuting or multitasking.

Yes, the 12 oz capacity and slim profile are designed to fit most standard vehicle cup holders comfortably.

Yes, the vacuum-sealed lid is designed to be leak-proof when properly closed, allowing you to toss it into a bag without worrying about spills.

Thanks to the double-wall vacuum insulation, this mug is designed to keep beverages hot for several hours, though exact performance depends on your starting liquid temperature and how often you open the lid.

While the stainless steel body is durable, we recommend hand-washing the lid to ensure the internal seal and push-button mechanism remain in optimal condition over time.
