E&S Bulldog Tumbler

The double-wall stainless steel construction is designed to maintain your beverage's temperature for several hours. While exact times vary based on the ambient temperature and how often the lid is opened, it is built to keep coffee hot or water ice-cold throughout your workday.

The lid is engineered to be leak-proof, meaning it is designed to prevent spills and leaks during normal use and travel. However, we always recommend keeping the tumbler upright to ensure the best performance.

No, this tumbler is made of stainless steel and is not microwave safe. Putting it in the microwave could damage the vessel and your appliance.

The empty tumbler weighs 24 ounces. When filled to its 40-ounce capacity, the total weight will be approximately 4 pounds, depending on the density of your beverage.

The 3D design adds character and texture to the exterior, but it does not interfere with a standard grip. Because of the intricate detailing, we recommend hand-washing the exterior to preserve the design, though the stainless steel interior is straightforward to clean.
