E&S Serengeti Tumbler

Thanks to its double-wall vacuum insulation, this tumbler is designed to maintain your beverage's temperature for several hours. While exact times vary based on the ambient temperature and how often you open the lid, it is built to keep ice frozen or coffee hot throughout a typical workday.

The lid is engineered to be spill-proof, meaning it is designed to prevent leaks during normal movement and travel. However, like most tumbler lids, it is not 100% leak-proof if the cup is fully inverted or tossed loosely into a bag.

The 40 oz capacity is quite large, so while it fits many modern vehicle cup holders, it may be too wide for some smaller or older models. We recommend checking your vehicle's cup holder diameter if you plan to use this primarily for commuting.

The 3D design is integrated into the tumbler's finish to withstand daily handling and regular use. To keep the imagery looking sharp and detailed over time, we recommend hand-washing the tumbler rather than putting it in the dishwasher.

Yes, the tumbler is suitable for both hot and cold beverages. If you prefer to drink hot coffee or tea without the straw, you can simply remove it and sip directly from the lid opening.
