Driftless Studios Tumbler

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

At 30 ounces, this tumbler has a wider base than standard 16-ounce cups. It will fit in most modern, larger-sized vehicle cup holders, but it may be a tight fit or not compatible with some older or smaller console designs.

Yes, the exterior is designed to remain dry regardless of the temperature inside. This prevents condensation from forming on the outside of the cup, so you won't need a coaster or worry about water rings on your desk.

While the durable construction is built for daily use, we recommend hand washing to preserve the integrity of the insulation and the exterior finish over the long term. High-heat dishwasher cycles can sometimes degrade vacuum-sealed drinkware.

The lid is designed to be splash-resistant for everyday use, such as walking or driving. However, it is not fully leak-proof, so we recommend keeping the tumbler upright rather than tossing it into a bag.
