JoyJolt Tumbler

Thanks to the triple-wall vacuum insulation and copper lining, this tumbler is designed to maintain temperatures for several hours. While exact times vary based on the starting temperature and how often you open the lid, it is more than capable of keeping coffee hot through a morning commute or a smoothie cold during a workday.

Yes, 12 ounces is equivalent to a 'tall' size at most major coffee chains. It is a perfect fit for a standard cup of coffee, a latte, or a smaller iced beverage, making it an ideal size for those who prefer a compact vessel over a bulky travel mug.

The integrated handle is designed to be ergonomic and compact, but whether it fits your specific cup holder depends on the vehicle's design. Because the handle is built into the side, it may protrude slightly more than a standard straight-walled tumbler, so it is best suited for cup holders with open sides or larger diameters.

The included lid is designed to prevent spills and splashes during normal use, such as walking or driving. However, it is not fully leak-proof, so you should avoid tossing it into a bag or backpack where it could tip over and leak.

While the stainless steel construction is durable, we recommend hand-washing the tumbler to preserve the integrity of the vacuum seal and the finish over time. Harsh dishwasher detergents and high heat can degrade the insulation properties and the exterior coating.
