Thermos Icon Tumbler

Thanks to its vacuum insulation, this tumbler is designed to maintain temperatures for extended periods. While exact times depend on the starting temperature of your beverage and how often you open the lid, it is built to keep coffee hot or water ice-cold throughout your typical workday.

The slide-lock lid is designed to be leak-resistant, which is great for preventing splashes and spills during daily use. However, it is not fully leakproof, so it is best to keep the tumbler upright rather than tossing it loosely into a bag.

With a base diameter of 3.5 inches, the Icon Tumbler is engineered to fit most standard vehicle cup holders. It is a safe bet for most modern cars, but if you have an unusually small or non-standard cup holder, it is worth a quick measurement first.

You can safely put the entire tumbler, including the lid, in the dishwasher. The stainless steel construction is durable enough to withstand dishwasher cycles without compromising the vacuum seal or the finish.

Yes, the lid is specifically designed to accommodate a straw. You can easily slide the lock open to insert your straw while still maintaining some protection against splashes.
