Zojirushi Tumbler

Thanks to the vacuum-insulated stainless steel construction, this tumbler is designed to keep iced beverages chilled for several hours. While exact times vary based on the ambient temperature and the amount of ice used, it is built specifically for all-day temperature retention.

The lid is splash-resistant, not leak-proof. It is designed to prevent spills while you are walking or working at your desk, but it should not be tossed into a bag or turned upside down.

Yes, the lid features a dedicated opening designed to hold the included straw snugly in place. This helps keep the straw upright and prevents it from sliding around while you sip.

While the stainless steel body is durable, we recommend hand-washing the tumbler and lid to preserve the finish and the integrity of the vacuum seal over time. Harsh detergents and high heat in a dishwasher can degrade the materials.

Because of its large 30-ounce capacity, this tumbler has a wider base than standard travel mugs. We recommend measuring your vehicle's cup holder diameter to ensure a proper fit before purchasing.
