Zojirushi SM-SA36BA Tumbler

Zojirushi's vacuum insulation is highly effective, typically keeping beverages hot or cold for several hours. While exact performance depends on the starting temperature and how often you open the lid, it is designed to maintain drinkable temperatures throughout a standard workday.

Yes, the lid features a safety lock to prevent accidental opening. When the lock is engaged, the one-touch button cannot be depressed, making it safe to carry in a bag or backpack without worrying about leaks.

The non-stick coating is designed to be inert and food-safe, meaning it should not impart any metallic or chemical taste to your beverages. It also helps prevent stains and odors from lingering after you wash it.

The lid is designed to be disassembled, which allows you to reach all the nooks and crannies where residue can build up. We recommend taking it apart regularly to ensure a thorough clean, especially if you drink coffee or tea with milk.

With its compact, slim design, this 12.2-ounce model is built to fit comfortably in most standard car cup holders. Its sleek profile makes it a great choice for commuting.
