Zojirushi Mug

Yes. The flip-open lid is designed specifically for one-handed use, allowing you to pop the top and take a sip without needing to set down your bag or steer with one hand.

The safety lock is highly effective at preventing the lid from accidentally popping open. When engaged, it keeps the seal secure, making it safe to toss into a backpack or briefcase without worrying about spills.

The vacuum insulation is rated to keep beverages hot or cold for up to six hours. While external temperatures can affect this slightly, you can expect your drink to remain at a satisfying temperature throughout a standard morning commute.

The SlickSteel interior is designed to resist stains and corrosion, which helps prevent lingering odors or metallic aftertastes. Because the stopper is fully removable, you can easily reach all the nooks and crannies for a thorough wash.

To preserve the vacuum seal and the finish, we recommend hand washing this mug. The removable stopper makes the process straightforward, but putting it in the dishwasher can compromise the insulation performance over time.
