Vacuum insulation provides superior heat retention--your beverage stays hot or cold for hours.

A special manufacturing technique was used to make the body ultra-lightweight and compact.

Zojirushi flip-open lids are designed to release and hold, then flip open. This 2-step lid release allows condensation on the lid gasket to fall back into the mug instead of splattering.

Lid completely disassembles for easy and thorough cleaning.

Air vent on the mouthpiece allows beverages to flow out smoothly, without gushing or overflowing.

Safety lock prevents the lid from opening accidentally.

Nonstick coated interior makes cleaning easy.

All surfaces that come into contact with your beverage, including the lid and 18/8 stainless steel interior, are BPA-free.
