The most-important thing for me in a mug like this is that it keeps the coffee hot. I work in a role where I could be called away on a moment’s notice and have to leave my coffee behind for a couple of hours. In an ordinary mug, this means I’ll come back to find it room temperature. The Zojirushi will keep it hot for hours on end. I’ve filled it at 7am and had it still comfortably warm at 1pm the same day. My old stainless steel Thermos mug, which was almost as expensive, did well too.
The Zojirushi Stainless Steel 16oz. Mug has a vacuum insulation that keeps beverages hot or cold for hours. Easy-to-clean nonstick coated interior. Tight fitted flip-open lid keeps beverages hotter or colder than travel mugs. Safety lock to prevent the lid from opening accidentally. Lightweight design for added portability.
