It keeps my coffee HOT and doesn't leak. It displays the Thinking Atheist logo on one side, and the words start thinking. on the other side. Fits in my cars cup holder, and can be held by the handle, or just grip the cup by its side. The contents may be hot, but the cup is not. This is an excellent mug.
