I will second this. I have been using this one for three years and love it. It fits in a bottle cage and doesn't leak. I have used it on motorcycle trips as well, putting it in a bag while it is filled with coffee. No leaks, and it stays hot for hours. I used it yesterday on a car trip. I filled it in addition to the combination french press/travel much I have, and didn't drink it until a little over six hours later, still hot.
