Perfect size and keeps my coffee warm.

I love the Member's Mark Coffee Tumblers. I have the 12 oz size, and it holds just the right amount of coffee to start my day. I'm also impressed by how long it keeps my coffee warm. Since I usually drink one cup, it lasts for several hours and stays warm the whole time.
