I'm a HUGE coffee drinker. I use the Flip-and-Go Stainless Mug mostly for coffee, even though it works just as great with cold drinks. It will keep your drink hot/ cold for over 12 hours. The vacuum seal technology on the lid is out of this world. It seals it and prevents any leaking. The handle is easy to carry and flips with no effort needed. This is my absolute favorite travel mug.
