A travel coffee mug must do at least 2 things extremely well: keep your coffee hot, and keep it from spilling all over your bag/car/desk. Additionally, matters of size, aesthetics, ease of cleaning and one-handed operability may be factors to consider. Our list was assembled based on CNET's previous picks, those that have been well-vetted by other review sites and appear repeatedly on best lists, and best-selling and consistently highly-rated models at major retailers such as Amazon, Bed Bath & Beyond and Target.

Most travel coffee mugs claim to keep liquids "hot" for about 5-6 hours. To test this, I filled each of the models here with 170-degree liquid and measured the temperature after both 3 hours and 5 hours. Lids for travel mugs tend to fall in 1 of 2 camps, either some sort of threaded, screw-on mechanism or else a plastic and rubber twist/press-on lid that creates a vacuum seal. To test for leakproofness, I repeatedly upended each mug while full, looking for even a hint of a dribble.
