Consider the mug's material and construction for optimal performance. Stainless steel models with 2-ply insulation (also constructed of stainless steel) boast longer heating and cooling times. Although plastic mugs are less expensive, they're also less durable and may absorb the essence of hot drinks, altering the flavor of future beverages.
Select a size that holds the amount you typically drink and that sits in your car's drink holder snugly.
Find a mug with a screw-top lid, since snap tops can pop open if not secured properly. Insist on a drink flap that you can open and close easily with one hand (and without looking) for convenience and driving safety.
Decide on a model with or without a handle. Although a handle allows you to carry your drink securely when you're juggling multiple items, it may also prevent the mug from fitting into your car's drink caddy.
Pick a color that you love or that stands apart from the other travel mugs sitting in the sink of your company's break room.
