This one's for all you coffee junkies with a long commute. Does your long drive to work make it impossible for you to enjoy a cup of coffee during a morning talk show? The solution to your problem is a good travel mug. If you're serious about your coffee, the best way to go would be a stainless steel travel mug. Plastic mugs are known to be fragile and, over time, can affect the taste of your coffee. Stainless steel mugs also provide better insulation. Just remember to keep the mug out of direct sunlight. Too much exposure to sun can warp the lid and compromise the mugs seal. You don't want to spill!
