As a freelance word-slinger, I am what you might call a VORACIOUS consumer of coffee. I make it in a French press, take it black, and drink it throughout the workday. There’s (almost) nothing I hate more than cold coffee, except an empty coffee mug, which is why I reluctantly agreed to let my wife buy us a $30 ish dollar insulated coffee canteen thingy. Initially, that seemed like a lot to pay for a metal travel mug, but when I experienced the magical heat-containing powers of the Klean Kanteen Insulated Coffee Mug in action, I realized this was no ordinary travel mug. This, my friends, is a mug powered by sheer demon magic.
