We recently got this ultra-minimalist travel mug for our coffee. The form factor and style of the container can’t get much simpler than this. It’s an excellent example of considered industrial design and aesthetics. The mug is called the “Carter” and it’s made by a company called Fellow. We got one of their water kettles as a Christmas gift last year, and it’s the best kettle we’ve ever had, ideally designed for making slow pour-over coffees.
