The classic to-go coffee cup has stood the test of time, keeping the liquid inside reasonably warm while fitting in nearly any available cup holder. Barbour channels this design with its Reusable Tartan Travel Mugs. Made from food-safe PLA, they have an all-over tartan print in a masculine olive with a blue silicone lid and sleeve or a more feminine pastel colorway. Both offer a capacity of 13.5 oz and arrive in a wrappable box.
