Liquid doesn’t pour out too quickly (no scalded tongue or ice cubes in the face) and when tightly sealed, it doesn’t leak.

Grind One is built from stainless steel, and with airplane-style toggle switches and a sleek and minimal design - it's an antidote to the mass-market plastic machines that seem destined for landfill. The Brumate doesn’t retain heat nearly as well as the Zojirushi, but if you consume your coffee within an hour or two, it’s more than sufficient. Besides its bug-killing powers, the cup is comfortable to drink from and pretty good at keeping the liquid inside warm for over an hour. However, if you’re the kind of person who likes to drink copious amounts of coffee (or tea) throughout the day, I’d say the Thermos travel tumbler is ideal.Klean Kanteen is best known for its lightweight stainless steel reusable water bottles (and for tripping up our spell check every damn time) but the brand also makes a very nice double-wall, vacuum-insulated stainless steel travel tumbler. We have a range of mix-and-match colours available for you to style, along with 8oz and 12oz capacities. I used to pour water into a carafe and then into a glass at my desk, but after several tip overs I realized that something had to change!

Thanks to Senseo’s practical to-go cup, you have a stylish and convenient way to bring your coffee with you when you’re on the move. In addition to my commute on the subway, I've taken this little wonder on train rides to upstate New York, and I've never spilled a drop. Whenever I can foresee some serious abuse happening to a coffee mug on a trip, I take a Hydro Flask. But because it doesn’t have a leak-proof lid or fit into a car cup holder, it’s definitely more of a “coffee on the front porch” mug or “hot toddy around the campfire” mug than an actual commuting mug. Unfortunately, the way it’s designed makes it impossible to get the lid completely out of the way when drinking, which resulted in little spots of coffee on our testers’ noses with every single sip.

It keeps my caffeine cold, fits the extra-large ice cube I put into the bottom, and doesn’t leave rings on tables when I set it down. Like when you were younger and would stamp on a soft drink can to squash it, the Stojo cup collapses, with the cup’s body fitting into the lid. Many of us are guilty of grabbing a latte and, after an hour or two, quickly discarding that paper or plastic cup into the trash. The tumbler’s wide mouth (wide for Klean Kanteen, anyway) is big enough to fit most ice cubes, and the bottle itself is slender enough to fit most cup holders. A steel bottle, especially one with no liquid in it, should be able to survive that without battle scars.
