Best Travel Mugs and Tumblers

The Autoseal lid is the reason this mug has been the default recommendation for a decade. Every other design here is open until you close it; this one is closed until you press a button, and it re-seals the instant you let go. In a bag being carried at an angle, or in a car going round a corner, that is the difference between an inconvenience and a laptop.

One-handed operation is the practical consequence. There is nothing to flip, twist or unscrew — a thumb on the button while the mug is already at your mouth. For anyone drinking coffee while driving or walking, no other mechanism here is close. The lock switch handles the remaining risk, which is the button being depressed by something in a bag.

Where it gives ground is heat and cleaning. It holds coffee hot for a solid few hours, which covers a commute comfortably, but it is not the six-hour performance of the Zojirushi. And the Autoseal mechanism is intricate: more small parts, more crevices, and a small drinking aperture that traps residue. It does dismantle for cleaning — the current design fixed the complaint that dogged the older sealed lids — but it needs doing regularly and thoroughly. Painted versions also chip where they rub in a cup holder, which is cosmetic but universal.

This is the same mug as the top pick in a smaller body, and for a great many people it is the more sensible purchase. A 16 oz travel mug holds a lot of coffee, and coffee that sits for two hours while you work through it ends up drunk lukewarm from the bottom half regardless of how good the insulation is.

At 12 oz it matches the size of drink most people actually make — a [milk drink from an espresso machine](/best-espresso-machines-under-500), or a strong filter coffee — which means it gets finished while it is still good. The slim body is the other advantage: it fits into bag pockets and narrow cup holders that a wider mug will not, and it is light enough to carry all day.

The physics are the one honest caveat. A smaller volume of liquid has more surface area relative to its mass, so it cools faster than the 16 oz version even with identical vacuum construction — still hours rather than minutes, but not the same figure. Everything else carries over unchanged, including the narrow opening that needs a bottle brush, the removable gasket, and the hand-wash-only instruction. It also costs nearly as much as the larger one, which makes the choice purely about the size of drink you want rather than the money.

This is a different product to everything else on this page and it belongs here because it answers a question the others cannot. A travel mug carries one drink. This carries a whole brew — the output of a [drip machine](/best-drip-coffee-makers) or a large [French press](/best-french-presses) — and keeps it hot for the better part of a day.

The volume does much of that work. A large mass of liquid loses heat far more slowly than a small one, so the combination of serious vacuum insulation and a couple of litres of coffee produces retention figures that no single-cup mug can approach regardless of construction. The lid unscrewing into a cup is not a gimmick; it is why the design has survived a century essentially unchanged.

It is also the easiest thing here to clean, which is worth saying because the mugs are not. The mouth is wide enough for a hand and a sponge, with none of the crevice-hunting a sealing lid mechanism demands. What you give up is everything about portability: it is heavy empty, it will not fit a cup holder, and drinking from it means stopping, unscrewing and pouring with two hands. Buy it for a car, a work site or a walk, not for a desk. The stopper is the part that wears out, and replacements are available.

This is the West Loop scaled up, and everything good about the 16 oz version applies: the Autoseal button, one-handed drinking, the lock switch, the lid that comes apart. The question is only whether you want this much coffee in one vessel.

For a long drive, the case is straightforward. 24 oz is most of a morning, the larger thermal mass keeps it hot for longer than the smaller mug manages, and it still drops into a standard cup holder. If the alternative is stopping to refill, this is the mug.

For most other uses it is more than is useful. It is tall enough to foul the spouts on a good many machines, particularly [pod brewers](/best-pod-and-capsule-machines) with fixed drip trays, which means filling it from a jug instead. Full, it is top-heavy and tips more easily than the squatter mugs here. And 24 oz is a lot of coffee to work through — the last third is usually drunk lukewarm no matter how good the insulation is, which is the argument for a smaller mug you refill rather than a large one you nurse. Buy on how much you actually drink in one sitting, not on the number.
