Unfortunately, you need to use two hands to open the leak-proof lid, which isn’t always conducive to drinking hot coffee while on the go. On the other hand, keeping track of all those parts (especially the support ring) can be kind of annoying. The West Loop mug with Contigo’s leak-proof Autoseal lid is very leak-proof, thanks to a lock switch on the top. Most often this mug has been my subway companion, though I have used it for road trips and early morning flights that require a caffeine boost before boarding.

The cup is pleasant to drink from and features a swivel stopper to close the mouthpiece and prevent leaks, but we wouldn’t risk putting it in our bags if it were full. While a tad gimmicky (it isn’t that hard to find the hole through which to drink on regular lids), it does make it more similar to a normal mug.The Brumate Nav, while not as great at retaining heat as the Zojirushi, has an equally-secure lid and the added benefit of being dishwasher-safe. Like all of Hydro Flask’s insulated products, this mug has great temperature retention and it’s also very durable thanks to solid construction.

There are dozens of reusable coffee cups available as brands try to help consumers be more environmentally conscious. Gorgeous little cup with the elephant on the front and so much better than drinking from a thick clumpy plastic cup, better to carry around than a glass one even with a plastic cover they still chip.

It is the essential source of information and ideas that make sense of a world in constant transformation.

I personally love that this mug doesn’t have a handle, because it’s so insulated it never burns my hands, yet the coffee inside stays piping hot, and its shape is nice and easy to hold. It’s narrow enough to fit any cupholder or backpack bottle holder, and it feels tough enough to survive years of abuse. Lukewarm coffee is a great way to get your whole day off to rough start, and nobody daydreams about relaxing by the pool with a tepid glass of 70-degree water by their side.Cork Sleeve: A naturally renewable resource, this cork sleeve is responsibly manufactured from a sustainable source of cork. But the angle of the new lid means our testers’ noses got smashed up against it every time we took a drink, and because of a lip around the inside of the body, it’s hard to get every last drop of coffee out of this mug.

Stainless steel is generally considered the best material for reusable coffee cups because it’s non-reactive, durable and excellent at temperature regulation. Plastic can be quite durable, but it’s never recycled, only down-cycled, meaning eventually it’ll reach a point where it’s no longer usable. The result is a robust, high-quality travel cup that is designed to last a decade and is 100 per cent recycled again at the end of its life.Like all the tumblers on this list, it’s vacuum-insulated to keep hot drinks hot and cold ones cold. The brand is known for its iconic insulated steel thermoses, which promise hours-long insulation for hot drinks and durability for wherever you’re taking your beverage— hiking, camping, thrown in the back of your car on a road trip, you name it. Yeti's most mug-shaped Rambler mug has the best size selection of all of the Rambler mugs and the two smaller sizes (10 ounces and 14 ounces) are stackable. It didn't keep our coffee hot nearly as long as the Zojirushi and though it has a leak-proof lid, it doesn't lock like the Brumate does. Like the Ello Campy (above), the Ello Cole is a budget-friendly, vacuum-insulated, stainless steel tumbler with a leak-proof sliding spout cover.
