That excellent heat retention is due to the Zojirushi’s vacuum-insulated, double-walled stainless steel. This Corkcicle tumbler keeps my coffee hot on my subway commute, and is secure enough to sneak a couple of sips while standing on a crowded, moving train. The Cole also has a cork accent, though on this mug, it’s a “built-in coaster,” which seems rather pointless since a well-insulated mug shouldn’t sweat. Cork Sleeve: A naturally renewable resource, this cork sleeve is responsibly manufactured from a sustainable source of cork.

I still found it worked a little too well, and found myself taking the lid off so I could drink from it sooner.While the body of the cup is vacuum insulated, the lid isn’t, to allow the coffee to cool to drinking temperature. Stanley Adventure Vacuum Quencher: It's not that it's a bad tumbler, but rather that I don't see the point. Miir says that the Climate+ uses no new plastic (the lid is 100 percent recycled and recyclable), and its insulation uses 25 percent less stainless steel than traditional insulated mugs.

If you've got mobility or pain issues that make tilting your head a hassle, this mug is a solid performer. If you leave it upside down for more than a few seconds or shake it, it’ll drip, but we couldn’t get it to leak by knocking it onto its side. Also, as with the Miir above, our testers’ noses got pressed into the piece that flips back while drinking—especially as we got toward the bottom of our hot and cold drinks. But it has Contigo’s Autoseal lid, and though the Transit mug’s push-button mechanism is slightly different from the lid on West Loop (and locks and unlocks by twisting the lid), it’s equally annoying to have to hold down a button as you drink. The cup has a sleek, black design with orange branding and is made from stainless steel, so it is super durable yet compact and perfect for carrying in a bag.So we looked for mugs that offered a range of sizes—including mugs big enough for those who do like to chug 24 ounces of coffee on the way to work. Miir makes one of my favorite stainless-steel water bottles, and its insulated travel tumbler doesn’t disappoint. The interior is ceramic-coated, so you don’t get any metallic flavors, and the thin metal lip is curved like a cabernet glass.
