9 Best Travel Coffee Mugs (2024): Insulated, Steel, Thermal | WIRED

Staying hydrated can be a battle, especially if you're toting around a bottle of lukewarm water, coffee, or tea. Whether you drink cold drinks or hot ones, a vacuum-insulated beverage holder can keep it at your preferred temperature so that every sip is a joy. There are tons of vacuum-insulated bottles, mugs, and tumblers on the market these days. Most of them are perfectly capable at keeping beverages colder or warmer than room temperature for much longer than a non-insulated bottle, too.

I tested each bottle with both ice water and cold water, sat outside on a patio in indirect sunlight, and then with hot coffee left indoors, where the ambient temperature was 70 degrees. During testing so far, none of the bottles failed to roughly match up to their claims of how long they'd keep cold liquids cold and hot liquids hot. It's rare to run across an insulated bottle that's a total failure at doing that these days, but it's also rare to find one that truly stands out. Rather, I've noticed the features that tend to make or break a bottle are their leak-proofing, exterior coating, and cap. Here are the best travel mugs that impressed us, and some of the rest.

Note that my colleague, Medea Giordano, wrote a piece about the use of lead soldering in the construction of some reusable bottles.

Updated March 2024: We've added the Yeti Rambler Vacuum Bottle With Chug Cap, Stanley IceFlow Straw Tumbler, REI Co-op Camp Mug, and GSI Outdoors MicroLite 500 Flip. We've also added information about the use of lead in some bottles' manufacturing, as well as updated pricing and availability throughout.

Hydro Flask’s powder coating is one of the toughest I have come across on a beverage container. Whenever I can foresee some serious abuse happening to a coffee mug on a trip, I take a Hydro Flask. I’ve yet to dent or scratch one through routine carelessness over the past four years. Without a cupholder in my car, my Hydro Flask lived on the floorboards, rolling and crashing around with every maneuver, and it still held up. The pebbled texture is grippy, so you're less likely to fumble it if your hands get wet or greasy.

Narrow openings are fine for water, in my opinion, but for hot beverages, I like having a wider gap so I can take a big gulp. I'm less likely to burn my mouth on hot drinks when I can let them cool off through a bigger opening, too. The TKWide’s Cafe Cap is more like drinking from a regular to-go coffee cup, rather than a water bottle.

All the colors have matte powder-coated finishes, which are more scratch-resistant than the brand’s smooth powder-coated finishes. That said, I haven’t found them to be as tough as Hydro Flask’s powder coating, and the uncoated stainless-steel ring on the bottom of the mug is pretty easy to scuff up.

The Brew Cork is greater than the sum of its parts. This double-walled, insulated mug is meant to replicate and replace paper coffee shop cups. It’s fun to drink out of. Many other tumblers’ lid openings are blocky or mash your nose, but the KeepCup is ergonomically on point. It’s not the best for road trips, nor the best for keeping a ton of coffee hot for hours, but I highly recommend the LongPlay if all you want is a reusable cup to cut down on single-use waste and keep your drink warm long enough for you to actually drink it. That said, the lid is a bit dribbly. While the interior and lip are glass—no metallic off-tastes here—the exterior shell below the rubber grip is plastic.

It doesn't fit a typical car’s cup holder, but if you like an insulated mug that resembles a cup more than a bottle or beer glass, the Climate+ is for you. It has the solid build quality and tough powder-coated finish we’ve come to expect from Miir, in a package that has less of an impact on the environment. 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. It’s also completely BPA-free.

This camp cup is awfully charming, harkening back to the classic blue, enameled camp cups that ooze 20th-century Americana. Like all the tumblers on this list, it’s vacuum-insulated to keep hot drinks hot and cold ones cold. Its screw-on plastic lid, with a sliding lever for sipping, is leak-proof enough. If you leave it upside down for more than a few seconds or shake it, it’ll drip, but I couldn’t get it to leak by knocking it onto its side. The handle is plastic to avoid conducting heat from hot contents, and the inner part of the handle is lined in cork. The Campy isn’t enameled—it’s just painted to look like it—but it pulls off the effect well.

Instead of a tiny sippy hole, the Carter’s screw-on cap reveals a wide tumbler that lets you breathe in your coffee’s aromas as you drink. The opening is 69 millimeters wide, so you can use most manual coffee brewers, such as an AeroPress or Hario pour-over, directly on it. That’s too wide for many cars’ cup holders, but it’s plenty stable, and you won’t have to worry about tipping it over on a desk. My average-size hands had no issues, but some buyers with smaller hands might find it difficult or uncomfortable to hold.

The interior is ceramic-coated, so you don’t get any metallic flavors, and the thin metal lip is curved like a cabernet glass. Its textured matte exterior coating is tough and held up as well as the mighty Hydro Flask’s coating. It's been completely leak-proof too. You should have no concerns throwing it into your laptop bag completely full.

When traveling, I want to pack light. Snow Peak’s gorgeous insulated titanium camp mug is less than 4 inches tall, weighs only 4.2 ounces, and has foldaway handles to make it even smaller. Its 450-ml capacity equates to slightly more than 15 fluid ounces. As someone who finds washing mugs to be an interminable hassle, this is the easiest one to travel with—just refill, rinse, and carabiner it to the outside of your bag. I've carried mine up glaciated mountains and down desert trails for six years now, and although the lettering has worn away, the mug itself works as well as it did when new. You can also buy a Snow Peak lid for $14 separately, which is splash-proof and kept my coffee warmer for longer.

Tumblers and travel mugs are generally designed for you to pour your chosen beverage into, but what if you just want to put a can in there? These kinds of insulated drink holders are particularly useful when I'm out and about, drinking a canned soda or beer, and want it to stay cool in the summer heat.

Not only can you put the can directly into the drink holder, but you can also pour it into the Hydro Flask and drink directly out of it, if you wish. Just remove the collar, and now you've got a handsome, stainless steel rim to sip from. The collar fits over the bottom of the can to stabilize it too, so you won't lose it. This is the 12-fluid-ounce version that fits a standard beer, soda, juice, or wine can. There's also a 16-fluid-ounce Tallboy Cooler Cup for $28 if you're feeling particularly thirsty.

We've run through many travel mugs, and not all of them are winners. These are a few we like, just not as much as the ones above.

Miir Flip Traveler for $28: The Miir has a tough powder coating with a flip-top lid that is absolutely leak-proof. I couldn’t get one drop of liquid to escape, no matter what I did to this tumbler. It’s narrow enough to fit any cup holder or backpack bottle holder, and it feels tough enough to survive years of abuse. Personally, I also find it quite aesthetically attractive, with its sharp lines and angular cap, compared to its competition. Miir has stated that some of its bottles use lead, and its website states: “MiiR drinkware is frequently tested at a 3rd party accredited lab by COE Resolution CM/RES(2013)9. When MiiR drinkware is tested, lead is not detected. The limit of detection is < 0.002 mg/kg (ppm).” Representatives at Miir declined to clarify if the Flip Traveler is one of its bottles that use lead.

Yeti Rambler Bottle With Chug Cap for $50: The star of this bottle is what Yeti calls the chug cap, a threaded spout that's between a wide-mouth opening and a more typical sipping hole in size. I enjoyed it quite a lot. When gulping water, it flowed more smoothly and quickly than a sipping hole, but it didn't spill over my face, as a wide-mouth opening can sometimes do when in a hurry. A cap with a plastic handle screws on over it to close up the bottle. The handle is wide and robust. I'd use a carabiner to clip it to a backpack often and never worried about it breaking (36 fluid ounces of water is heavy). If you're a frequent sipper like me, you'll appreciate that it only takes a half turn of the cap to expose the chug cap. Yeti cautions that the chug cap (which can be unscrewed and removed) is unsuitable for hot beverages. Just to make sure I didn't burn my mouth on that initial, exploratory sip of hot coffee, I'd take it off when drinking something hot, which negated some of the bottle's convenience. Like most Yeti bottles, the exterior coating was durable and didn't scratch or dent during testing. Yeti uses lead in its manufacturing.

Stanley IceFlow Tumbler for $30: Rather than a long straw, the IceFlow has a stubby, flip-open straw about an inch long that's built into the cap. It was easy to manipulate with my thumb to flip it out, which I appreciated when I was hot and sweaty after a workout and didn't want to fumble with a hard-to-use cap. Its small diameter meant that I couldn't gulp water, though, only sip a steady trickle. The carry handle was big enough to use while wearing puffy gloves this past winter, and it flips down and out of the way when you don't need it. Both are a very nice touch that outshine most other bottles' handles. Like Stanley's other bottles, its exterior coating is tough enough that I noticed no scratches or wear. Stanley uses lead in its manufacturing process.

Contigo Luxe Autoseal for $36: What makes the Contigo “automatic” is a button on the side of the lid that opens the sipping hole. There’s a lock to prevent the button from opening the hole, too. With or without the lock activated, the Contigo never leaked a single drop. Some buyers have complained that the metal lid gets too hot, but I filled up the Luxe Autoseal with scorching, molten coffee, and the lid barely even got lukewarm. Contigo is also among the manufacturers that uses a lead solder bead in its construction. When reached for comment, a company representative said, “The bead is covered and insulated by multiple layers—it never comes in contact with users or liquids in the bottle—and cannot be accessed unless the bottle is fully deconstructed. No traces of lead are found on or in the bottle that would be exposed to the consumer or the beverages in the bottle.”

KeepCup Thermal for $26: This is the answer to those who like the KeepCup LongPlay's ergonomic shape and paper-cup-imitating feel but long for a cup that can keep their coffee warmer for longer. The Thermal is, like most of the vessels in this guide, vacuum-insulated stainless steel that insulates against heat loss or, in the case of cold beverages, heat gain. It shares the Brew Cork's slightly dribbly lid, although it loses some of the novelty of the Brew Cork's glass.

REI Co-op Camp Mug for $23: There are getting to be an awful lot of insulated camp mugs in this basic style on the market, and REI's own is a perfectly fine option that doesn't particularly stand out. REI didn't attempt any gimmicks with its lid, which is a durable piece of thick plastic with an open hole for sipping and a smaller hole for airflow (so that sipping is smooth). You can't just toss it in a backpack or on the floor of your car without it leaking, but for a camp mug, that's fine. They're better suited for use in camp, a motorhome, or on a desk anyway, in my opinion. The exterior coating was tough enough to show no scratches, even after knocking it over a few times outside, and the REI graphics were tasteful and attractive, in my opinion.

Miir Camp Cup for $28: Miir's insulated coffee mug doesn't leak, it insulates hot and cold drinks just fine, and the coating is as tough as any Miir. But it's up against tough competition, and for the same money the Hydro Flask Mug is a bit nicer. The Miir lacks the Hydro Flask's stainless steel rim, and the transparent plastic lid feels a little cheap. The sliding opening on the lid felt like just an extra step to operate each time I wanted a sip.

Hydro Flask All Around Travel Tumbler for $35: The rounded handle is comfortable to hold, which is important in an 18.4-ounce mug loaded with up to 32 fluid ounces of drink. Like most Hydro Flask products, it comes with the same bomb-proof powder coating (in optional soft, pastel colors) that resists scratches and chips very well, plus the addition of a straw poking through its lid. There's also a 40-fluid-ounce version for $40.

GSI Outdoors Glacier 15-Fluid-Ounce Camp Cup for $20: It's not too easy to find at retailers, and when you do, they tend to be available in just a few colors and go in and out of stock. This cup is awfully simple, particularly the incredibly basic lid, but it's more than a little endearing. There's a brushed stainless steel version and, my favorite, a "blue speckle" that imitates the classic enameled blue camp cups of past generations, although both of these colors are plain steel. Other colors come in a more durable-seeming pebbled coating.

Zojirushi Stainless Steel Mug for $29: The stainless-steel interior is BPA-free and has a wide-mouth opening. The lid locks to avoid accidental spillage, and I once accidentally left hot tea in it for 18 hours and found it still hot when I opened it again. It’s also small enough to fit in my jacket pocket on chilly morning walks. It’s not my preferred mug for daily use, simply because the lid has three separate parts—a mouthpiece, a gasket, and a lid—that are deeply ridged and hard to clean.

Rambler Stackable Cup for $30: This insulated cup holds 16 fluid ounces, which is the capacity of a typical tall drinking glass. The best aspect of this is that you can stack several of them, so you can keep a bunch in your pantry without taking up much room. It comes with Yeti's durable powder coating, too, making them among the toughest options out there.

Hydro Flask Mug for $28: The Hydro Flask Mug merges a durable powder-coated, vacuum-insulated construction with the traditional, handle-sporting shape of a diner or camp mug. Hydro Flask does it better than most. The stainless steel rim makes it nicer to sip from than competitors' mugs, and it comes with Hydro Flask's usual drip-proof lid and bomber-tough powder coating that is nearly impossible to scratch. But it is more at home on a desk than at a campsite or in a car's cup holder, which it can't fit into.

GSI Outdoors MicroLite 500 Flip for $30: Under the button-activated, flip-up lid there's a contoured bowl that you drink from, as if somebody cut the top half off a plastic cup. It felt gimmicky and unnecessary. It didn't do anything that just drinking from an open bottle couldn't do, and it tended to collect stray water droplets after I was done drinking. The overly complex cap was harder to hand wash than most caps, although the dishwasher could clean the cap without issue. What saves the MicroLite 500 is the stainless steel rim, which felt nice to drink from when the cap was removed, plus the array of available colors in durable, non-scratch coatings. Minus the cap, the bottle was fairly nice, if not particularly a standout among the competition. There's a MicroLite 500 With Twist Lid for $30 that does away with the gimmicky cap and has a simpler lid, although the carry strap is narrow and not as robust as I'd have liked.

Owala FreeSip for $28: Product reviewer Medea Giordano loved the FreeSip (9/10, WIRED Recommends) for its dual drink spouts: one open hole, plus a built-in straw. If you've got mobility or pain issues that make tilting your head a hassle, this mug is a solid performer. It's easy to grip too, with its flattened sides, which can come in handy for those with reduced hand dexterity.

OtterBox Elevation for $30: At 8.5 inches tall, the Elevation 20 looks a lot bigger than it is. It has a copper lining that the company says helps better maintain your beverage’s perfect temperature, although I saw no noticeable difference in the Elevation's temperature-holding abilities. The clear press-on lid has a locking mechanism that you can switch it out for a straw lid or a French press lid if you’re in a hurry. It comes in a variety of stunning hues. OfferBox uses lead in its construction. When reached for comment, a company representative said, “ The seal is not open or accessible to the end user, and at no time, under intended use, could it come into contact with the end user. The OtterBox Elevation tumbler meets all applicable US regulatory requirements.”

Purist Mover for $48: Ever empty a stainless-steel bottle of one beverage and fill it up with a different one, only to notice that the taste of the first drink lingers? The Purist has applied a thin layer of glass over the interior of the Mover, which keeps this taste transfer from happening. You can down a mug full of coffee and then fill it with herbal tea without risking a coffee aftertaste. I didn’t experience leaks from the Element top, but a high number of customers have reported their Purist lids leaking over time. I’ll keep using the Purist and update this page with information on how it performs.

S'well Traveler Tumbler for $30: S’well boasts that its tumblers are triple-walled, but I'm not convinced that has much real-world benefit over a normal double-walled tumbler. It didn't keep beverages remarkably colder or hotter than its competitors, for example. What really sets the S’well apart are its designs. There are 12 finishes, from plain colors and bare stainless steel to elaborate patterns, such as blue marble and faux wood, and a slide-open lid so you don’t have to pop it off every time you want a swig of coffee.

Stanley Classic Vacuum Pint for $26: Stanley’s vacuum pint includes a press-on lid with a deeply pebbled exterior that’s reminiscent of classic flasks. Although it’s billed as a 16-ounce pint, Stanley has added a few extra ounces to accommodate foam (or splashing hot coffee), and the lid comes with a slide-in metal bottle opener if you like to go immediately from work to happy hour. Stanley uses lead in its manufacturing process.

We’ve tested a great many tumblers, and not all are winners. These aren't anywhere near as good as our picks above.

Greens Steel Beast 20-Ounce Insulated Tumbler for $18: Greens Steel’s Beast tumbler has more than 67,000 positive reviews on Amazon and is, at least for me, one of the top hits when I search Amazon for an insulated tumbler. But the rubber seal around the lid is thin and easily comes out of place. I was ready to write the Beast off when it was leaking like a sieve, but after I adjusted the seal, it was reasonably leak-proof. Sometimes it dribbles, sometimes it doesn’t, depending on whether the seal stays put when you’re attaching the lid. The exterior color coating is not as durable as the Klean, Hydro Flask, Yeti, or Fellow. It did come with a regular metal straw, a thick metal milkshake straw, and a cleaner brush.

Snow Peak Kanpai 500-ml Bottle for $98: Unlike most of Snow Peak’s line of camping and backpacking gear, the Kanpai is stainless steel, not titanium, and it’s not made in Japan. It’s a double-walled, insulated stainless-steel tumbler with a glossy finish, and it comes with three lids, for some unnecessary reason. There’s a white screw-on lid that needs to be removed every time you want a drink, and a black version of the same lid. The third lid—one with a sipping hole that can be closed with a sliding latch—leaks if the Kanpai tips over. It took damage in a mere 3-foot drop when it was empty, landing on its rim, which flattened. A steel bottle, especially one with no liquid in it, should be able to survive that without battle scars.

Toaks Titanium Double Wall 450ML Cup for $40: More often than not, I champion Toaks gear as an affordable source of titanium camp cookware compared to Snow Peak and Evernew and MSR, which tend to be more expensive. But this mug is only $10 less than the Snow Peak mug we recommend above, and its finishing is rougher.
