Tested: The Best Travel Mugs For Hot & Cold Drinks On The Go

There are a lot of travel mugs and commuter cups that claim to be “thermal,” but most of them are just cheap imitators that can’t keep a cup of coffee at the ideal temperature that the true drinker demands. Don’t get ripped off by any second-rate piece of plastic with a styrofoam insulator that claims it will keep your hot beverages hot and your cold beverages cool for long drives and long days at the office. Go with one of our picks from our guide to the best travel mugs, which we’ve tested and reviewed so you don’t have to.

How We Tested

Let’s be honest: There are a LOT of travel mug options out there, with new ones making their way into the space each year. With that, we had to distill that list down to a select few. To do so, we used our years’ worth of expertise and experience using these vessels to help us out. We also looked at who were the major players in the game, the feisty newcomers, and the trendy outliers. From there, we came up with a short list, looking at materials, aesthetics, claimed performance (prior to testing), features, and lid function, and sourced samples for testing.

Testing took several days and consisted of actually using these mugs for both hot and cold beverages, depending on their intended purposes. For starters, we filled up each mug halfway with ice and halfway with water. Then we checked the temperatures initially and came back to them 15 hours later to see how much the temperature rose (or dropped in one instance). We only did this for the mugs that were intended for all-day drinking and cold temperature retention. In other words, the few mugs that were specifically for hot water only got tested for hot water. However, we performed the hot water test for all 8 mugs. In a similar way to the cold water test, we checked the temperature at the start and revisited each mug after 6 hours (mugs can’t hold hot water for as long as cold). Another thing we did after filling each mug was turn it upside down and shake it somewhat vigorously to see how much water, if any, leaked out. While almost all of these claim to be spill-proof when sealed properly, not all of them are leak-proof. So we’ve presented our findings as a distinction between the two terms. All of our results and findings are detailed down below.

What Makes A Good Travel Mug?

Travel mugs are generally best for coffee, tea, or any other hot (or cold) beverage you need on the go, making them ideal for commuting, traveling, and camping. It’s a better choice than disposable options from an environmental standpoint, but also from a health standpoint because you decide what’s going in there.

Size: 12oz to 24oz is the average range for most travel mugs (with 8oz – 12oz options available for smaller beverages like cappuccinos) and should be sufficient unless you can’t make frequent drink trips or consume entire pots of coffee. For those of you who do need more volume, there are options that get into the 32oz or 40oz territory.

Lid: Lids can vary slightly (and not so slightly) from mug to mug; they can twist open, flip open, snap shut, and even include a straw sometimes. Commuters might want something with a sturdy no-nonsense lid, and those who WFH may go for something with a flip top or a straw. Decide which lid works best with your lifestyle and feels best, and go for that one.

Material: Firstly, make sure whatever you buy is BPA-free, then decide if you want a tempered glass, plastic, or stainless steel mug. Stainless steel retains temperatures better, but glass is more sustainable and can be put in the dishwasher. Plastic is probably the worst of these choices, but there are some solid options out there.

Finish: While you might want a powder-coated finish to keep standard water bottles from slipping out of your hands, mugs often come with handles instead. However, many of the picks below will have some sort of extra grip, whether or not a handle is included.

Temperature Retention: Stainless steel options will often be vacuum-insulated (an added layer that keeps heat from getting in or out) and keep your drinks either hot or cold for a while. Since heat rises, going for mugs with smaller lids/lid openings will help with heat retention.

Maintenance: Most stainless steel mugs need to be washed by hand, as opposed to putting them in the dishwasher (which you can do with most glass and ceramic mugs).

Leak-Proof/Spill-Proof: As we mentioned up above, most travel mugs advertise themselves as spill-proof, but what does that really mean? Most of them won’t deluge water if toppled over, however, they might still leak if upside down or sideways for any amount of time. It’s important to distinguish the difference, especially if you’re planning on carrying these in your bag.

RTIC Travel Mug

Best Budget Travel Mug: RTIC is a legendary name in drinkware, and in less than a decade. Known for offering unrivaled outdoor-ready gear at affordable price points, this 20-ounce option is not only incredibly cheap but looks like a travel mug that’s twice the price, especially considering the size (there’s also a 16oz size available). Compared a lot to YETI, RTIC still gets the job done with double-wall stainless steel insulation for temperature retention, a no-sweat exterior to eliminate condensation, and a splash-proof flip-top lid with an air-tight seal. Also, it’s dishwasher-safe!

If you’re looking for something simple for transporting your drink to and from work or school, or simply want a desktop vessel that can keep your coffee warm for a while, the RTIC Travel Mug will do the trick, and with a price tag much lower than the competition. Aesthetic-wise, it’s simple and sleek enough that nothing about it looks cheap, and it feels durable in your hand. Despite the plastic lid, which helps you see how much of your beverage you have left, the mug had some of the best temperature retention, only gaining 3.6ºF in 15 hours.

My biggest gripe is the lid itself. Aside from being difficult to open upon first use (also there’s a lip on one side that almost implies it’s a seal-on rather than twist-on), the flip-top always lands too close to the handle when twisted all the way. I suppose if you really wanted to force it, you could make it so the sipper was in a better position, but no one should have to use a vice-grip in order to drink from a lid properly. Also, the handle design is pretty uncomfortable with its thin, sharper edges. Surprisingly enough, the RTIC Travel Mug was actually one of the least prone to leaking on this list. Even without clamping the lid all the way on, not a single drop came out of it when shaken upside down. This can be attributed to the actual effectiveness of the flip-top plug, which is pretty deep, despite being fairly easy to snap on and off.

Verdict: The lid design doesn’t make sense with its twist-on function –– not to mention, it restricts which hand you can grab it with –– but RTIC still makes the best budget travel mug around and has some incredible leak resistance and temperature retention.

Yeti Rambler Mug

Best Outdoor Mug: Since 2006, YETI has been making products (starting with coolers) that stand up to tough conditions and don’t leave you hanging like the mass-produced retail options. Since then, the brand has garnered a lot of popularity among outdoor enthusiasts and people who just appreciate good build quality. And the label’s Rambler Mug is a shining example of this quality, made with double-wall vacuum insulation that’ll keep drinks (and food) as hot and cold as you’d like. This is a great choice for the campsite, and can even be thrown in the dishwasher, unlike most other stainless steel mugs. Plus, it’s stackable, which makes it easier for packing if you have more than one. We tested the 14oz mug, but there are 10oz and 24oz versions too.

We all know YETI’s prowess when it comes to vacuum-sealed water bottles, but the brand is also superb when it comes to other drinking vessels. The smaller size of this 14-ounce Rambler makes it better for sipping hot beverages, as does its sipping lid. The clear top allows you to see how much you have left inside, or you can remove the lid altogether to let your drink cool down a bit faster. After all, the stainless steel construction will keep this hot for much longer than you probably intend it to. Despite the diminutive stature, the Rambler is deceptively capacitious. Aside from the satisfying action of operating the sliding cover over the sipper, the slider itself feels firm when both opened and closed. Other versions of this on other mugs seem flimsy and more prone to leaking. However, after being jostled around a bit, I couldn’t find much leaking coming from the lid or its sipper cover –– only minimal moisture collecting around parts of the edges.

It’s also important to note that the nature of the sealed cap makes it pretty difficult to open up. Sure, this helps prevent leaking but the fact that you’ll have to tilt this at an angle and use force makes it virtually impossible to open when liquid is already inside. Say you just want to top off your coffee or tea –– forcing the lid open when the mug is half full will undoubtedly lead to spillage. The handle feels good in hand and will fit about three fingers when held. Also, the non-twist lid lets you position the sipper hole where you want in relation to the handle for more ergonomic comfort.

Verdict: High on durability, yet relatively lightweight, the YETI Rambler is a fantastic option for drinking coffee and tea on camping trips. Despite being difficult to open with liquid inside, the lid has a sipper hole that isn’t too small, which is great for not burning your tongue on hotter beverages, while the slide opener prevents leaks pretty well.

KeepCup Travel Mug

Best Hot Coffee Mug: After two Melbourne baristas saw how much waste was involved with coffee making and drinking, they decided to make the KeepCup, a reusable mug, that hit the land down under in 2009. Now the KeepCup is beloved worldwide, thanks to the mug’s coffee-friendly design made with tempered glass, a cork band, and a splashproof lid. It even fits under most espresso and coffee machines, so you can get your favorite local coffee to go while preserving its flavor and temperature. It comes in four different sizes: 6oz, 8oz, 12oz, and 16oz, although we only reviewed the 12oz version.

The first thing you’ll notice with the KeepCup is its unique design. While the cork band is mostly for aesthetic purposes, it can also help provide an extra bumper if this thing happens to fall or bang against another item or surface. On the other hand, it doesn’t help much with the grip, yet adds an extra layer of thickness that makes it more difficult to hold in your hand. I wouldn’t complain if KeepCup made a version of its flagship model with a handle. Although it’s made of glass, the mug is one of the most durable-feeling glass mugs we’ve used; I can’t imagine it breaking easily. With a lower hot liquid temperature retention time, the glass wall will also be favorable for those who hate steel mugs that make it difficult to drink hot coffee quickly.

For sipping, the lid opening is triangular shaped and is large enough that sipping isn’t unproductive; this isn’t a Starbucks lid. In the center of the lid is a piece that swivels so that you can cover the opening when you’re not drinking or be turned when you want to leave it open. Even though the plug doesn’t quite “snap” into place like I expected, it also didn’t allow leakage when I turned it upside down and shook it. Likewise, the entire lid itself feels like it’s not incredibly secure. I kept thinking it wasn’t on all the way. However, even when I tossed it onto the ground and let it tumble a bit, only a few drops presented themselves around the sipping hole (which, technically, means it’s not entirely leak-proof, but this is still impressive). I was taken aback when the sipper hole cover piece came off the lid, exposing a giant hole in the center of the lid. Then I figured this would make it easier for cleaning. I just wish it didn’t come off so unintentionally; it was much too easy to over-twist this swivel piece.

Verdict: Overall, it’s a lot of fun to use the KeepCup and it will certainly add a stylish element to your desktop space. We don’t recommend putting this in your backpack with liquid inside but it won’t spill if you’re traveling with it in a car. Glass is an attractive option for quicker coffee drinkers who don’t want to wait for the cool-down times of steel mugs. Even though the lid on this model feels a bit flimsy and cheap compared to other options, the company has the right idea.

MiiR Flip Traveler

Best Mug for Commuting: The independently owned label MiiR is a certified B Corporation with a Climate Neutral certification, and a mission to craft products that benefit not just the user, but the environment. MiiR’s Flip Traveler is a sleek, simple, and effective travel mug that’s perfect for your commute in that it is leak-proof for carrying in a bag, fits easily into your cupholder, and sports an easy one-handed flip top. It’s made with vacuum-insulated stainless steel to keep your drinks at the perfect temp, and even features an insulated spill-proof lid. Additionally, it’s coated in the label’s Hardshell Powder Coat, making it more durable. We took a look at the 16oz model (12oz and 20oz versions are also available).

As we’ve seen with its other models, such as its Insulated Water Bottle, MiiR really knows how to bring subtle design changes to traditional vessels without losing their recognizability as that object. Case in point is this minimal travel mug, which sports a sleek body and an angular design up top. Easy to open for filling compared to other mugs and bottles, the Flip Traveler sports a lid with a flip-top sipper design that snaps into place to prevent leaking. This proved to be almost true upon shaking the bottle upside down, although some drops did come out. Likewise, there’s no equivocality in whether the top is opened or closed thanks to the effort it takes to snap it shut. This is great if you’re carrying the mug inside your backpack or gym bag (although there are certainly better gym options out there). In the way of our testing, the MiiR had the best heat retention numbers and second-best coldness retention numbers.

In terms of a practical drinking vessel, the Flip Traveler may prove to be more impractical than most. The flip-top doesn’t open far enough and bumps into your nose when drinking, preventing you from doing so comfortably. Likewise, if you’re looking for a single-hand mug, the MiiR will be troublesome due to how difficult it is to open its flip-top. It’s almost impossible to do this without two hands, and closing it requires a bit of extra force. This isn’t an issue if you’re leaving it open for a car ride. However, if you forget to close it or merely think it’s closed all the way, you could have a messy situation. Despite the claim that the outer wall was powder-coated, it was highly slippery in my hand.

Verdict: Stylish and fairly leak-proof, the MiiR will give you some issues when it comes to actually sipping your beverage with a flip-top that simply gets in the way and can’t be opened or closed single-handedly. Nevertheless, the Flip Traveler is a solid commuter option for those who don’t want a giant bottle taking up space and adding weight to their work bag. Plus it has the best heat retention and second-best cold retention of the vessels we tested.

Hydro Flask Coffee with Flex Sip Lid

Best Mug Overall: If you don’t already have a Hydro Flask (or somehow have never seen one), then you’re missing out on the Oregon-based label’s outdoor-friendly and durable products. Since they’ve taken the world by storm, Hydro Flasks began receiving new iterations, like this insulated mug here that’s part of the company’s coffee-focused lineup, which is backed by a lifetime warranty. Holding 16oz of liquid (12oz and 20oz options available too), it gives you 12 hours of hot drinks and 24 hours of cold drinks, with a leakproof Flex Sip lid that provides a simple way to drink without spilling.

In terms of hitting all the marks well, this Hydro Flask Coffee is a winner. It’s easy to carry with a comfortable silicone strap attached to the lid and it minimizes spillage when turned upside down. The cap is easy to take on and off, and you can tighten it pretty well if you try. While the powder-coating could be more aggressive like some of the brand’s other options, it has a nice in-hand feel and has solid temperature retention without being too heavy. Perhaps the best part about Hydro Flask aside from its tried-and-true quality is its lid options. Aside from this sip lid, there’s the chug cap, sport cap, and straw cap. However, if you’re really looking for a travel mug, especially for drinks like coffee, the sip lid is the way to go. It might not be as pleasant to physically sip from as others on this list in terms of the flow of the liquid, but it’s better for hot beverages and seems to slow down liquid on its way to your mouth.

The biggest downside of the Hydro Flask Coffee is how difficult it is to open while driving. The twisting operation of the sip lid requires two hands and has a good deal of resistance even then. However, this can be remedied if you simply leave the cap open on your car ride. Plus, if you forget to close it back up, the depth of the lid will minimize most incidental spillage. On the other hand, when closed properly, this bottle proved to be leak-proof when shaken upside down. Some users have noted that if the silicone strap breaks, you have to replace the entire lid. But the sturdiness of the strap makes it hard to imagine it getting damaged in the first place.

Verdict: Benefitting from top-to-bottom construction excellence, the Hydro Flask Coffee has decent temperature retention, a stylish aesthetic, and multiple lid options. It’s difficult to open and close single-handedly, but the advantages of this vessel far outweigh its drawbacks.

Contigo Travel Mug

Best Mug for the Car: It’s ideal for the commuter thanks to the simple, one-handed flip design. The brand’s patented Autoseal technology allows the sipper to open up when you need it with the push of a button, but even more, it closes automatically so you can’t accidentally forget. It is guaranteed to be completely leakproof whether you are shaking it, rocking it, or rattling it. Stands up to the worst you can throw at it for those times when you just need a little caffeine after you roll your car. Works for both righties and lefties with equal ease. Large enough for even the hardiest coffee fiend and simple to use at 24 oz (16oz and 20oz options available too). If you need style and substance without dropping a lot of dough, the Contigo has you covered. Comes with a lifetime warranty against defects and provides up to 5 hours of hot drinks and 12 hours of cold drinks.

Car mugs are hit or miss, and many of them are great in one regard but terrible in another. However, the Contigo Travel Mug doesn’t have a lot of flaws, at least not where driving and (non-alcoholic) drinking is concerned. The Autoseal is a great feature that allows this mug to be spill-proof while also making it fun to use. You literally just press the Autoseal button firmly and sip from a hole on the other side. Also, the flow of the liquid was pleasantly paced. This is one attribute that can’t get controlled a whole lot with simple openings in a lid. However, the canal shape required of this particular contraption allows it to have a unique drinking experience.

While it’s spill-proof, it’s not technically leak-proof when the Autoseal is unlocked. Shaken upside down, quite a few drops still came out, but this shouldn’t be much of an issue if the bottle just topples over on the table. On the other hand, if you use the Autoseal lock, this mug is about as leak-proof as they come, just like the brand claims. I do wish, however, that the Autoseal lock were easier to press. It often got stuck when wet and I had to use two fingers to push. While the 8.3ºF temperature gain over 15 hours isn’t bad, it’s still the worst of the ones tested. I was honestly surprised it did so badly considering the density of the lid. But upon further inspection, it makes sense because the seal itself isn’t terribly wide.

Verdict: Not many 24-ounce travel mugs can fit inside cupholders as well as the Contigo Travel Mug. Add to that the ability to seal the drinking spout automatically when not in use and you have yourself the ultimate car ride sipper. Priced fairly, this mug really doesn’t have a lot of flaws outside of below-average temperature retention. However, it will still serve most people’s needs just fine.

JoeVeo Temperfect Javabliss 16 Travel Mug

Best Coffee Mug for Instant Sipping: A big issue with travel mugs when it comes to coffee or other hot drinks is the inability to drink right away. In a standard coffee mug, the liquid cools down instantly and most people drink it fast enough that it can retain a level of warmness the entire time. But if you need coffee on the go, the temperature retention of most steel vessels prevents you from sipping for hours unless you pour it into a separate mug for drinking. However, this Temperfect from JoeVeo uses an innovative system that brings the temperature down to a drinkable level in just 3 minutes AND keeps it at that drinkable level for hours.

Obviously, when a product makes a claim such as the JoeVeo, it’s natural to try and see if it can follow through. As such, to test this specific mug, we checked the temperature right as the coffee was poured and then again 3 minutes later (with the lid on). In that short amount of time, the coffee went from 162ºF to 146ºF –– pretty impressive. I wanted to see how much it would drop after 5 more minutes, this time with the lid open. Lo and behold, the temperature stayed relatively the same, this time hovering around 144.5ºF. If you’re someone who likes to drink coffee quickly, this might still be too hot, compounded even more by the fact that it’s being held at that temperature indefinitely, more or less. On the other hand, coffee sippers will love how drinkable their beverage is in such a short amount of time.

As far as the drinking experience, the anti-slosh sipper shutter isn’t terribly reliable when it comes to leakage. It’s essentially the same effect as if you were to use your finger to cover the opening –– although the brand acknowledges this in the product description online. Likewise, the lip of the lid is just slightly too deep for sipping comfortably. From an aesthetic standpoint, the JoeVeo has an attractive design language, with a silicone sleeve that provides a firm grip in your hand. I also like the silicone base, which eliminates noisy set-downs on your desk. However, as someone with a caffeine addiction, 16oz is a bit small for me (I drink around 64oz of coffee per day) so I would have loved it if there were a larger size option.

Verdict: Poor lid execution aside, the JoeVeo sports an attractive design and stays put in your hand with a silicone grip. It will definitely leak and is difficult to sip from but the mug follows through on its promise to deliver drinkable hot coffee in just three minutes.

Stanley Quencher H2.0 FlowState Tumbler

Best Large Mug: This is probably the cup your dad used (and still uses) whenever you went camping as a kid. However, we’ve all seen how trendy Stanley Tumblers have become with the younger crowd in today’s viral society. But don’t let the trends fool you; Stanley is a heritage brand through and through, around since 1913, when the founder brought vacuum insulation and steel together to create a rugged cup that can stay hot. You can also trust that the historical quality of this brand translates to its insulated travel mug. It’s made with recycled materials, and the label’s FlowState lid, which offers a full cover top, a drink opening, and an opening for the included straw so it doesn’t spill while using it. Additionally, it’s dishwasher safe and comes with a lifetime warranty. For those who drink a lot during the day and want minimal refills, this 40-ounce option is a great pick, although it’s available in several sizes from 14oz to 30oz.

It’s easy to deride a product that’s become a fad but Stanley’s Tumbler makes it so difficult. For starters, the sheer design that intuitively allows for 40oz of liquid to be held in your car’s cupholder is brilliant. The tapered bottom half has made this mug desirable in and of itself. I also liked how comfortable the handle felt in my hand. Wisely, it’s a different, softer material than the steel mug, which is a crucial element with a thermos this size because it can get quite heavy. As for the cold temperature retention, this mug actually lost degrees over 15 hours and was the only one that still had ice left inside.

As nice as it is to have options between a sipper and a straw, the actual application of this feature is a bit gimmicky. The triple-function lid does not open and close very easily, which can be an issue when you have a full mug of coffee on a bumpy car ride. It almost always requires two hands to operate. Likewise, if you’re out for the day and have decided to switch from the straw to the sipper, you’ll have to find a place for the straw in the meantime. A remedy for this requires you to make the executive decision of sipper-versus-straw before you leave the house. Likewise, the sipper opening is a bit too close to the handle, just like the RTIC above. However, it doesn’t disable you from sipping outright, and at least you’re able to drink this while holding it with your right hand (the cupholder side). Another important thing to note is that the Stanley is in no way spill-proof, let alone leak-proof, and was the only one in this guide where lots of spillage occurred when it was tilted upside down. It was pouring out water even lying on its side. The lid loosens far too easily, which can be a major issue for a lot of people.

Verdict: Stanley’s Quencher H2.0 FlowState Tumbler may be the most trendy on this list but it definitely delivers in a lot of ways. The unique design lets you easily travel with 40oz of your beverage of choice and the phenomenal cold temperature retention is a big plus. Not to mention, the handle is comfortable to hold despite the heavier weight of the tumbler. We didn’t love the lid necessarily, which isn’t spill-proof, but this might not be an issue if you love everything else this mug can do.

Travel Mug Comparison Chart

Why Use a Travel Mug?

With the myriad options of insulated water bottles these days, one might wonder why a travel mug is a preferable option. Well, for one, mugs are better for hot liquids for their ability to sip rather than chug. Smaller holes on top give you the ability to nurse your coffee or tea rather than meet a daily goal, like you would with water. Likewise, mugs are usually much smaller, which is also better for beverages you don’t want a lot of. On the other hand, you wouldn’t be blamed if you wanted to bring along an insulated water bottle AND a travel mug –– in fact, a lot of people do it.

Single-Wall Vs. Double-Wall Vs. Triple-Wall

While a vast majority of stainless steel bottles and mugs are double-wall insulated, you’ll come across single- or triple-wall options every so often. If you’re wondering what double-wall means, it essentially refers to the two layers of stainless steel that have had the air between them vacuumed out in order to limit heat transfer. On the contrary, triple-wall insulation doesn’t mean a third wall of steel but actually a layer of copper between the two steel walls, which helps further insulation. Although the jury is still out on if this is actually necessary or just a marketing ploy. As for single-wall insulation mugs, these may be appealing to those who don’t care as much about temperature retention and want something a bit lighter in weight.

Honorable Mentions

One popular budget option is Zojirushi’s Stainless Steel Mug, a cupholder-friendly flip-top thermos with interesting tech that includes partial vacuum construction which allows for some air between the two walls. The Contigo is similarly priced and has some better features, but the Zojirushi is a popular choice as well.

While the Carter Wide Mug from Fellow has a great design and construction, we preferred the similar YETI Mug above. It’s a popular choice for its aesthetic and performance but lacks a handle and can’t fit in most cupholders.

BruMate’s NAV 22oz is a great choice with its extra capacity thanks to the contoured shape. The company always comes to the party with innovation and originality. However, their products always seem to get discontinued quickly, which prevented its inclusion here.

Despite its design-forward silhouette, the Kinto Travel Tumbler narrowly missed the cut because it lacked a lot of desirable “travel” features, such as a handle and an actual sipping lid, meaning you have to remove the entire lid to sip from it — not ideal. 

Another option that’s more form than function is the Hitch Bottle & Cup Kit, which sports a cool industrial minimalism but feels impractical for actual traveling.

The Best Insulated Water Bottles

While we love travel mugs for our coffee and tea on the go, we need much more capacity for our hydration needs. Take a look at our best water bottles guide for H20-specific solutions.
