We’ve reviewed the best thermos for coffee and hot drinks that lets you sip on the go, so you can take your delicious barista-quality drink with you at all times.

These travel mugs should be well insulated, comfortable and convenient to carry, and durable enough to last for many years of daily coffee drinking.

With that in mind, we’ve found some recommendations for the best travel mug on the market to suit any caffeine lover.

Winner: Yeti Rambler

YETI Rambler 20 oz Tumbler

The best insulated coffee mug is one that’s simple, cool to look at, and adept at keeping your drinks hot inside.

The Yeti Rambler ticks all of these boxes and more with a 20 oz capacity for all types of drinks, a secure lid, and BPA free construction that can easily be cleaned in your dishwasher if you’re feeling lazy.

They come in a range of bright colors to suit your personality and the right amount of insulation for keeping your coffee hot.

What makes this the best thermos for coffee and other hot drinks is the MagSlider.

This patented feature was designed by Yeti to ensure your hot liquid stays securely inside of the thermos.

It does this with the power of magnets that keep the lid shut tight, so you don’t have to worry about spilling hot coffee on yourself ever again.

The only real complaint that customers had was the size, with some finding that 20oz of liquid capacity was too much.

The thermos itself is a little wide and if you already have petite hands it could be uncomfortable to carry, although customers did note that it fits in standard sized cup holders.

At 6 7/8 inches high and with a lip diameter of 3 ½ it doesn’t seem that large, but getting a good grip might be difficult for some.

Other cool features include the durable color coating that withstands high temperatures and dishwasher cleaning. It also features a no-sweat design for zero condensation, regardless of whether you’re drinking hot or cold drinks.

The Yeti Rambler is made with durable 18/8 stainless steel on the body and a BPA free plastic construction on top, giving it the strength to keep your drinks at their ideal temperature.

This is by far the best portable coffee mug on the market and it’s no wonder that Yeti has already earned themselves this solid reputation.

Priced at around $30 on Amazon and coming with free shipping if you’re part of Amazon Prime, it’s a worthwhile investment that should last many years and cups of coffee.

The Yeti Rambler is our pick for the best travel coffee cup, even if it is a little on the large side.

Runner Up: Thermos Stainless King

Thermos Stainless King 40 Ounce Beverage Bottle

The Thermos brand is responsible for bringing these devices to the masses, so it makes sense that one of their travel coffee mugs makes our top list.

The Thermos Stainless King can hold up to 40 ounces of liquid inside and it works just as well or hot and cold drinks, keeping them their ideal temperature for 24 hours.

It features a durable stainless steel body and interior which keeps it cool to touch but hot inside where it matters.

The Thermos Stainless King is a no frills type of travel coffee thermos providing powerful insulation that’s easy to enjoy.

The best thing about it is the lid which doubles as a serving cup so you can drink your coffee wherever you might be, all the while keeping it as hot as ever thanks to the insulated lid.

There’s also a stopper inside the lid so you can twist and pour your drink without anything spilling, making it the most practical choice we’ve found.

In terms of longevity, some people found that after a year of use their Thermos wasn’t keeping beverages as hot as they should be.

While this might not be a problem for everyone, it does make you want to spend a bit more getting something with a lifetime guarantee.

Wash with care and keep it dried out when not in use to try and lengthen its life span even more by keeping the vacuum insulation function working.

The Thermos Stainless King measures 12.3 inches high so it’s a good size and it weighs less than a pound, so it’s not too bulky to take to work or on the train.

This travel mug comes in five different colors including army green and cranberry, so you can get one to suit your style.

There’s also a fold-flat carry handle that makes it easy to transport and ensures no spills when you’re pouring out a cup of hot coffee.

If you’re more about function than style, you’ll love everything about the Thermos Stainless King.

This 40oz tumbler is the best thermos for coffee that actually stays hot, and you can get one from Amazon for around $20 plus postage.

For this price and the modern vacuum technology that Thermos uses, it’s a top choice for those who have to travel long distances and want to ensure their coffee stays hot.

Alternatives: Stanley Classic Vacuum Bottle

Stanley Classic Vacuum Insulated Wide Mouth Bottle

If you’re someone who likes a lot of coffee, you’ll want the best insulated coffee mug that can handle your caffeine needs.

The Stanley Classic Vacuum Bottle holds a whopping 64oz of either hot or cold liquid so you’ll never go thirsty again.

Using vacuum insulation, it keeps drinks hot for 32 hours and cold drinks icy for a massive 160 hours.

The construction is naturally BPA free and made from 18/8 stainless steel so you never have to worry about your coffee travel mug rusting away.

The best thing about this thermos was just how long it kept drinks at their ideal temperature.

Compared to other thermos bottles that claim to do the same, the Stanley worked longer at keeping a coffee hot.

However, you need to limit the time you have the lid removed as this can affect the overall temperature, but otherwise, it should last over a full day providing you with piping hot coffee.

There were a few drawbacks that prevented this from being the best travel mug for coffee, including the lack of insulation of the lid.

This means if you pour yourself a drink from the thermos you’ll still feel the heat because it’s not insulated.

The size is seriously bulky, weighing around 2.5lbs for the bottle alone.

Considering this was one of the most expensive travel mugs, something lighter would’ve been better to see.

The Stanley thermos comes with a cool retro design and collapsible handle so you can carry it with you wherever you go.

It has a leak-resistant lid so even if it’s sitting upside down in your backpack, you don’t have to stress about spillage.

The extra wide mouth of the thermos makes for easy consumption and pouring, and the attached lid can even be used as a cup for drinking your coffee.

As mentioned though, the lid isn’t insulated so you may need to protect your hand against the heat that comes through.

This is a durable coffee thermos that ticks all of the boxes and provides the best insulation for long term use.

To get your Stanley Classic Vacuum Bottle you can head to Amazon and grab one for around $35 thanks to a current sale.

It features a lifetime warranty which vouches for its high quality, so if you’re happy to spend extra this would be a wise investment.

Alternatives: Fijoo Stainless Steel Thermos Bottle

Stainless Steel Thermos Bottle

If you want something super insulated but don’t feel like spending a lot of money, the Fijoo Stainless Steel Thermos Bottle might be the budget-friendly option for you.

It’s a no frills solution to hot, portable coffee and comes in either 34oz or 17oz sizes depending on how much you drink.

Made from durable stainless steel and with a screw-on top to keep the insulation intact, you’ll be able to enjoy either hot or cold drinks for hours to come.

The best thing about this is the special insulation system, making it a standout compared to other more expensive options.

It features two stainless steel walls with an extra copper lining in between them so you have a triple wall of insulation at work.

You’ll be able to keep herbal teas, coffees, hot chocolate, and any other hot drinks inside, and it works just as well for iced drinks.

Cleaning this thermos can be a pain and you’ll need a specialized brush tool to get inside of it.

Some users have also found the stainless steel exterior to be prone to scratches as well.

Although the inside will continue to work and keep your drinks at their desired temperature, the outside appearance might not be so pleasant to look at.

Other notable features of the Fjioo Thermos Bottle include the screw lid that doubles as a cup.

You’ll be able to drink hot coffee on the go or straight out of the bottle, thanks to the extra-wide mouth opening.

The bottle fits perfectly inside a standard cup holder and has a leak-proof lining which prevents anything from spilling.

There’s no plastic interior or BPA and no metallic aftertaste, so it’s made with the best materials possible.

The Fijoo Stainless Steel Thermos Bottle is ideal for people who don’t care about the look of their travel mug, just that it performs well.

There’s no warranty offered which is to be expected for the low cost, so you’ll want to be extra careful with it.

Priced at less than $20 on Amazon for the smaller 17oz, it’s a bargain, and will not only give you somewhere to keep hot coffee but also enjoy icy cold drinks on a hot day.

Alternatives: Zojirushi Stainless Steel Mug

Zojirushi SM-KHE48BA Stainless Steel Mug

When you want your travel coffee mug to be as equally stylish as it is functional, something like the Zojirushi Stainless Steel Mug will be the right choice.

Coming in a range of vibrant, modern colors, this stainless steel thermos can keep hot and cold beverages at their ideal temperature for hours.

This mug is made with SlickSteel, an 18/8 stainless steel that’s been electropolished to create a corrosion-resistant surface, so it’ll never fade or scratch and it’s incredibly lightweight at just 9oz.

The best thing about this stainless steel mug, other than the cool design, is the unique lid.

It features a flip mechanism that lets you drink with ease while also keeping everything locked securely inside, so there’s no need to worry about spilling your coffee.

Because it’s corrosion-resistant you can keep it in your bag and it’ll never get scratched, further adding to its cool look.

The Slick Steel also helps with insulation and allows you to take drinks of all temperatures inside.

Compared to other thermos products, the heat retention offered by Zojirushi, unfortunately, doesn’t come close.

According to their standards, it can keep a hot coffee at 154 degrees for up to six hours, so if you plan on drinking it any later, you’ll want to upgrade to something else.

This would better suit someone who wants a hot coffee on the commute to work and not someone who stores theirs overnight or after a long shift at work.

As far as cold drinks go, it does perform a little better at keeping them cool.

This stainless steel thermos features a wide mouth opening for easy drinking and a compact size that fits easily wherever you need it to.

Champagne gold, cherry, and lavender pink are just a few of the cool colors you can choose from for your Zojirushi Thermos, making it one of the prettiest travel coffee mugs around.

The Zojirushi Stainless Steel Thermos is pricier than others on the market, at around $45 for the 16oz bottle, or $25 if you’re able to shop it on sale at Amazon.

There’s a five year warranty on the insulation parts which gives you peace of mind, and it’s guaranteed to keep its stylish look for years to come.

This is the perfect coffee travel thermos for those who care about looks and want a mug to match their stylish personality.

Holding And Drinking Coffee From Mug

Drinking out of a thermos is something that’s been done over 100 years, and even though we use these insulated bottles every day, there’s still a lot we don’t know about how they work.

Check out the answers to some commonly asked questions about the travel coffee thermos for a better understanding.

What Is A Thermos Actually Called?

A thermos is sometimes referred to as a vacuum flask, in reference to the technology used to keep the drinks inside at their ideal temperature.

The vacuum flask features two flasks with a gap in between them which creates a vacuum and helps to reduce heat transfer, so the liquid inside remains as hot or cold as desired.

What Thermos Keeps Coffee The Hottest?

There’s no singular thermos that does the best job of keeping your coffee hot, but the better models are capable of heat retention that lasts up to 24 hours.

Some models claim to work for 32 hours but you may lose some of the heat during this time, especially if the bottle is being opened.

How Long Does Coffee Stay Hot In A Thermos?

There are a few factors that determine the heat retention of a thermos and how long it will be able to keep coffee hot.

The insulation system, materials used, size, security of the lid, and how often it’s been opened and closed.

Generally, a thermos keeps drinks hot for a minimum of six hours but can be up to 24 hours in more expensive models.

How Do You Get Coffee Stains Out Of A Thermos?

If your thermos has coffee stains you can attempt a mixture of white vinegar with a small teaspoon of baking soda to remove them.

Fill the bottle with vinegar and add the baking soda and then leave to sit a few hours before rinsing it out with warm water.

You should always check the care instructions of the thermos to determine the best methods before attempting a deep clean.

Keeping Your Coffee Hot and Close By

This insulation technology used in thermos bottles has been around for over 100 years now, and it only seems to improve as time goes on.

These days, travel coffee mugs can pair this innovative technology with stylish designs so people can match their coffee carriers to their look, whether you’re a sleek professional or a casual college student.
