Our next recommendation comes from Contigo and is their West Loop insulated travel mug which features vacuum sealing technology alongside a convenient quick-press button designed to allow users to operate and drink with just one hand.

Besides all of that, the West Loop from Contigo can also keep drinks hot for up to 5 hours or cold for up to 12 hours thanks to the introduction of Thermalock Vacuum Insulation. We think it’s an excellent choice for busy professionals. Combining both high-end functionalities with fabulous contemporary looks. It’s intuitively designed and has a modern shape which is very streamlined and attractive. The ability to operate with just one hand is also a real winner, thanks to an easy-press lid button.

Our next best thermos recommendation also happens to be our Premium Pick although there are some great prices to be found online right now for this model, so it’s never been a better time to invest in a new stainless steel mug. Coming from Stanley, it’s very much in the classic vacuum bottle style and is a fabulous choice for coffee connoisseurs who want a truly customizable thermos rather than being stuck with limited options. Featuring a side handle for easy and reliable carrying, the handle can actually be packed flat making the Stanley a perfect choice for traveling and storing too. It’s also great when you are on a road trip as the lid doubles up as a coffee cup, so there’s no need to invest in a separate mug.
Stanley produces their highly popular thermos bottle in many convenient sizes so if you are the kind of person who loves more than their daily quota of hot beverages, then Stanley will have just the perfect size for you. Whether that’s 16-ounce or even a whopping 2.0 quarts, the Stanley Classic has got you covered. For people who appreciate quality and variety, it offers an excellent choice. While it might not come in quite so many fun and contemporary colors as many of the other brands, Stanley has two very distinctive, and we think highly desirable options. Choose from either their Hammertone Green or Hammertone Navy. There’s something reassuringly retro and very comforting about this Stanley Classic Vacuum Bottle.
As if all the above wasn’t already recommendation enough, it’s also leak proof and comes with a lifetime warranty, so there’s little wonder we made it our Premium pick. The Stanley brand has been around since 1913, and their entire range of products looks and feels nostalgic and conjures up that sense of familial tradition, passing down prized possessions through the generations. With vacuum insulation a standard and all the products featuring naturally BPA-free materials, a Stanley Classic is also a wise choice.

Our next Best Coffee Thermos recommendation is a real beauty coming in quite literally all the colors of the rainbow along with some beautiful designs too. We fail to see how there can’t be a Summit coffee thermos to suit even the most discerning and stylish among you! They do actually have a design called Rainbow and a very chic design with anchors on it which is nautical but nice! If you prefer something more subtle though, they also come in a host of more contemporary and classic color choices like Midnight Black and Graphite Grey.

You will receive both their classic Stainless Steel Lid as well as their Splash-Proof Flip lid which is ideal for hot beverages. A series of other interchangeable heads are also available to purchase separately if you prefer a straw lid or a chug lid for example.

We’re concluding our round up of the Best Coffee Thermos with a final recommendation from the market-leading brand, Thermos, again. This time we’re looking at their Sipp 16-ounce drinking bottle which has to be one of the most stylish and elegantly designed ones currently available. It features a chic and sleek design and comes in a range of beautiful metallic colors which all feature a hygienic push button lid that not only looks great but allows for that all-important one-handed operation. The smooth glow design also helps to control the flow of warm liquids and the vacuum insulated technology will keep fluids hot for 12 hours or cold for 24 hours.
It’s durably constructed from stainless steel and dishwasher safe too. The 16-ounce will hold 480ml of liquid so is perfect for daily use. Besides the stunning metallic choices like Gold, Rose Gold, and Silver there are also some lovely matte block colors including Turquoise, White, and Pink along with your regular color options like Black and White. It’s eye-catching, functional, and virtually unbreakable. Both the lid and the bottle itself are easy to care for and use and like we said, can be popped into the dishwasher but are also stain resistant.

Lids not the most durable
The DuraFlask Explorer Bottle is one of the most popular Thermos-style flasks on Amazon for keeping drinks cold. As you’ll see in the customer review section on Amazon, customers are often blown away at how effective it is. But the same technology that keeps drinks cold can also be used to keep your coffee, tea, or soup piping hot. The design consists of three thermal optimizing layers. Most thermal flasks have two layers (that’s at the heart of the Thermos design), so this bottle goes a step further, allowing it to retain temperatures for even longer. They don’t state exactly how long it will keep drinks at the right temperature but we wouldn’t be surprised if it was between 12 and 24 hours (even if you’re in a particularly hot or cold environment). The double-wall insulation creates a vortex of temperature control between the inner and outer layers of the bottle.
Made from 18/8 stainless steel, it’s also super tough. This particular type of stainless steel is rust-proof, scratch-resistant, and won’t dent easily if you drop it. Of course, it’s not completely indestructible, so don’t push it to the limit. We’re also happy to report that the design is leak-free, so there’s very little chance of it leaking all over the contents of your backpack. Plus, it doesn’t give your drinks a weird metallic taste like some cheaper thermal flasks do.

Coffee Thermos Buying Guide & FAQ
It's a category that's filled with choice so before you go ahead and buy your next coffee thermos, have a think about the key features that are most important to you. They're likely to be things like ease of portability, size and volume as well as the overall insulating properties. We've just highlighted a few we think are essential to consider.
Size and Volume - are you a single-serve kind of person, or do you like to sip and savor all day long? There's no point buying something that's too bulky if you're not going to utilize the capacity but ditto, there's nothing worse than wishing you had just that one cup of hot coffee left in your flask. Choose the size and volume carefully to suit your regular needs.
Insulation Properties - vacuum insulating technology means that beverage containers are better than ever before at keeping your drinks hot and cold for longer. Check out the thermoses shelf life when it comes to heat retention, especially if you want something that will keep your coffee warm all day and not just for a few hours. Some can do the job for 24 hours, others for around five so decide which you need. On the whole, most will feature double-walled stainless steel construction which has the added benefit of also being cool to the touch while preventing liquids from sweating.
Delivery System - it's a simple enough observation but many people might forget to think about how the coffee gets from the flask into their mouth! You don't want to be spilling hot coffee or soup all down your chin on the commute into work. Do you prefer to have a detachable drinking cup built into the design? Would you like a sipping hole or adjustable mouthpiece or a simple twist and unscrew lid? How you manage and operate, as well as seal and store your Thermos while you're traveling are important features to consider.
Leak Proof and Spill Proof - these two features are not both a guaranteed and you don't want to find out the hard way after throwing your Thermos into your gym bag only to retrieve wet coffee strained shorts that your lid is most definitely not leak-proof! The best coffee flasks should, of course, be able to withstand wear and tear and everyday rigors but to be absolutely sure, go for something that you know has been adequately drop tested and which features a leak-proof seal among its key selling points.
