As a well-established brand you might assume you can rely on Thermos for high-quality products, but our tests show that not all of its travel mugs are created equal.

Our flasks and travel mugs are available in a range of sizes, large enough to hold cups of tea and coffee, soups or any other foods or liquids you may want to keep warm throughout the day. With your new good-quality flask or travel mug, you can also save on the pennies by taking your own tea or coffee with you when you leave the house. Compared to buying your hot drinks on the go, there are big savings to be had! Today, though, we are going to be looking at Travel Mugs. The adventurer’s choice! What to look for in a travel mug

The best travel mugs you can buy in 2023

Before we get into the ‘unspillable’ nature of the Mighty Mug, we should first consider the key travel mug characteristics. It has a capacity of 0.47 litres, which is slightly bigger than the last few items on our list – a good size for a travel mug.

Many of us have experienced our hot drinks going cold after a short time or, even worse, finding they’ve spilled or leaked in your bag. However, with our great selection of flasks and travel mugs, those memories will now be a thing of the past! Say goodbye to leaky, lukewarm drinks and hello to secure, warming flasks. It’s priced towards the higher end of the price range on this list, but it is not far from average. It is a great mug with a really fun feature. It’s also proved impressively watertight. Slightly frilly features include the strangely dubbed “aroma bowl”, which, according to the manufacturer, allows for a “superior drink interface”. This basically means you can test your drink’s temperature by allowing a small amount to be released. It’s a novel little quirk that we really liked. It makes this mug not just a travel mug, but a great mug to have with you at your desk – perfect for people that travel into their offices, particularly those with longer commutes.The mug is only leak-free when closed, and due to the difficulty of opening it, many users are likely to keep it open, thus increasing the likelihood of a spill. But once you’ve conquered the lid, this travel mug couldn’t be better for robustness, temperature retention and style. A great choice for those who like a bit of colour.

And it shows. We start off with how it looks – this is a very attractive bottle. It is sleek and stylish with the curved body, and it is available in a whole host of different colours. It’s like a paint chart – Biscay Bay, Dark Blum, Iced Aqua and…Red. There are plenty more options when it comes to colour, so I am certain that you will find one that you love. Weight: If you are going to be carrying this around with you for a long time, you may want it to be as lightweight as possible

Want tough, leak-free mugs that keep coffee hot for hours? We're here to help with our best travel mug roundup

Next up we have a Classic from a classic travel mug producer – Stanley. Founded in 1913 when William Stanley Jr fused vacuum insulation with steel to make a portable drinks bottle – and they have been developing that original design for over a century since. For a product that has such an emphasis on style, it is surprisingly inexpensive – one of the cheapest products on our list today. They are available in a range of sizes, from 12oz (0.34 litres) to 20oz (0.57 litres) – something for everyone there. Shop our full range to find something to suit you, from bamboo fibre designs to stainless steel flasks, and everything in between. If you're carrying a drink to stay cool and hydrated, our glass water bottleswill do the job. They’re also a more sustainable alternative to single-use plastic bottles.

It is priced accordingly, though. It is the second cheapest product on our list – if you just want to use it in the car or on your commute, then this is a perfect travel mug. Nothing beats a good cuppa first thing in the morning – but what if you're in a rush? We've got you covered with our brilliant range of travel mugs. Our range is great for the morning commute, and you’ll be living more sustainably by avoiding disposable cups. A travel mug also comes in handy if you’re off to the beach or spending the weekend camping. These are all about the look. The iglu cups are all beautifully designed – a lovely bold travel mug, available in a huge range of colours to suit your style. They are fast-becoming a company that gets recognised, so having their logo on your coffee cup will get you admiring nods from fellow travellers. As the number of people that have been able to make better coffee at home has grown over the last decade or so, so has the demand for travel mugs. We can make this coffee, and we want to take it with us.

BPA Free Why it matters

Like the Thermocafe item above though, it should be kept upright – it is not completely leak proof if it is tipped up. Again, this may put some people off as it wouldn’t be suitable to be put in a bag and jostled around. As such, a travel mug will tend to keep your drink hotter for longer than a reusable coffee cup, and a reusable coffee cup will look more like a coffee cup. Also, a travel mug is something that you would happily throw into the bottom of a bag, whereas a reusable cup is made for drinking out of as soon as the coffee is made.
