The best coffee thermos flasks: top travel mugs

The best coffee thermos

Countless commuters probably praise the day the coffee gods decided to send us the thermos. It is, for the nine to fiver, night shift worker or anyone in between, almost likely the key to arriving to work with a fully functioning brain, so we’ve put together a list of the best coffee thermos flasks to ensure first sip satisfaction, whether you swig from the flask or drink from a cup.  

Thermos are, quite literally, the kings of coffee flasks and they certainly know it, with names such as Thermos Stainless Steel King Travel Tumbler chosen for their product range. Combining excellent ergonomics and clever vacuum insulation, you can rely on a Thermos flask to keep your coffee hot for a good 7 hours, so even the longest commutes are catered for. 

If you looking for a coffee flask to accompany you on car journeys, keep your eyes peeled for the brands that promise no spills or leakages and more importantly, flasks that can be operated with one hand - such as the Contigo Autoseal West Loop Stainless Steel Travel Mug.

For those of you looking for convenience features, ensuring that your chosen flask is dishwasher safe is a good checklist exercise, as not all coffee flasks are. You may also want to consider travel mugs with a silicon sleeve if you are planning to use your coffee flask on the go - our top pick for non-slip handling is the Bodum Vacuum Travel Mug.
