  • Say the word thermos or even vacuum flask, and a few words like, adventure, resourceful and grandparents spring to mind (well this is what came into our heads). It somehow harks back to an era when there wasn't a coffee shop on every corner and if you wanted a hot drink when out and about, then you had to take it with you. Whether you’re out trekking, minding your children in a park or facing a wintery early morning train ride to work, there is something comforting about cradling a little hot cup of steaming coffee. We say coffee, but soup, stew or even a hot toddy (any hot drink that has a cheeky bit of alcohol in it), will work just fine.

Transport upright. Hot liquids can cause scalding.

    How do I remove stains?

Our vacuum flasks are made from top quality stainless steel and have a convenient vegan leather carry strap. They'll keep your hot drinks hot (up to 8 hours) and your cold drinks… yep you guessed it… cold (up to 24 hours).

In todays fast paced, ever changing world, there is something reassuringly consistent, stalwart and dependable about them.

Now for the history lesson… vacuum flasks were first invented by the Scottish (it's cold up there) scientist Sir James Dewar in 1892. They were as useful then as they are today and in our eyes, this makes them a design classic that will last you a lifetime.
