An insulated Thermos flask is a purchase that keeps paying back all year round.
The best vacuum flasks perform a dual role: they keep hot liquid like coffee warm,
and they keep cold drinks like iced water cool,
for those boiling car journeys in the height of summer.
Once you have one in your life, you'll find it accompanies you to the office,
to festivals, on camping trips, and even on holidays abroad.
How do Vacuum flasks work?
In short, they use a double-walled construction,
with the air removed from between these walls,
forming a vacuum. Heat struggles to pass through the vacuum,
meaning liquid stays at a roughly constant temperature.
To help you choose which one to invest in,
we tried and tested a selection of flasks that promise to keep your beverages
colder and hotter for longer,
measuring how much heat was retained or how cool they kept respectively over a period of 12 hours.
