Hello Nigel,

Insulated drinking flask

Got this flask given to me as a present and just love it . I drink lots water but when out and about it’s not always possible to have a cold drink but this flask is fab when you put drinks in cold then if want keep it very long add little bits off ice. . It has kept cold for 2 days . And now also decathlon are doing a litre one which is great when we both out as a couple as it also takes hot drinks . Brilliant for all types off activities . So well done and thankyou Decathlon ., as flask especially smaller one goes everywhere with me I also purchased one for my little 7 year old granddaughter as she’s always out doing outdoor sports and always loves water with her .

So many issues!

Mine leaks & certainly doesn’t keep its contents temperature cold or hot for long. Not happy

Very good product, and love it .

First when I bought, just want to try, make sure the flask works. And when I used it yeah it’s works, even over 12 hours the water still warm and that’s what I need, and price reasonable as well

Advice to maximise the performance of your isothermal bottle.

The fuller the flask, the better it is at keeping the contents hot or cold.Be careful when using hot liquids, the flask is extremely well insulated, liquids will remain hot for a long time!We use a double stainless wall with a vacuum between to block thermal exchanges by conduction or convection. To block exchanges by thermal radiation, a fine layer of copper covers the outside of the inner wall.


The top is easy to open with one hand by pressing on the white button marked "PRESS". When carrying the flask, you can lock this button by sliding the white button down. A red area appears, indicating that the top is locked and it can no longer be pressed.The top has an integrated filter to keep large tea leaves or infused fruits out of your cup. Not suitable for very fine cut teas.
