Technical information

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 flask has a wide opening (6 cm) for easy filling, especially with ice cubes. The cap opens easily by unscrewing it. It has a hinged handle for easy carrying and storage. The flask also has a small watertight slot for your infused tea bags for example, or to store food sachets or supplements.

Care tips

Dishwasher safe (top + body) Be careful not to lose the top seals. Dry with the top off. The flask can be taken apart by hand for complete cleaning, just make sure to remember how to put it back together.

First use

Rinse the entire product 3 times with clear water before using for the first time.
