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 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.

Care tips

Dishwasher safe (top + body) Be careful not to lose the top seals. Dry with the top off. The top's seal can be removed for a complete wash and dry.
