Technical information

Advice for optimising 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.


You can open the quick-release cap with one hand by lifting the white latch. You close it by pressing the latch down or by screwing the cup back on.
A removable tea filter is attached to the cap. Simply pull on it to separate it from the cap. Be aware that if you remove the filter after immersing it in hot water, it may be boiling hot to touch.
The cup screws onto the bottle, making it easy to carry around, and is made from double-walled stainless steel with no air space.

Care tips

- Wash and rinse the entire product 3 times with clean water before first use.

For optimal washing and drying:
1. Separate all parts;
2. Hand wash them with soapy water (with a fine brush to get into the nooks and crannies). The bottle is dishwasher-safe but do not put the cap in;
3. Rinse them in clean water;
4. Leave to dry separately, the cap should remain open when drying.
