Technical information

Directions for use

Tritan, like aluminium, is not an isothermal material. Use a specially designed, insulating bag if you want to keep liquids cool in your water bottle. This water bottle can be used for hot drinks but they will cool quickly.
The product can be used with fizzy drinks. Do not put in the microwave or freezer.


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. It also has a filter so you can infuse fruits for example.
The water bottle is transparent and graduated 200 ml by 200 ml to be able to see the remaining liquid.

Care tips

Clean your flask after each use with a conventional washing-up liquid and water. The product may also be placed in the dishwasher if necessary. Warning, when washing in the dishwasher, the stopper seal may come off. If this happens, remember to replace it as it helps keep your water bottle watertight. Let the bottle and lid dry separately and fully.Soak overnight in a mix of bicarbonate of soda and water for deep cleaning.

First use

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