Need to keep your drinks hot or cold for several hours? Our designers have developed this light, hard-wearing and insulated stainless steel flask.

How is thermal insulation tested?

We’ve tested this flask in the lab according to Standard EN 12546-1, at an ambient temperature of 20°C while filled to capacity. The time it takes to drop from 95°C to 50°C (drinks temperature considered warm enough to drink) is 14 hours.

The secret of the insulated flask?

This insulated flask’s stainless steel double wall with vacuum blocks heat by conduction and convection.A thin layer of copper reduces thermal exchanges by radiation.A few tips to improve thermal insulation: fill your flask with warm water for 5 minutes and then replace the water with your hot liquids, then close. The fuller the bottle, the better the heat retention.Warning: the flask is very insulating, so liquids will remain hot for a long time.

Functions

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.
