QUECHUA 0.4 L insulated stainless steel bottle with tea filter, for hiking and camping | Isothermal bottle

Need to keep your drinks hot or cold for several hours? Our designers have developed this practical, insulated bottle.

How is heat 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 (drinking temperature considered warm enough to drink) is over 23 hours.

The secret of this insulated flask?

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

Functions

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.
