Using a Thermally Induced Vacuum (TiV) manufacturing process, the Lifeventure
Flask is heated to 600°C and then the walls are sealed, ensuring a long
lasting effective vacuum to keep liquids hot or cold for longer.
The
sleek design means flask is easily stored, and the copper coated inner
wall eliminates hot-spots thereby reducing the chance of heat loss.
Features a screw stopper and a stainless steel lid that can be used as
a cup.
