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. Supplied with two stoppers - a one touch stopper and a simple screw top stopper, plus a stainless steel lid that can be used as a cup.
