Advanced Vacuum Insulation Technology!
James Dewar invented the first vacuum flask in 1892. Double walls mean that the inside liquid compartment is protected from the heat or cold of the outside. Hot or cold drinks are insulated and will hold their temperature for longer. Keep hot/warm drinks for 12 hours and cold drinks for 6 hours.
