Impressive Insulating Property of the Vacuum Bottle
When it comes to thermal insulation properties, vacuum bottles will outperform regular bottles. This is because there is a vacuum layer between the inner core and the outer wall of the bottle which prevents heat in the liquid core from escaping hence keeping cold or hot drinks for longer. This makes using vacuum bottles handy wherever you go, while doing activities outdoors, or for even long ranges with no access to a fridge or even an electric heater.
