Vacuum insulated stainless steel water bottles are known for their great temperature retention capabilities. The vacuum layer between the inner and outer walls of the bottle acts as a barrier to minimize heat transfer, both from the outside of the bottle and the inside of the bottle.

Using vacuum sealed water bottles, whether made of glass or stainless steel helps you keep your water hot and thus saving time of re-heating and saves energy, yours and the planet's. Likewise, it keeps your water cool, rejuvenating you when you gulp it down.

Vacuum-Insulated Layer Between Between the inner and outer stainless steel walls is a gap that is vacuum-sealed. That vacuum seal keeps air from getting in between the two walls. This vacuum-insulated layer keeps your hot drinks hot and your cold drinks cold.

Double-Walled Insulation: Double-walled bottles, such as Nanobot Vacuum Insulated Bottles, feature two layers of stainless steel with a vacuum seal in between. This design creates a barrier that helps maintain the temperature of your beverage, whether it's piping hot or refreshingly cold.
