Vacuum Insulation Technology
The bottles have a double-walled exterior with a vacuum seal between the walls.
This means your drink will stay at its ideal temperature for a long time.
Plus, the exterior will never sweat or get hot or cold to the touch.
Furthermore, the exterior of the vacuum-sealed area is dipped in copper for added insulation.
Copper reduces the transfer of temperature and adds even more insulation to your bottle.
