This tumbler has a double walled exterior with a vacuum between the walls. This means your drink has no medium for the heat or cold to transfer through. Your beverage will truly stay as hot or cold as long as possible. Retire your coasters and koozies. Even filled with ice or boiling water, the bottle will never sweat or get hot to the touch!
Copper Coated Insulation
The exterior of the inner wall, in the vacuum sealed area, has been dipped in copper for added insulation. Copper reduces the transfer of temperature, adding even more insulation to your cup. This technology gives the best insulation of any tumbler on the market!
