Frequently Asked Questions
Vacuum insulation helps maintain drink temperatures for much longer than drinkware with single or even double walls. Without getting into too much of the physics, a gas-tight vacuum layer is sealed between inner and outer layers of stainless steel. This design works to prevent the ideal temperature of your beverage from escaping, and keep outside temperatures from getting in.
A copper lining is used within the vacuum insulation to maximize temperature maintenance. You can't actually see the copper lining because it is inserted in the gas-tight vacuum between the inner and outer layers of stainless steel. The result is a superior construction which keeps drinks hot or cold for long periods, regardless of outside temperatures.
