DOUBLE-WALL VACUUM INSULATION
Stanley ’ s legendary thermal performance all begins with our Double-Wall Vacuum Insulation technology . By removing the air between the inner and outer walls of our vacuum insulated products , we greatly reduce the thermal transfer between the outside environment and the contents of the bottle . The insulation effect of double wall vacuum insulation allows beverages to stay hot or cold longer compared to traditional drinkware or food storage containers without this technology .
