Unsurpassed commitment to quality and design means that when it comes to keeping it hotter, cooler and fresher, no one does it better then thermos. Thermax vacuum insulation virtually eliminates temperature change by creating an airless vacuum space between two stainless steel walls. The result is an insulation layer that performs better than any other. A superior insulated container you can depend on to keep your food and beverages hotter, colder, fresher longer. Conserve. Preserve. By using your Thermos brad product instead of dipsosable containers to carry food and beverages, you can help reduce the food and packaging waste that is sent to landfills each year. Small changes make a big difference.
