At the start of it all in 1904, the founders domesticated the vacuum insulation technology, creating the first Thermos® product. A product that would quickly become a staple in the lives of adventurers, explorers, and everyday folks like us. With over 100 years dedicated to providing reliable products, Genuine Thermos® Brand remains just as committed today to helping you to Protect What You Love™.
