For over 100 years, Thermos® brand insulated products have been keeping food and beverages hotter, cooler and fresher. Today this commitment continues with an expanding range of innovative, fashionable products that preserve flavor and freshness. When it says Thermos, you know what to expect - they just deliver it in ways you'd never expect. Bisphenol A (BPA) is a controversial chemical that can be found in the lining of food cans, certain water bottles and more. Some researchers have linked the hormone-mimicking chemical to a host of issues including behavioral and developmental effects in kids. Thermos plays it safe, and has made a commitment to only manufacture products that are BPA-free.
