Thermos Ultimate Flask 0.75 L

The Thermos Ultimate series insulated flask is engineered for extreme outdoor conditions, offering superior vacuum insulation performance to keep beverages hot for up to 12 hours or cold for up to 24 hours.

The Thermos brand originated in Germany in 1904 following the invention and commercialization of vacuum-insulated flasks by Reinhold Burger and the founding of Thermos GmbH. Over the century, the Thermos brand name spread globally, becoming an internationally recognized pioneer in thermal food and beverage containers.

Today, Thermos L.L.C. and related global Thermos brand operations are owned by the Japanese industrial gas and consumer goods corporation Nippon Sanso Holdings Corporation (formerly Taiyo Nippon Sanso Corporation). While product research and development are led collaboratively across Japan and North America, mass production is primarily conducted in specialized manufacturing facilities in China and other Asian hubs.
