Thermos Mugs the original Travel Mug and the best based on the original vacuum flask invented by Sir James Dewar in 1892. Two glassblowers named Reinhold and Albert were the first to incase the vacuum flask in a stainless steel outer. The product was patented, and the Thermos company was born in 1904.
Today Thermos Mugs are available in a range of designs, colours and sizes. All travel mugs are cool to the touch when used with hot drinks and sweatproof when used with cold drinks.
All Thermos Mugs come with a five-year guarantee.
