The classic version of the real bestseller - Silver ISO Vacuum Flask. Everything that distinguished this unique thermos is now available in silver.The ISO Vacuum Flask retains the natural colour of the high quality stainless steel from which it is made. The special coatings inside the thermos flask allow easy removal of sediment and increase the thermal properties of the thermos.Fortunately, the colour change has not been accompanied by a change in shape and the ISO Vacuum Flask thermos still features high ergonomics - making it easier to handle the thermos or to stick it in an unpacked backpack. This has been ensured regardless of the capacity - all sizes have almost the same diameter (only the height varies).The thermos can be used for both hot and cold liquids thanks to the vacuum between the walls made of the best quality stainless steel. Regardless of whether you pour freshly brewed tea or a strong iced isotonic drink, the poured liquid will remain close to the initial temperature even after many hours.The dilemma between tradition and automation is also solved in the ISO Vacuum Flask version - the Esbit comes with two connectors - classic and automatic. They can be used interchangeably depending on your taste and your needs at the moment. In addition, Esbit thermos flasks are also equipped with a second cup that is carried under the cap. Thanks to this, two people can enjoy a warming drink at the same time.The classic - silver version of the colour scheme will certainly be appreciated by all traditionalists.Features:stainless steel double wall coated with a thin layer of copper (antibacterial, insulating)two connections (automatic and traditional)
