Our magic word: VICC® technology.
What makes the FLSK so special? In addition to the cool design, it is above all the outstanding functionality that makes the FLSK stand out from the crowd. On average, normal thermal bottles do not provide more than 6 to 9 hours of insulation. At that point at the latest, most drinking bottles run out of breath - cold tea or lukewarm soda are the unpleasant result.
The FLSK, on the other hand, keeps its contents hot for up to 18 hours and cold for up to 24 hours. Ideal for when you're out and about all day. VICC® technology makes it possible. Here you can find out more about the revolutionary process that is largely responsible for the enormous insulating ability and performance of the FLSK stainless steel drinking bottle .

What is VICC® technology?
Our innovative VICC® technology makes the FLSK a real quality product. VICC stands for Vacuum Insulated Copper Coating. Two components, one goal: to make the insulation performance of the FLSK unbeatable.
-
Vacuum Insulated : A vacuum is a space that does not contain any air. The vacuum layer between the two stainless steel walls of the FLSK insulated bottle prevents heat and cold from escaping. Since a vacuum, unlike air, does not conduct temperature, rapid heating or cooling becomes impossible. The stability of the FLSK is not affected by the vacuum.
-
Copper Coating : A copper coating on the outside of the inner bottle body additionally supports the temperature retention of the bottle. The high-quality stainless steel material of the other drinking bottle components also ensures the longevity of the function.
The use of VICC® technology is currently the most advanced and effective process for the temperature insulation of thermal bottles. It was developed by us and meets the highest technical standards. Unfortunately, VICC® technology cannot maintain the temperature forever. Over time, the heat or cold dissipates - especially through the lid. To counteract this, our bottle caps have a particularly precise fit with a rubber ring. And so the FLSK thermal bottle has an insulating performance that is second to none: 18 hours hot and 24 hours cold.
