Our magic word: VICC® technology.
What makes the FLSK drinking bottle so special? Aside from its cool design, it's primarily the superior functionality that makes the FLSK drinking bottle stand out from the crowd. Ordinary thermos bottles typically offer insulation for 6 to 9 hours. Most bottles lose their effectiveness after that—resulting in cold tea or lukewarm lemonade.
The drinking bottle, on the other hand, keeps its contents hot for up to 18 hours and cold for up to 24 hours. Perfect for a full day out and about. The VICC® technology makes this possible. Learn more here about the revolutionary method responsible for the remarkable insulation and performance of the FLSK drinking bottle made of stainless steel.

What's behind the VICC® technology?
Our innovative VICC® technology makes the FLSK drinking bottle a true quality product. VICC stands for Vacuum Insulated Copper Coating. Two components, one goal: making the FLSK drinking bottle's insulation unbeatable.
-
Vacuum Insulated: A vacuum is a space that contains no air. The vacuum layer between the two stainless steel walls of the FLSK insulated bottle prevents heat and cold from escaping. Because a vacuum, unlike air, does not conduct temperature, rapid heating or cooling is impossible. The stability of the FLSK drinking bottle is not affected by the vacuum.
-
Copper Coating: A copper coating on the outside of the inner bottle body further supports temperature retention. The high-quality stainless steel material of the other bottle components ensures long-lasting functionality.
The use of VICC® technology is the most advanced and effective method for temperature insulation in thermos bottles. Developed by us, it meets the highest technical standards. Unfortunately, even VICC® technology cannot maintain temperature forever. Over time, heat or cold escapes, particularly through the lid. To counteract this, our bottle lids have a precise fit with a rubber ring. Thus, the FLSK thermos bottle has insulation unmatched by others: 18 hours hot and 24 hours cold.
