FLSK das Original Trinkflasche

Everyone knows them, nobody wants them: unattractive, heavy, low-quality, and leaking water bottles. So far, no water bottle has been available on the European market that simply works and looks good. Then the FLSK came along and made the world a little better: It’s cool, it’s light, it’s durable. This is the water bottle you have been waiting for.

Design meets function.

The FLSK is the first bottle of its kind, which combines the highest insulating performance with puristic design.

The FLSK makes it possible to keep drinks ice-cold for more than 24 hours and hot for 18 hours. The stylish combination of thermos and tableware turns every moment of your life into a special one: whether during sports, in everyday life, or for fine dining. The FLSK stands for contemporary drinking with style and without compromise.

FLSK Funktion

Simply innovative.

The secret of the FLSK? The innovative VICC® technology. Between the two stainless steel walls of the FLSK bottle there is a vacuum and an additional copper coating: flavor and carbon dioxide included, temperature loss excluded. 

Awarded several times.

The FLSK is more than a water bottle. The puristic design exudes charm and elegance and is a clear statement for good taste. She has already received several awards and distinctions. That does not stop us from making her even better.

You can always take her with you - in your handbag to the office or in your backpack to yoga. The FLSK accompanies you always and everywhere.

The FLSK makes your everyday life more comfortable. You need an afternoon awake or a refreshment to keep your head cool? The FLSK is here for you. She is a bit home away from home.

What exactly is the FLSK water bottle?


The FLSK thermos is an innovative stainless-steel water bottle with a high insulating capacity. Thanks to VICC® technology, it keeps drinks cold for more than 24 hours and hot for more than 18 hours. Due to the narrow opening and a very closely fitted lid, the FSLK insulating bottle is also 100% leak-proof and absolutely sealed even for carbonated drinks. And that’s not all: The FLSK is shockproof, taste-neutral, and it just looks good. This makes it an ideal water bottle for sports, work, school, or the dining table at home.
