Yes, you can fill carbonated drinks in the FLSK drinking bottle. The bottle is specially designed to hold the carbon dioxide and transport it safely without the liquid leaking or the carbon dioxide escaping.

The bottle isolates the heat from the water. The bottle has a normal temperature on the outside and can be carried around the office. However, I recommend the 750ml. Much more handy.

I hope this question was not meant seriously... Apart from the fact that a bottle for 6 francs was definitely produced under questionable circumstances and can hardly be any good in terms of quality, I can confirm from my own experience that the Flsk bottles are really super. They stay hot or cold for a long time and beat similar bottles from other manufacturers by hours.

The bottle is probably too high for the holder on the bike, diameter = 8.11 cm, circumference = 25.5 cm, height = approx. 32 cm.

I called FLSK and they told me it's made in China.
