It looks very good, but the water smells immediately and has a bitter taste, so I have to clean it. As a construction, it's amazing, but I'm afraid to use it...

Correct flask from a top company like Salomon, I will wait to see if it will collect dirt inside the mouthpiece and how I will clean it. However, no leakage from the connection or from the mouthpiece, which is top for use as I have all the flasks and vests from Salomon and it is very convenient for trail running.
After some uses with careful handling, I come back to say that a small hole opened by itself, resulting in water dripping drop by drop.
