At first sight was very pleased with the appearance. However, I used this for the first time last night and unfortunately I have to say that the mouth piece section reguardless if the selector for on/off leaked. I would shut the valve, bite and get the little residue out and within seconds the water would begin to dribble out.

Reliable and amazing hydration pack.
