HydraPak - Ultraflask Speed V2 - Trinkflasche im Test

I took it for a test run, it was in the front pocket of my vest, and the big opening even if it doesn't move keeps stretching the body through the vest because it has an edge.
When it go to bed empty huh it was bouncing inside them little pocket in the front it's actually started leaking I guess because it was pressing on their mouthpiece. I definitely recommend something with a smaller closing even though it's more complicated to use during a run, so that it doesn't press anything.
The worst thing was when I tried to pull it out from the pocket and and I grabbed them mouthpiece it actually went off very easily which made the electrolytes spill out
