Question: Is the water pouch removable and can you empty the water out of it?
Document: This product works well; you need to make sure that it sits in the small of your back then you don't feel any movement.I had a couple of issues with the bladder pack becoming airlocked (turned out to be a pin hole). I emailed for advice and had immediated response and replacements.For me, it holds enough water for a 13 mile run and there is room for gel packs.
There's also a side pocket for keys or a phone. It gives me the freedom of running without holding anything in my hand or carrying it on my back. I would highly recommend this to everyone.
It is the perfect length for my 5'4&#34; wife.
I have been searching for a while now for a good hydration pack. There were others with LOTS of ok reviews. I found this one , but it only had 2 reviews, but they were both  awesome reviews. It sounded like it would work, but i was a little skeptical. Man, am I so glad I bought this. Its perfect for my training runs. It really just fits in the lower back of my back, and seriously does not move.
I do like this a lot. Same suggestion as Ken, wear it in the small of your back and you barely notice it is there. No sloshing or bouncing. I emptied it during an hour and half run, but I don't think I got it quite full to capacity, and had some air space in it. I am 6' tall and only wish was the hose to be a bit longer.
Answer: no
