Water proof cell phone case that mounts to your vest

[vital shok]

I was reading a magazine and seen a guy who had a little cell phone pouch that was attached to his hip pack strap or vest .Not sure if it was water proof or not.I was wondering if anybody nows were to find something like that.Or if anybody has any similar things they use.It would be awesome to have something like that if I remember right it looked clear as well so you could see who was calling.I have a young daughter and everytime the phone rings I need to look to make sure nothing happened and I hate fumbling around standing in the river trying to get my phone out and what if it falls in.i have been googling it but can't find to much and info would be greatly appreciated.Also it wasn't so much a case but more like a pouch.
