Have you considered a camelbak? That usually what I use. There are so many vafiations and different sizes that youre sure to find one that fits you. It goes on your back like a backpack and is very comfortable and the water mouth piece is very easy to use even while running.
I use one that has back pack storage space and can expand for longer day hikes, but it also has these convinent pockets on the hip straps so you can get to quick access items like cell phones of any self defense items like mace or even a quick energy bar.
