Looking for hydration pack recommendations

Hello!

I just ran my first ever 8 mile (~12.8km) run this morning! I'm feeling pretty proud of myself because I've never run that far, but also it was a bit rough, in part, because of the heat. I felt pretty dehydrated and weak at the end of the run (with some dry heaves just for fun), and it made me realize that I'm now pushing distances where I really need to be bringing water and some easy carbs out with me.

Which running/hydration packs do ya'll recommend? Which to steer clear of? Years of running for the bus have taught me to hate running with a backpack, so I'm definitely looking for something that can tighten down and not move around.

I'm in the USA (midwest), so extra points to brands I can easily get here.

Thanks!
