Best hydration pack!

I saw the sponsored post for Vibedration, but I thought I'd ask, what are some great hydration packs? I am looking to upgrade as mine can't really hold anything else when the water pouch is full. I'd like something that can actually hold a few items even when the pouch is full.

Bonus points if the water pouch is a separate compartment so my stuff doesn't get damp.

Bonus BONUS points if it's large enough for two water pouches in one backpack
