Any one would work, it has a sleeve, and a place for the hose to come through. I do not use the sleeve though. Once the pack is stuffed full, it is hard to squeeze a bladder down into the sleeve. I just put it on top below the "brain" pocket.

Camelback Bladders will NOT fit inside the slots in the internal frame of this bag. at least not the medium bag. Camelback's bladder openings are round screw in's that do not fit in the tight opening to the internal frame. I just bought the Platypus Big Zip/Insulator as suggested in the answer below, and even that is a chore to get within the internal frame pocket, and i can only fill my 2 liter bladder to a liter and a half because you need the extra empty bladder space to finagle the bladder into the small frame opening. it's do-able, but frustrating, and that's without the insulator on the bladder. I have no idea how Ozzy is managing it, if we're talking about the same thing. Must be some kind of pack Houdini. or we have different versions of the pack. I'm stickin with Houdini though.

Most any bladder system will work - Camelbak, MSR etc. I personally like the Platypus Big Zip/Insulator (works great in this bag). Most of the leading hydration systems are designed to fit the slots in modern internal frame backpacks. You shouldn't have a problem with any of the leading brands.
