I used to use a Camelback Mule, but the pack was too short and the bladder is shaped like a hot dog.
I switched to an Osprey Synchro 10 in a m/l, it fits so much better than the Mule, the bladder is flat on the body side, and it's ventilated by being suspended away from your back. If you need to carry lots of water, it's a great way to go. Just keep it clean. That's my experience.
