If I need to carry more than 3-4 litres of water I use the
MSR Dromedary bags. They range in size from 2L to 10L. They are also all but indestructible, have lash down point on them and can easily be hung to be used as a shower or water supply. I had one fall off the rack on a down hill (my lazy self had not tied it down) it hit the road at 20mph, I walked back up the hill and retrieved it, no damage. I also like the fact it is black, I tie it on top of the rack and on a sunny day I can have a warm shower at the end of the day. If I am using it for drinking water, I will shade it somehow to keep it from getting too warm.
Nothing wrong with using the camel bak if that is what you have and it works for you. It seems to me you are carrying a bit of extra odds and ends when you could carry a 4L dromedary bag for the same amount of weight.
