Hoggle - I've never fancied the bottle-belts myself, they look cumbersome to me.
I have a basic rock'n'run 4-litre bumbag and put a 1ltr platypus in it which I just get out and drink from as and when. You can fold it up as you drain it and refill it if need be. The bumbag has compression straps which means yo can tighten down the contents and it stays snug to your back.
In a race however it can be a faff loosening the straps and twisting it round etc. Think I lost about 5 mins faffing with it during the duddon fell race that man from del monte mentions above. I did however manage to fit in 2 platypuses, 2 energy bars as well as waterproof jacket and trousers!
So the real Mccoy should be the inov8 race pro bumbag muddy mentions above which has the inbuilt bladder, but I've not used one yet, so don't know how comfy / stable it is.
Inov8 also do race pro backpacks but I think the smallest is 8 or maybe 12ltr so they are designed to hold other stuff, whereas the smallest camelback ones have less carrying space and are just designed really to hold the bladder.
