Deuter is much better than Camelback for the following reasons:they are much cheaper in price while having more Quality in their make, they fit better,they have a MUCH better bite valve, they have a back panel that keeps you much drier in the heat than others called "aircomfort system", you can get one for under $60 that will carry all your stuff(including needed tools,pump,firstaid kit,a light jacket),3 liters of fluid,and your helmet too in a special bungy type holder, they have an antibacterial bladder so you can get away with not changing water if you are in the boonies, no plastic taste in the bladder,hose,or valve and the colors are better
