anybody has any experience with Deuter or REI hydration packs? I know that the deuter packs dont come with hydration bladder, but I have heard good things about the overall performance of their packs. any thoughts?

I was also considering the Camelback Ventoux. enough capacity, if I need it (1500 cui) and comes with a 3L bladder.

anybody used this particular pack?

great response. thanks guys. keep them coming.
