I will be getting a recumbent soon, so I was wondering how that worked with a Camelbak. Do any of the recumbents have Camelbak pockets built into the seat? I drink a lot of water, sometimes 3-4 Camelbaksful on long rides like centuries. I've got 4 Camelbaks and a couple of extra bladders so I'm set if I can just find somewhere to put the bladder(s).
