Hmm reading the product description it has some sort of zipper opening
at the top. If the tank is strapped sideways to the rack bags and the
spout is pointing up, does the tank leak out the zipper in anyway. Seems
like that might be an issue and some reviews says it does leak.

other than a CamelBack system but I don't like to carry water on my back.
