I'm in the process of reviewing my trail equipment. one thing I would dearly love to add, is the ability of a bath/shower. I and thinking of getting the S2S ultra-sil folding water bag (not cheap, but lite! and only to hold dirty water) adding an bulkhead fitting to the bottom, that would allow either a sawyer filter or small barb hose fitting I could to attach directly. to control water flow for a bath away from the water source. anyone see projects reports, where this has been done? or just thoughts on the practicability of this?
