Ya got me thinkin here. Smell the smoke. I like this idea somewhere I have one of those cheap 8.00 wally world camp solor showers with the hose already coming out of it. I have to find it and see what it weighs! I thought maybe my sea to summit backpacking shower might work? But the nozzle doesnt come off the bag. That water filter could double as a solar shower very nice as well. I am gonna see what I can come up with in the morning. Thanks for posting this, I like it! I hate pumping my current Katadyne filter.
