Hey guys, I kind of went diy crazy last year and made a bunch of hammock prototypes. Im happy with the end result, but now I have quite a bit of breathable cloth- hexon etc - that I really have no use for. I would like to experiment making a back pack specifically to meet the needs of hammock campers. So..... is there a way to easily treat thus breathable cloth so it would be water proof and be used to make a backpack ?
