I have a design for a hammock tent and I need to make a tarp type roof from something. Cost is no object and I want water proof, but it can be non-breathable, weight is most important and I am thinking of Sil Nylon and not multiple layered product like goretex or Event. Suggestions? Is there a coated ripstop lighter vs waterproof than sil nylon? Does sil nylon really bleed through in rain?
These are my own opinions based on wisdom earned through many wrong decisions. Your mileage may vary.
