Google "silnylon misting" for hours of fun. Much controversy re. whether water is working through the fabric or if the force of rain is knocking off condensation.
Cheers,
Oh, now that's funny! haha! The same fabric nonsensical conspiracy theories are made out of ... Behold, the hand is quicker than the eye! Belief is suspended! The mind is momentarily restrained!
Good one!
Silnylon clearly leaks under lab conditions where there is no hiker sweating and breathing inches away from the fabric and the hydrostatic column of water. In my case, it took 1200mm of water to push a given amount of water in a given amount of time through the sample to quantify the waterproofing resistance of the material.
When that water trickles from the pipe and through the fabric, I can assure you, it isn't condensation knocked off the sample by a hammering rain.
That's not to say such doesn't happen with a sweaty, humid breathed hiker, all clammy and miserable in his nightmare of a tent. But that happening doesn't preclude the dynamic pressure of rain exceeding the rating of the fabric and leaking. It's not an either/or phenomenon. I can have a leaky crack in my car's windshield,
and fog it with my breath till it runs, simultaneously.
Thanks for the heads up, Rick. I'll definitely Google that. I could use a good chuckle!
