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!

I've got the Jungle bag and it's great! very comfy, the bug net works well, but you've got to either get used to it being on your face/head, or buy a pair of fiberglass tent pole sections to form a half loop to keep it off your face. You can also add a liner of some type to stay warm if the temp lowers. I've used in temps ranging from 45 to 90. It's rated to 40, but you'll need to be dressed appropriately inside it for that to happen. It's a great warm weather bag. I've also used it with a piece of Tyvek for both ground cloth and tarp, along with a surplus gov't bivy sack. weighs out about 2.8 lbs total.

I think you are making some mistaken assumptions here. The problems with the tents were that they were cheap - very cheap car camping tents are frequently rated 600mm and not seam sealed, and it was mostly coming through seams.

1300mm silnylon endured a couple hours of downpour in Evolution Valley this past summer without a leak or a single drip - I have a great little Lightheart Solo tent that withstood it wonderfully. I seam sealed it before going out with it per mfr suggestion. However, in other conditions, such as last weekend on the coast (Point Reyes) where humidity was high and the ground muddy after 9 inches of rain over the past weeks, no one escaped heavy condensation inside and outside the tents - not the PU coated tents, not my tent, not the tarp. All were wet inside and out. But fortunately we know how to handle condensation.
