This is rather out of date at this point. Silpoly second gen is a different product the. Is discussed in this link, and fixed the seam seal issue of the first generation. Second gen also has a greater hydrostatic head the first gen.Originally Posted by bwg
From my backyard tests I am very happy with my silpoly tarp so far. Taking it out on the trail for a four day trip next week, and don't anticipate issues.
Pros of silpoly:
It's as light as silnylon.
It doesn't stretch when wet.
Easier to work with.
Increased UV resistance.
Waterproofness is about the same.
Still stretches on the bias a lot, so that it has give in windy conditions.
Polyester is more abrasion resistant, but prolly negligible considering fabric wieght.
Cons of silpoly:
Nylon is typically stronger, but considering fabric weight this is probably negligible.
Long term durability still needs to be confirmed.
I don't see any reason to use silnylon anymore, unless a long term issue comes up with the silpoly.
