I liked my silpoly tarps after a few trips, mostly dry weather, so I sold the nylon. But after some decent rain this past weekend, I'm worried I jumped the gun on the poly.

First, it didn't seem the shed the water like the nylon tarps I've used for years. Second, it seemed to mist thru very fine. I've never had this with nylon but I know people mentioned it in the past, from big drops hitting hard and forcing some thru.

Here's a pic of the tarp after the rain ended and I knocked off the water as usual. I don't ever recall having this big slick of water on nylon; after a good smack the nylon usually seemed pretty dry like the bottom part of this photo, or even drier. This thing was sopped!
