Great article, very interesting. I always felt that my old pile garments were the absolutely best for dealing with wet weather, but of course pretty heavy for the warmth, or at least for the loft compared to Polarguard or especially down. It never occurred to me to wear the pile without a base layer to improve wicking.
I would love to read similar testing of PG ( or CS or Primaloft) sleeping bags and garments, with similar shell materials, to see how much it suffered in comparison to Pertex/pile. I am assuming the pile would have a wicking advantage and be faster drying, but maybe not. The weight advantage would probably be with the PG/CS/PL. But it would be great to read a test in similar wet weather conditions, where the user got quite wet.
