Thanks Lynn your succinct answer matches my question :P I guess my next question would be, is the piling a sign of serious degradation?
I did get to test these clothes out today. It was about 70 degrees most of the day and I got in a good 20 miles at German Ridge in Hoosier National Forest. It rained the early part of the day, softly at first, and then a good downpour. It then settled in to a muddy mess for the remainder.
I love the pants, save the aforementioned piling, I like the fact that they have no zipper as they are easy enough to just pull down when I have to pee. I didn't seem to sweat much with them on, they felt light and comfortable all day, rain or no rain.
I was planning on just wearing the thorofare shirt on top, but decided to wear a light cotton shirt underneath because I had heard that the material can feel a little stuffy. I guess to be fare I didn't really give it a chance, but wearing the cotton shirt and the thorofare in these conditions was too much. I did wear the shirt when it started to rain hard, and was quite impressed with how easily it shed rain, and at how quickly it dried thereafter. My cotton shirt was still wet when I got back to the car, which was nice because it kept me cool, but the thorofare shirt had dried by the time I stopped for lunch.
All in all I like the system, but will probably bring a breezy undershirt for normal hiking conditions and just add the thorofare shirt for additional warmth and rain protection. I want to thank BPL for making the look so classic, as they go great with my mountaineers hat. It's leather and not at all lightweight, but I do enjoy wearing it, it keeps the spider webs off my face, and the rain out of my eyes.
