Carhartt Artic Wool socks, not sure they make them anymore, didn't see them last year, but they are the best of many I have tried. Fleece pajama pants(I prefer), or fleece "wader pants". Up top an under armor base layer and light fleece pullovers(1 or 2) as needed for warmth, with a River's West outer jacket for windproof/waterproof. Then chest waders or River's West bibs. Very lightweight, wicks moisture away, no noise. I have found nothing dryer or thinner than River's West for an outer layer. The only two problems I have had with it are (1) it doesn't breathe so you will sweat if you're active and (2) the "outer" fleece will soak up water and get heavy. That being said, when I'm active I sweat in anything, so I usually try to shed a few layers before setting dekes. And I'd rather have a heavily soaked outer layer than something that leaks at the seams and gives me a heavily soaked inner layer. The majority of the guys I hunt with/around are now making the switch. It's nice not hearing all that scraping nylon fabric in the blind as people swivel to watch for birds, and one day of hunting in the rain, when they come out soaked all the way through in other clothes, and I merely have a little moisture at the collar where it came in around my neck, well that tends to convert people.
