I'll second Rivers West. I bought the bibs last year and they are good quality, warm and quiet.

This yr I also bought the cabelas Berber fleece with windstopper pants and 1/4" pullover and it is quiet as well.

I haven't bow hunted with them, but typical movement doesn't seem noisy at all. I'd also recommend looking into icebreaker for merino wool base layers. It's expensive but they had a killer sale at the begining of the season and I stocked up on a few things.
