Army Surplus for my pants... (Although it has been a couple years). Durable, quiet, comfortable, and affordable.
Camo shirt, with fleece over the top. Have some Heavy fleece tops if it is really cold that are quiet.
If it it wet, anything that keeps you dry does tend to be more noisy. I have some bibs with fleece-like coating that does stay dry, and are quiet, but they are also heavy and cumbersome to wear.
Granted I am hunting in California, and for the most part, low temps are in the 40's (which is unusual for turkey hunting) and high temps have been in the 90's on some years (in the afternoon).
