What price range are we talking about here and how cold of weather are you planning on hunting in?

My two favorite cold weather outfits are Cabelas Revolution Fleece insulated pullover/pants and Cabelas MTO50 one piece coveralls. The former usually get pulled out when the temperature dropsbelow 35 degrees. The latter gets pulled out when the highs do not get above the teens. The Revolution Fleece combo is fairly affordable all things considered (around $220 total). The MT050 is noticeably more expensive but I found it in Cabelas Bargain Cave for about half price.
