RE: When it gets cold...
Under Armor, Scent X, 2x long sleeve t-shirts, Scent Lok Savannah light coverall, No-Scent fleece waterproof and windproof jacket. This keeps me warm down to about 25 degrees or so. If it gets colder, I wear the same, plus pack in a insulated coverall and put on and take off at the stand. I never hike with the insulated coverall on.
With all that said, today I looked at the realtree roadtrips and dream season suits.............those things are fantastic. I really wish I could get them in a more open pattern, they may be the most functional clothes I have seen yet and they are super quiet with scent blocker and water and wind proof.
