RE: South Mississippi hunters...
That sounds about perfect. I use a base layer, one or two layers of fleece( depending on the temp.), and I like insulated bibs with jacket (not coveralls). That way you can walk around or walk to your stand holding your jacket and once you get in your stand and cool off, then put your jacket on to trap your core heat. I seem to sweat my b***s off when walking in with coveralls on, or trying to get dressed in my stand.
