Hattrick, as far as not being able to try them on, the last time I was at the big sports show in Harrisburg, PA in Febuary, either SI or KOM was there with some stuff. Depending on how far a drive it is for you, it may be worth the trip just for that reason.
As far as bulking up, I picked up a GW vest this fall and fell in love with it. For most of our season I was wearing just the vest with a heave wool shirt over longjohns and was plenty warm. I used to hunt Maryland even into January and I suspect a full wool outfit may be too much for that climate. It would have been for me.
