I have looked at Sitka gear in stores. In my opinion it's primarily designed for hunting out West where you will be on the move for much of the day and will do a lot of physical exertion. I think there are better and much more affordable options for typical whitetail hunting scenarios (i.e. long treestand or ground blind sits). Sitka does make some items for cold weather stand hunting (insulated with down or primaloft), but they are ridiculously expensive and I think you would get more bang for your buck with something like Cabela's MT050. Most of the guys who get excited about the Sitka gear on Camofire are guys who live and/or hunt out West where Sitka was started. Also, the Core4Element gear that Camofire regularly sells is often said to be just as good as Sitka at a much more reasonable price.
