Bobin I have noticed that and frankly I think it's just an example of economy of scale. If you really looked at the world wide clothing market I'd say we're a pretty darn tiny slice of the pie. You mentioned Sitka which seems to indeed be something on an exception (and Cabela's has several items on sale if interested) and I know Browning took a swing at it with their Transitions line though I've got no experience with it.
My "classic" hunting stuff is actually fine for stand hunting but if I'm going to be humping it much then yeah, I'll mostly be layered up like I'm headed for the ski slopes. That stuff (and what you mentioned) is made for active wear in cold weather first and foremost and it's a pretty competitive market.
