Near as I can make out from the September Sports Afield which someone (probably my FIL) subscribed me to, I can't kill a deer for less than $10,000 in clothes, optics, firearms, etc...
Here in the Arctic, I struggle along with some insulated bibs (read Carharts type), synthetic underwear, 40 below Hogden Pacs, fleece pants, a synthetic hoodie, and a Mouton Eskimo-built parky in the coldest weather when I'm out traveling on the snow machine. The parky is now 39 years old -the wrist wolverine trim is pretty much gone- damned campfires!
In lighter weather(read above minus 15), the Eskimo Parka is exchanged for a Cabela's goose down jacket topped by a medium wt Gore-tex insulated parka.
My answer is no- cheaper stuff- appropriately chosen and layered is all you need. The fancy stuff is ego-fluff, effective, but not necessary.
People have hunted cold/inclement weather for millenium without it.
