I think that you have to look back a few decades when...
I don't understand what is so difficult about that last plot of land. Our ancestors, hunter gatherers, would have worn leather and furs and wool. Leather and furs that are prepared using standard items such as lye and brain matter from deer to tan hides can be used to make tunics, coats, leggings and pants, as well as footwear. And wool has been around for thousands of years. You may recall some minor mentions of lambs laying down with lions, Moses as a shepherd, just to mention a couple of items. Woolen outerwear especially coats, pants, and ponchos were greatly appreciated by the cowboys, mountain men, trappers, gold miners etc. I could go on and on about these items.
If you decide to go the leather route for outer wear as opposed to the Woolrich/Hudson Bay Company solution, you will need to look into a non-petroleum solution to waterproof and protect both boots, leggins and coat. I used to recall that bee's wax may have been used at the time of the 1800s instead of whale oil, but that is a quick google I would imagine.

Frankly, both leather and pure wool outfits are expensive when purchased new. I would recommend if you have some time to place an ad in craigslist for either a hudson bay wool blanket or a set of woolrich real wool hunting outfit in red and black plaid. I am sure that there are quite a few out there getting dusty. The blankets are often stuffed into cedar chests and survive across multiple generations in that fashion. My father, now 80 something, still has his woolrich hunting suit purchased back in the 1950s I think.
You can wait for a bright sunny day, wrap your self in a full bath cotton towel, just shy of au naturel. and let us all know how that worked for you...
