Roy, I agree with you to a point. If you don't buy smart you can sink a pile of $ in exactly what you described. But, if you shop around on your quest, you can buy wool hunting clothes cheaper than the cotton or micro fibers and get the stuff you can wash. It has a lot of the oils and stuff washed out due to it being preshrunk, but it is so superior, even in that state, to the micro fibers, for keeping you warm and breathability, it is worth it.
I am a tight wad, but I have sold and traded off nearly ever piece of hunting clothes that isn't wool because of this. And I had a lot of high dollar microfiber hunting clothes.
FYI, I buy Cabelas washable wool pants, got 2 pair now I have bought when they were on sale for $39 a piece. I have a pair of columbia cao'ed pants and a pair of military surplus, which are great pants bud. I Buy cabelas washable wool button up's on sale for $39 apiece. I have 2. I own 2 of the Asbell pullover which can be hand washed. I also have 4 pair of wool socks for hunting. My next project is 2 pairs of wool long handles, and one of Teresa's wool jackets for casual wear.
Sounds like a lot but it has me covered from 60's down to 0 no problems. It really is the most versatile hunting garment material on the face of the planet. I wore them last week in the temps of the mid teens, up to 65 today. Stayed toasty warm and didn't sweat on my hikes in. But the greatest attribute of it is it does all of this with out getting stinky.
I just spent 8 days in a camp with nothing but towels baths. I wore my wool outer garmits and they smell greatt right now with no laundring. I have to change my poly propoleyne long handles and cotton undies daily, but wore the same couple pairs of wool all week. It really is the greatest.
So, if you buy smart, be patient to get deals, you get all the easy to care for wool clothing you will ever need much cheaper than the touted microfibers. And have far superior clothing to boot. Give it a try, you will not be sorry. God Bless
