I reiterate and add to my previous comments. I've experimented with polyester and wool clothing for both -76F winters in MN, and 95F weather sitting in Chicago bumper-to-bumper rush-hour traffic on an air cooled motorcycle with leather pants and jacket. As much as I prefer the wool, when in hard use, I simply can't afford to replace it every few years because of wriggling around on the concrete, tearing through branchy areas, getting paint on it, squeezing between sharp metal equipment, etc.
A BIGGER factor is that I can take the polyester clothes and toss them in the washer/dryer without worrying about anything. Muddy, greasy, paint (paint doesn't come off though), sweaty, etc. and I can just through it in with my jeans and socks. I don't know if you have many clothes you have to hand wash or hang dry, but if you are very busy it gets old really fast. Yes, some wools you can toss in the washer/dryer... but when you see some holes eat their way through your $80 wool t-shirt because of dryer 'rub' (or whatever) vs a polyester $15 workout shirt your wallet starts aching.
That being said, if you don't have a wool fleece, jacket or sweater, it is worth adding to your closet.
Yeah, after that I want to run out to buy one
