I love wool.
I have some surplus wool military pants of unknown manufacture that are just awesome. Completely bulletproof. I wear them skiing and hunting in the worst imaginable weather. I also use a dense wool felt beanie hat that is equally awesome.
Seriously, you have to spend some serious money to get a fabric that works better than wool, when you consider how well it breathes and how it will keep you alive even wet.
That said, now I hunt in Rivers West gear. I still ski in those wool pants though.
