Wool is nice, but not practical in all places.

The last time that I wore wool while deer hunting in Nebraska I got so many burrs stuck to it that it looked like 3-D applique camo and took several hours to pick most of them out.

I got a green/black plaid Bagle Wear jacket for Christmas 2004 and have it packed away for when I can put it to good use back in NH. When I was a kid it was a big deal when a boy got his Johnson Wool jacket in green/black or red/black plaid and Spruce Green pants before their coming of age deer season.
