Re: Wool pants
I bought a couple of army surplus wool pants that were european, probably swiss. They were only about $10 each, but worth alot more. I also have filson wool pants and bibs. The army surplus pants are not as heavy as the filson ones, but are very tough. I live near the Canadian border in Minnesota and work outside often in the winter. The wool pants provide a lot of insulation for a fabric with excellent freedom of movement. You can get warmer pants, but they will often feel more bulky. I love wool garments in snow because they handle the moisture from the snow well and dry quickly should you get a chance to go indoors. Most are dry clean only, but I have had great luck with a little woolite cold water and gentle cycle, but never dry with heat, hang or lay them flat to dry.
I say go for it if they are cheap.
