I don't really trust wool sweaters anymore. I got this great "washable wool" sweater made by Sierra Designs. It fit great, my wife thought I looked sexy in it, and it was warm. After a while, it began to get funky, and not in a good way. I washed it per the tag, and it shrank to the point that it almost came down to my navel. Disturbingly, the arms remained the same length, as did the overall fit. It went to Goodwill.
