....not to mention wool's superiority in keeping one comfortable under a wide range of temperatures, and even when wet; polyester has to be made in factories and requires lots of energy input; wool can be "made" by anyone with a sheep and a hand-operated spinning wheel. I recently bought a vintage wool jacket from the 70's- it's beautiful and like new. Ever see 40 year-old polyester?!
