Great article. I like wool and often use woolen undershirts when XC skiing or winter hiking.
One correction. The author states "or a second option equally as good is polypropylene or what was once known as polyester." Polypropylene and polyester are two quite different polymers. One is made from propene, the other from esters. They are in no way the same. They are chemically different substances.

Oops. Sorry about that. I meant to sate them as seperate, one being used before the other. Thanks.
