If you like "natural" fiber, you should consider sustainably grown hemp or exclusively organic cotton. Here's an interesting link showing all the pesticides and herbicides used in growing conventional cotton (i.e. most of the cotton that folks buy).

I'm planning to soon get a jacket from the Smith Center made with a 100% hemp shell and a hemp/cotton lining. The Smith Center is a textile/clothing manufacturer dedicated to the use of sustainable materials.
