Yep. Just for fun, I searched for "wool shirt", clicked the first result, opened the first men's shirt I found[1], and checked the fabric: 38% Montana Merino Wool, 50% American Polyester, 12% Modal (beech wood pulp). Half plastic, when I searched specifically for wool.

I remember when fleece and microfiber fabrics (made out of recycled plastic bottles) were introduced and loved because it "kept plastic out of the waste stream." Nobody thought ahead to "those cheap blankets and jackets are going to be thrown away too" (I've never seen fleece fabric accepted for recycling) and "they shed microfibers every time you wash them."

Cotton production uses immense amounts of water. It may not contain plastic micro-beads, but it is a eco-disaster.

It is not? I prefer to avoid plastic in general, so most clothes I buy are 100% cotton. If I wanted to, I could also go with organic cotton instead, it’s almost always an option for online clothing stores (less so for the metal band shirts which I wear 99% of the time).
