The problem is that for some garments plastic really is just a far superior textile performance wise. I agree that microplastic pollution is a huge problem but I think a better method would be to find ways to minimize the shedding of plastics from a garment than completely banning it. Some "plastic" garments also shed MUCH more than others (basically the extra extra soft and fuzzy polyester fleece garments are the worst) while others shed very little and also need less washing as well (such as a waterproof shell)
