Contain a lot of chemicals

I ordered these pants because I already have products of this brand and was previously satisfied with the convenience and quality. The product fit properly (L) But after an intensive washing was still so much chemistry in the pants contain that I got a mild skin rash with redness. I'll wash these pants now a few more times, so that the chemicals go out and I can wear the pants without any problems. The seat of your pants is excellent though and it is very convenient. The material thickness is sufficient for indoors and heated well, for there it is too thin, depending on temperature. There are two laces in his pants, which were not needed for me, because the pants already so already sat very well.
