Being someone who suffers from MCS, my only complaint is that when these arrived they were offgassing fumes that I could not tolerate. After washing them a few times so that I could wear them, I noticed that the pant leg itself was fine, but the offensive fume seems to originate in the elastic waist band, so perhaps some chemical component of the elastic is what I cant tolerate. I believe the company is from RI, but they were manufactured in China. I can wear them now since the elastic is around my waist, but if it were up near my face I probably still could not wear these. Other than that, I absolutely love them! The XS fits like a womens small/medium, and the medium fit my husband perfectly and hes a medium. So the size was great. I also love that they were an add-on item and were reasonably priced. Perfect light summer PJ bottoms.
