Well, I don't like to dis anybody. I always assume the best of people and I want everyone to thrive and do well. Steve's description of Acrylic seems right. I was careful walking around the fire on the patio when wearing it. The description on ebay said 100% wool. I am certain that is not the case. Said "New: with tags." No tags whatsoever either on the garment or on the bag. The weight advertised was about 9% less than the postal weight with box.
