Wild Bob 4 I looked at the item when it arrived and felt it was rather thin. The fabric also looked like it might be cold to the skin, as some similar products are. However I put it on and immediately felt a sense of warmth. It seems to be a very good inner garment to wear in the winter. It makes it much more comfortable to be in the house, I think it will lower my heating bills, since I don't feel cold all the time.
