This fit as expected because I took many reviewers advice, and ordered based on the WEBSITE published sizing, rather than my normal size.  Based upon that, the size I ordered fit perfectly.  As described, it is sweatshirt material, which has a fleecy interior.  This is NOT polar fleece, so if you are looking for something as thick as that, look elsewhere.  It is comfortable, warm enough without being stifling, and still thick enough that I could answer a doorbell in it without being embarrassed.  It will also work as a swim suit cover-up if one gets chilled, and is just what I wanted.  Expect that I will wash cold, and hang to dry to avoid shrinkage, but that's normal.  Best part is, at this price, I can afford another if I need to avoid the wait to day!
