I bought one in a large, enjoyed it and wanted to go a size down and ordered a medium from the same line and it was actually larger in size than the large I had just purchased. It was also a different make, the material was different, felt and smelled different than the first one and unlike the first one, it had no marking indicating its brand (although it did indeed have a tag on the inside with "M" for medium). It was strange. Still good though, I kept both and gave one as a gift.
