I ordered this set of sheets based on the information listed. Unfortunately it did NOT include that these sheets are single ply Pima Cotton. Don't be fooled. These sheets are soft, but they aren't THAT soft, and they are soooo thin, they won't last as long as other 400 TC sheets do. These sheets wrinkle BADLY. No only in the drier, but on the bed too. The good part is they are without a doubt, the deepest pocket sheets on the market (at this price anyway.) A big disappointment and not the quality I have come to expect from Overstock.
