Don't be fooled by the words, "superior combed cotton" and" "finest combed cotton" like I was.  These sheets are 45 % polyester and 55% cotton.  For those of us who sew, we know polyester is a cheap fabric.  I just put these sheets on the bed for the first time last night and already there are snags in the fabric.  Also the fabric on the bottom side is course and shiny--must be the polyester.   I would never buy these again.
