I purchased these for my boyfriend for a trip to Costa Rica.  He is a large man (about 6'3" and 275 lbs).  He liked the pants and the way they fit.  He usually wears a 3x, but I wanted to be sure they were roomy and had enough lenght, so I ordered up one size to the 4x.  I was worried that they would look corny instead of sexy on a large man.  They looked great and he stated that they were comfortable to sleep in.  Great gift for a man who likes to wear pajamas to bed.
