I understand that people want different things from their sheets, sometimes depending on seasons.  These are NOT light as air, or silky-watery drape and feeling.  Rather, these are the kind of sheets that are thicker and more substantial, and rustle when you slide into them.  They are smooth and cool, decadent to slide your hand across; very well made, and totally luxurious! I have every reason to believe that they will last for many years.  Exactly what I wanted!
