I ordered this rug in the winter white.  It has a dark backing which shows through the thin shag.  It is very rough feeling and almost feels like plastic.  It rustles when you walk on it.  I have been very happy with Wayfair products but this one is really off.  I tried to smooth over the dark spots with my hand and it left a greasy feeling residue on my hand.  This may be the water repellant they do not tell you about in the listing.  I would never have bought a white rug that you cannot totally clean-only vacuum and spot clean.
