These are not SuPima cotton bath mats. They are 100% cotton, which is different than the SuPima Cotton. If they are SuPima, then they are not labeled correctly. They just look like a cotton towel. There is no type of backing on them at all. Not very happy with them. I am planning on returning them.
I bought reddish color because I had difficulties finding bath mats of a red color to match Christmas decorations of our bathroom. I would call them towels rather than mats. I love the color, texture and absorbing power. My only objection is the name, because when you think "mats" you expect something more thick and stiff. I covered my actual bath mats with these towels, so they don't slip on the floor, look thicker and at the same time match the color of shower curtains and decorations.
