Abstract: A mat that is convertible, when folded, into a bag. The mat includes a cushioned head portion and a larger body portion. The mat has a rectangular shape with two handle loops mounted to the cushioned head portion. A strap is attached at one end to a point on the cushioned head portion. To fold the mat, the first fold is longitudinally and the lateral edges of the cushioned head portion. The next step is to centrally fold the body portion in half thus defining the bottom for the internal cavity of the bag being formed. Next the corners of the folded body portion are folded again defining a triangle. Then, the pointed end of the triangle is brought against the cushioned head portion and the strap is passed around the folded body portion and fastened to it.
