Lightweight and easy-to-carry beige sleeping mat. - Brand: DOD - Model Name: SOTO-SASOI M SOTONE NO MAKURA x 2 - Color: Beige - Material: Polyester - Size: M Thank you for viewing. This is a set of SOTONE NO SASOI M and two SOTONE NO MAKURA. I purchased these here. Both have been used a few times. The sheet of SOTONE NO SASOI has a slight fraying on the back. I don't think it will be a problem for use. The SOTONE NO MAKURA cover has been washed with Oxiclean. SOTONE NO SASOI M is about the size of a semi-double bed.
