This is the DOD Sotoneno Sasoi L. I purchased it new and used it 2-3 times last year for family camping. There is some slight soiling on part of the storage case due to storage, but since I used a separate sheet on top of the mat, the mat and dedicated sheet are relatively clean with no noticeable stains or marks. It can be folded compactly after use, so it can be stored in a space-saving manner. One of the inflation mat's securing straps is a third-party product. Popular model: Sotoneno Sasoi Type: Inflatable mat Features: Double size (for two people) Thickness: 5-8cm
