Waterproof, Oil and Stain Resistant: This mat features a professional composite protective layer that repels water and oil effectively. Spills like juice, soup and oil can be easily wiped clean with one swipe. It fully isolates ground moisture, preventing water seepage and dampness. Protective Surface Texture: Designed with a protective coating, this mat is denser and firmer than ordinary fabric mats. Due to its high waterproof sealing, it may feel slightly sticky on skin after long sitting. This is normal and proves its effective waterproof performance. 7-layer Composite Structure for Cloud-Like Comfort: Built with 7-layer composite technology and a soft cotton core, this blanket provides cloud-like comfort and support. It keeps you away from scratchy grass and sand outdoors, and can also serve as a yoga mat indoors. Foldable and Portable: Suitable for park picnics, beach camping, road trips and more. Easy to fold and compact when stored. Equipped with an included nylon storage bag, it can be easily placed in car storage compartments or backpacks. Oversized and Multi-Purpose: With a generous size of 80x80 inches, this mat easily accommodates multiple people. It can be used as a picnic mat, sand-proof mat, or camping blanket outdoors, and as a yoga mat or fitness mat indoors. Weight: 2.86 pounds.
