No more grass stains, soggy bottoms, or stuck-on pet hair. Rumpl park blankets are designed with durable, all-season materials like a DWR treatment to resist dirt and liquids, and an outdoor-grade exterior to prevent scratches and tears. Now you can use your park blanket on sand, rocks, and dewy grass without worrying about getting damp or dingy. And if your park blanket does get dirty, no problem. Your Rumpl is machine washable.
