This is the 49' sq. outdoor blanket large enough for four people, yet able to be folded and placed into its attached 6" x 9" bag which easily fits in a backpack or beach bag. Compact enough to be left in an automobile or bag for impromptu use, the parachute-quality, rip-stop nylon is mildew resistant and dries quickly, providing ample cover for a picnic, outdoor concert, or beach outing even when placed over wet grass or sand. Built-in grommets allow the blanket to be tied or staked to the ground, and corner pockets can be filled with sand to keep it securely in place on a windy beach. Machine washable. 7' W x 7' L. (1 lb.)
