Most beach blankets are just that-blankets. Sand and dirt get ground into their fabric, and they always seem to get wet and mildewy, which is a terrible thing when you put them in your car trunk. So, Grand Trunk designed its multi-use Parasheet Beach & Picnic Blanket with super-durable parachute nylon. It stands up to all the abuse you and your family can throw its way, and it stays tidy and funk-free for years.
