Rugged Made Sandbags are not only made in America, they are manufactured right here in Washington State. Designed and built by North American Tarp and Graphics in Longview, WA, these sandbags are made to last. The internal compartment is a highly-durable vinyl with a dry-bag seal that prevents any sand from escaping. The outer bag is a rugged and grippy canvas with a velcro and zipper seal that houses an internal bag.
