The Black Tuff Truck Bag is a great solution if you are in the market for a black truck box because it can be used alone or in addition to an existing storage box. It’s made from weatherproof, waterproof, non-breathable PVC material and features heat fusion sealed seams along all edges. It seals tight with a heavy duty, commercial grade zipper and a waterproof PVC triple fold flap that covers the zipper. It also has heavy duty metal rings in all four bag corners in order to easily fasten the bag to the truck bed, using the included adjustable bungee cords. The Tuff Truck Bag is fully collapsible for easy storage in homes, garages or truck boxes.
