Outdoor Product Blue Polyethylene Tarps are a simple yet versatile piece of gear for camping, yard work, storage, construction, agriculture, boating, landscaping and emergency use. Tarps are manufactured from a woven nylon coated on both sides with high density polyethylene coating for added strength. They feature rust-proof aluminum grommets every 3 feet and on each corner for a secure tie down and hold. All four edges are heat-sealed and reinforced with PE rope in the seams. Tarps are reusable and washable.
