White 420 Denier Coated Pack Cloth is a 100% nylon fabric. Its urethane coating will repel water, and it resists tearing or ripping, so it's fantastic for outdoor applications. And since it comes in this basic white, it's great for signs and banners for your bake sale announcement, grand opening, or sporting event. Or maybe you're looking for a great material to try for a bag, tote, or knapsack? Pack cloth can take a lot of abuse and keep on going, so it's perfect for heavily used items like stuff sacks or diaper bags.
