Coyote Brown 420 Denier Coated Pack Cloth is made of urethane coated nylon. It sports a medium weight at 420 denier, which makes it easy to work with, while providing a superior durability against rips or tears. Pack cloth is resistant to moisture, too, and can repel water with ease. It's a fantastic choice when faced with any hard working end product, like book bags and knapsacks, duffel or beach bags, stuff sacks or tarps. Enjoy the wonderful texture and sheen of pack cloth in your next project.
