70 denier nylon ripstop fabric is a durable synthetic fabric that is perfect for outdoor usage. Because of the tightly-woven yarn construction and the addition of both PU coating and DWR treatment, it handles everything Mother Nature throws at it like a champ. It’s a terrific choice for blinds, rain flies and outdoor concealment. In addition, because it’s so light weight and packable, it is a must-have item for any backpacker or survivalist. Use it for emergency shelter, rain catching, hammocks, gear hides and so much more!
