Ripstop fabrics are woven farics often made out of nylon, using a special reinforcing technique that makes them resistant to tearing and ripping. During weaving (thick) reinforcement threads are interwoven at regular intervals in a crosshatch pattern. The intervals are typically 5 to 8 millimeters (0.2 to 0.3 in). Thin and lightweight ripstop fabrics have a 3-dimensional structure due to the thicker threads being interwoven in thinner cloth. but more modern weaving techniques make the ripstop threads less obvious.
Ripstop fabric, sometimes called a sports fabric, is a woven, lightweight, nylon-threaded material that resists tearing and ripping. Ripstop fabric can be water resistant and is commonly used for camping equipment such as tents and the outer shells of sleeping bags. It is also used to make hang glider and parasail wings, parachutes, hot air ballons, sails, kites, flags, banners and sports clothes. The tough beating ripstop fabric can take makes it ideal for any application that requires material that won't fail under stress.
