ripstop

__NOTOC__ thumb|Ripstop fabric

Ripstop is a woven fabric, often made of nylon, using a reinforcing technique that makes it more resistant to tearing and wear. During weaving, stronger (and often thicker) reinforcement yarns 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 two-dimensional structure due to the thicker yarns being interwoven in thinner cloth. Older lightweight ripstop fabrics display the thicker interlocking thread patterns in the material quite prominently, but more modern weaving techniques make the ripstop threads less obvious. A similar effect can be achieved by weaving two or three fine yarns together at smaller intervals.
