Originally made of cotton or flax, most modern webbing is made of synthetic fibers such as nylon, polypropylene or polyester. Webbing is also made from exceptionally high-strength material, such as Dyneema, and Kevlar. Webbing is both light and strong, with breaking strengths readily available in excess of 10,000 lb (44.4 kN)
