Ripstop fabrics are common in tough-wearing workwear and climbing gear. Often made of cotton, they are constructed using a special reinforcement technique that prevents tears and rips. During the manufacturing process thick threads are woven at regular intervals in a crosshatch pattern. The result is a fabric with an almost unbeatable strength to weight ratio that ensure small tears and snags cannot spread and ruin the garment. Because of this garments made from ripstop fabrics are extremely durable and can withstand long periods of tough wear.
