Jeans are trousers typically made from denim or dungaree cloth. Often the term "jeans" refers to a particular style of pants, called "blue jeans," which were invented by Jacob Davis in 1871 and patented by Davis and Levi Strauss on May 20, 1873. Originally designed for cowboys and miners, jeans became popular in the 1950s among teenagers, especially members of the greaser subculture. Jeans were a common fashion item in the 1960s Hippie subculture and they continued to be popular in the 1970s and 1980s youth subcultures of punk rock and heavy metal. Historic brands include Levi's, Lee, and Wrangler. In the 2010s, jeans remain a popular fashion item, and they come in various fits, including skinny, tapered, slim, straight, boot cut, cigarette bottom, narrow bottom, low waist, anti-fit, and flare. "Distressed" (visibly aged and worn, but still intact and functional) jean trousers have become increasingly fashionable, making pre-sale "factory distressing" a common feature in commercially sold jeans.
Jeans are now a very popular article of casual dress around the world. They come in many styles and colors. However, blue jeans are particularly identified with US culture, especially the United States Old West. As well, although jeans are mostly known as a fashion garment in the 2010s, they are still worn as protective garments by some individuals, such as cattle ranch workers and motorcycle riders, due to their high durability as compared to other common fabrics.
