A jockstrap, also a jock (male), jill (female), strap, cup, groin guard, pelvic protector (female), supporter, or athletic supporter, is an undergarment for protecting the testes and penis or vulva during contact sports or other vigorous physical activity. This article deals chiefly with the genital protective sports gear designed for the male body, colloquially known as a "jock". A jockstrap (males) consists of a waistband (usually elastic) with a support pouch for the genitalia and two elastic straps affixed to the base of the pouch and to the left and right sides of the waistband at the hip. The pouch, in some varieties, may be fitted with a pocket to hold an abdominal guard (impact resistant cup, box) to protect the testicles and the penis from injury. The jillstrap ( a "jill") is the female equivalent of the jockstrap, but is designed to protect the vulva from getting struck. Etymology The word jockstrap has purportedly been in use at least since 1891, a likely contraction of "jockey strap", as the garment was first designed for bicycle-riding messengers and deliverymen, or 'bike jockeys'. The Bike Jockey Strap was the first jockstrap manufactured in America in 1874. Jockey meaning 'rider', primarily a race horse rider, has been in use since 1670. Jockey itself is the diminutive form of the Scots nickname Jock (for John) as Jackie is for the English nickname Jack. The nicknames Jack and Jackie, Jock and Jockey have been used generically for 'man, fellow, boy, common man'. From the period c.1650–c.1850, 'jock' was used as slang for penis. The more recent American slang term 'jock', meaning an athlete, is traced to 1959 and is itself derived from 'jockstrap'. History The jockstrap was invented in 1874 by C. F. Bennett of a Chicago sporting goods company, Sharp & Smith, to provide comfort and support for bicycle jockeys working the cobblestone streets of Boston. The original incarnation of the jockstrap resembled a thong, as it featured a strap that went between the buttocks. In 1897 Bennett's newly formed Bike Web Company patented and began mass-producing the Bike Jockey Strap. The Bike Web Company later became known as the Bike Company. Bike, until 2003, was a stand-alone company. In that year, the company and its trademarks were purchased by Russell Athletic. Russell Athletic continued to produce jockstraps using the Bike brand and logos until 2017 when they retired the brand. Russell had
