Jockstrap
From Wikipedia:
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. In 1897 Bennett’s newly formed Bike Web Company patented and began mass-producing the Bike Jockey Strap.
