Jockstrap:

A jockstrap (also known as a jock, strap, cup, supporter, or athletic supporter) is an undergarment for protecting the testes and penis during cycling, contact sports or other vigorous physical activity. A jockstrap 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.
Optional cups offer additional protection for contact sports and are made of hard plastic or steel, perforated for ventilation. A more flexible and comfortable soft cup is also offered for low contact sports. A flex cup variation features a hard exterior melded with a soft lining.

A similar piece of protective equipment in the sport of cricket is known as a box. In cricket, a box is usually worn by only a batsman, a wicket-keeper, and sometimes other close-up fielders. For fielders farther from the batsman, the wearing of a box would impede their movement and running (for batsmen the benefits outweigh the disadvantages).
