Jockstrap

This character wears a jockstrap.

It is an undergarment for supporting the male genitalia 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. Some jockstraps have cups that offer protection.
