uncutfan saidThis is just an opinion. I think jock straps are from a different time. It used to be if you played football or basketball, every man wore a jock.
Jock straps were indeed created for a different time. The inspiration in the late 1800's was the invention of the bicycle, with a saddle that caused some men discomfort. Men's underwear at that time was loose and non-supportive, before the use of elastic spandex. The oldest jock manufacturer is Bike, named for its intended purpose.
Prior to the jock, men on horseback sometimes wore a "suspensory" that held just the balls up in a cotton pouch tied with strings around the waist, while the dick hung free. The jock soon took over the role of the suspensory.
And as athletes began to wear jocks to hold their genitals tightly in place during vigorous exercise & competition, the term "athletic supporter" became the more common term. The addition of a protective cup for contact sports ensured that the jock became common for most athletic activities, and why it remains popular in American football and among many baseball players.
Modern briefs do often eliminate the need for a jock, thanks to their elastic bindings, and sometimes elastic through the entire fabric. These were not available 50 years ago.
But I still like a jock for its formed pouch, which doesn't pull the genitals flat like most briefs do. And I also like the greater coolness of the straps, rather than a full seat.
And mostly I like a jock for its masculine look, one of the few male garments that women have not managed to appropriate for themselves.
