Swim Jock question

[Dooley67]

I used to wear a swim jock many years ago, like 35 years ago, when I occasionally wore swim shorts that look like today's board shorts. The jock was much more narrow than a regular jock with a very narrow waistband. The shorts were unlined and needed a swim jock just like today's boarders need a speedo underneath them. But then again, today, why wear a speedo underneath board shorts, just wear the speedo!

I don't think they are marketed any more. They were of course minimal in all parts in order not to show beyond the outline of your swimming trunks and so what benefit they were for support and/or modesty I never quite understood.
