I’m in the USA and swim briefs have always been a fashion no-no here. Go to a beach and you almost rarely see anyone in a swim brief. And go to a department store here as well and all you will see in the swim section are swim trunks; no briefs. The only way to buy them is online. BUT in my fitness club where I swim, 90% of the guys here that swim are swimming in briefs! I was actually very surprised to see it when I first joined the club and I honestly thought I was going to be the only one wearing briefs, but nope. Most of the men here wear briefs, which shocked me!
So for those of you that live in an area where swim briefs are not the fashion, do a lot of men wear briefs where you swim?
It’s fitness, the intention is different. Have you seen what cyclist wear compared to someone casually biking. When you’re going to beach you’re likely doing things other than swimming too
