I have worn swimmer jocks for years as underwear, but never actually swam in one until recently. I was wearing swim trunks, and have always hated the mesh liner, both the texture and the lack of support. I decided to wear a Champion swimmer jock under the trunks. It felt great; the pouch kept everything in place and I didn't have to worry about constantly adjusting myself. Made we wonder why guys stopped wearing them; maybe because most men's swimwear looks like clown pants these days. I would have preferred to swim in a Speedo or a thong, but couldn't given the venue.
