1950s Swim Trunks with Built-in Jockstraps

I remember as a child that my father had a vintage pair of 1950s? swim trunks in cotton fabric with scallop shell pattern. There was a sort of loose-looking built-in pouch, with two actual leg straps sewn in. If you go online to newspaperarchive.com, etc and type in "built-in supporter" and "Jantzen" for the summer months of the period perhaps 1949-1955, you'll get tons of hits.

In the 50s and 60s my dad wore a pair of thick, heavy wool JANTZEN Swim Trunks which, for the time were almost obscenely brief — about the same coverage as today's «boxerbrief» underwear. What I always found fascinating, considering how «revealing» the «cut», was that inside the pouch area was a PAD of thick quilted fabric with jockstrap-like legstraps which guaranteed the obliteration of any natural outline but did produce a wide low-profile «curve» in the front. The «seat», however, was contoured in a way which would certainly accentuate a shapely pair of buns. After gettiing a few sideways glances from the church ladies and some of their husbands at a Sunday School picnic, dad retired those trunks (unfortunately too large for my skinny torso) in favour of the then popular floppy shorts with a mesh «liner». Several years later, I discovered a pair of McGregor trunks which were made of a rather thick but very stretchy material similar to a wet-suit. THOSE trunks had no «modesty pad» — the pouch area was extremely «tailored» and not only FELT like a very friendly JOCK but lifted everything UP and OUT producing the best possible show of what was down there. I LOVED those trunks because I could simply slip them over my naked body and feel supported and best of all «SEXY» with that unmistakable signature bulge. All my other beachwear was uncomfortable and tawdry looking without the assistance of a good swimjock. Once my body became decently muscled I graduated to very brief and very stretchy european-style swimbriefs and only after buns fell and the spare tire became too obvious, retreated into more ample, less-revealing, trunks — but still ones with the same «friendly» pouch as the McGregor.

I’m not sure why but I find those adverts for 1930s-1950s men's swimwear extremely alluring and erotic. It might be something to do with the fact that the models so look so clean cut, wholesome and innocent - just ripe for being corrupted! A reference to a bygone era that never really existed. They’re not (trying to be) porn actors, which I find a bit of a turn off. I think it’s also something to do with all the euphemistic emphasis on “internal support”/“all day comfort” without ever mentioning penis, testicles or scrotum... It’s a sort of acknowledgement of those bits of the body that we have and know about but, oh dear, we really must never refer to them directly.

I wish there was some way to zoom in on these ads, but there isn't. At least not on my Surface tablet with Windows 11.

Thanks. The shiny speedo trunks on right probably cut off blood to your penis. Fabric like a girdle, I suspect.
I had one. Yes, girdle-like! It was a fabric called «lastex» but it stretched in only one polarized direction. I could get an attractive vertical bulge out of my white lastex suit but beware the need to splay your legs — because the lastex didnt stretch LATERALLY you then had an instant «hole» and out would pop your balls and sometimes even your dick and getting them back inside was well-nigh impossible. Those suits looked good on a stationary model, turned for the camera to catch the bulge, but as a pratical suit for active bodies they were a DISASTER....errr... well... except when the «fallout» led to particularly «erotic» action.

Vertical bulge? You mean dressing it upwards?

Well the fabric would stretch in only one direction. As ridiculous as it seems, the stretch was in the vertical direction so you had to pick a waist size VERY carefully as there was virtually no stretch — only «tightness» — to keep the damn thing from sliding down to your knees. The vertical stretch allowed your stuff to form a fairly decent bulge as long as everything stayed in place. Splaying the legs however caused a huge gap to open up in the edge of the «pouch» such as it was, and then there was nowhere for your stuff to go but DOWN and out the hole. KInd of hard to describle accurately but I remember only too well being mightily embarrased the first time it happened right in front of our beachside neighbours — two middle-aged spinsters who ran jabbering to my mother that I had «flashed» them — arrrrrgh! That was the end of «lastex» for me. Luckily it wasn't long before I discovered my absoulte favourite swim & beach attire — a beautifully stretchy pair of McGregor Trunks which had NO «liner» but a VERY stretchy and VERY «contoured» and roomy POUCH. I could slip, naked, into those trunks and feel secure and sexy, and nearly cried when they finally got so stretched-out that I had to discard them. Never found a substirtute that could hold a candle to them!

My dad's JANTZEN trunks were considerably «briefer» than those in the ads posted here. They were almost identical in «cut» to current-day low-rise «Boxer Trunk» underwear.
