It’s a sight that usually triggers one of two reactions: a smirk or a nod of respect. You know the one. For decades, the North American beach scene has been dominated by board shorts that reach the knees, essentially heavy underwater cargo pants that sag the moment they touch brine. But things are shifting. Men in swim briefs aren't just a relic of 1970s Australian lifesaving clubs or European vacations anymore. They’re showing up at local community pools, high-end resorts, and backyard BBQs. Honestly, it’s about time we stopped treating a few square inches of Lycra like a social taboo.
The "Speedo" stigma is real, but it's also kinda fading.
We’ve been conditioned to think that unless you’re an Olympic athlete like Caeleb Dressel or a retired guy in Saint-Tropez, you have no business wearing a brief. That’s just not true. Fashion is cyclical, sure, but this isn't just about trends. It’s about functionality. If you’ve ever tried to actually swim laps in baggy trunks, you know the struggle. It’s like dragging a parachute behind you.

The Engineering of the Modern Swim Brief
Modern swimwear isn't what your dad wore. Companies like Funky Trunks, Turbo, and the juggernaut Speedo have spent millions on textile science. We’re talking about PBT (Polybutylene Terephthalate) fabrics that resist chlorine degradation for hundreds of hours.
Most guys don't realize that standard nylon-elastane blends lose their shape after about twenty swims. They get "the sags." You’ve seen it—the fabric becomes translucent and hangs off the glutes. High-quality men in swim briefs use Italian-made fabrics like Carvico or Vita, which incorporate recycled plastics and offer UPF 50+ protection. These materials are designed to compress. They support the anatomy without being restrictive.
There’s a massive difference between a "racing brief" and a "leisure brief."
Racing cuts usually have a 5cm side seam. They are narrow. They are designed for one thing: reducing drag in the water. Leisure briefs, or "square cuts," often have a 7cm to 10cm side seam. They offer a bit more coverage on the hip, which honestly makes them way more approachable for the average guy who isn't rocking a 4% body fat percentage.
Why the "Dad Bod" Can Actually Pull This Off
Here’s a secret that the fashion industry doesn't talk about enough: long board shorts actually make short men look shorter. By cutting the leg line at the knee, you’re bisecting your silhouette. It’s not flattering. A swim brief elongates the leg. Even if you have a bit of a stomach—the classic "dad bod"—the vertical line created by a brief can actually balance your proportions better than a giant pair of wet, heavy shorts that pool around your ankles.
A Global Cultural Divide
If you go to a beach in Brazil, particularly Ipanema or Copacabana, the sunga is king. It’s a slightly wider version of the brief, almost a hybrid between a trunk and a bikini. In Brazil, it’s not about being "daring." It’s just what you wear. The same goes for most of the Mediterranean.
In the United States, we have this weird hang-up.
We’re okay with women wearing tiny bikinis, but the moment a man shows his thighs, it’s considered "extra." This is a relatively recent hang-up. If you look at photos from the 1950s and 60s, men’s swimwear was consistently short. Look at Sean Connery in Thunderball. He wasn't wearing board shorts. He was in a tailored, short-inseam trunk that was essentially a brief.
The shift happened in the 90s.
Grunge culture and the rise of surf brands like Quiksilver and Billabong pushed the "long and baggy" aesthetic. It became the masculine default. But we’re seeing a rebellion against that now. Gen Z and younger Millennials are increasingly opting for 5-inch or even 3-inch inseams. The swim brief is just the logical conclusion of that "shorter is better" trend.
The Practical Benefits Nobody Mentions
Let's talk about the logistics of a beach day.
- Drying time: A pair of polyester board shorts stays damp for hours. You sit in your car, and suddenly your seat is soaked. A swim brief dries in about fifteen minutes in the sun.
- Tan lines: If you care about your tan, "the farmer’s tan" on your quads is a nightmare.
- Range of motion: Whether you're playing beach volleyball or just diving into a wave, there’s no fabric catching against your knees.
- Packing: You can fit five swim briefs in the space of one pair of cargo trunks. If you’re a light traveler, this is a game-changer.
Debunking the Confidence Myth
People think you need a Greek God physique to wear a brief. You don’t. You just need to not care what people think.
Confidence is the only "accessory" that actually matters here. When you see a guy at the pool in a brief, your first thought might be "Wow, he's bold." But five minutes later, you aren't thinking about it at all. He’s just a guy swimming. The anxiety is almost entirely internal.
What to Look for When Buying
If you're thinking about making the jump, don't just buy the cheapest thing on Amazon. You’ll regret it. Cheap suits lack "modesty liners." You want a front-lined suit at the very least.
Look for brands like AussieBum, Arena, or Tyr. If you want something more "fashion" and less "I’m about to do a 400m IM," check out Orlebar Brown or Vilebrequin. They make tailored versions that feel more like clothing and less like athletic gear.
Pay attention to the drawstring. A flat drawstring is better than a round one because it won't create a weird bump under the fabric. Also, check the "rise." A low-rise brief sits below the hips, while a high-rise (more common in vintage styles) sits closer to the belly button. Most modern guys find the mid-rise to be the "Goldilocks" zone—not too skimpy, not too "retro."
The Impact of Professional Sports
We can't ignore the influence of water polo and competitive swimming. These athletes have kept the brief alive through the "dark ages" of the baggy 90s. When people see professional athletes—men who are the literal definition of peak physical performance—wearing briefs, it reinforces the idea that this is a piece of technical equipment.
But it’s also migrating into CrossFit and "hybrid" training. Many guys are using swim briefs under their workout shorts as a base layer, then ditching the shorts when they hit the pool or the sauna. It’s practical.
Making the Transition
If you’re nervous, start with a "square leg" suit.
It’s basically a very short boxer brief made of swimsuit material. It gives you the feel of a brief but keeps the silhouette a bit more familiar. Once you realize that nobody is pointing and laughing, you might find yourself gravitating toward the classic brief.
The freedom is addictive.

Once you get used to the lack of drag and the quick-drying nature of the fabric, going back to heavy board shorts feels like wearing a wet rug. It’s honestly sort of liberating to stop hiding behind yards of unnecessary fabric.
Actionable Tips for Your First Pair
- Size Up: Competitive suits are designed to be tight—like, really tight. If you’re wearing it for leisure, go one size up from your pant size so you don't feel like a sausage.
- Color Matters: Darker colors (navy, black, forest green) are much more forgiving and less "loud" than neon prints or white fabric.
- Check the Liner: Ensure it has a full front liner to avoid any "transparency issues" when you get out of the water.
- Own the Look: Walk with your shoulders back. If you look like you’re trying to hide, people will notice. If you act like it’s the most natural thing in the world, it becomes exactly that.
The era of the "shameful" swim brief is ending. Whether it's for the better tan, the faster swim, or just the fact that you're tired of carrying two pounds of water in your pockets, the brief is a tool of efficiency. It’s a classic piece of menswear that is finally being reclaimed by the average guy.
Next Steps for the Transition:
- Measure your waist at the point where you actually want the suit to sit (usually lower than your jeans).
- Research PBT fabrics if you plan on using the suit in chlorinated pools to ensure it lasts more than one season.
- Start with a dark navy square-cut to bridge the gap between traditional trunks and a full racing brief.
