Let's be honest for a second. Most guys think of swimwear as a binary choice. You either grab a pair of board shorts that hit your knees or, if you're feeling particularly daring or European, you opt for the classic brief. That’s basically it, right? Wrong. The men’s one piece swimsuit is currently clawing its way back into the mainstream fashion conversation, and it’s doing so with a surprising amount of momentum. It’s not just a gimmick for a bachelor party or a "Borat" reference anymore. We are seeing a genuine shift toward functional, high-fashion, and performance-oriented singlets that challenge everything we thought we knew about poolside style.
Seriously, think about the history here.
In the early 20th century, a one-piece was the only thing a man would wear to the beach. Check out old photos from the 1920s. You’ll see men in tank-top style suits that covered the torso. It was about modesty, sure, but also about utility. Then, the 1930s happened. Toppers were ditched. The shirtless look became the gold standard for masculinity. We spent nearly a century thinking that showing as much skin as possible was the only way to swim. But fashion is a pendulum. It swings. And right now, it’s swinging hard back toward the "man-tank" and the wrestling-style cut.
The Real Reason You’re Seeing More One Pieces
Why now? It’s a mix of sun safety, competitive edge, and a total breakdown of traditional gender norms in clothing. Brands like Mr. Turk and Rick Owens have been playing with these silhouettes for years, but now the average guy is starting to pay attention. If you've ever spent a day at the beach and ended up with a lobster-red lower back because your shirt rode up, you already understand the practical appeal. A men’s one piece swimsuit offers seamless protection. It stays put. No more adjusting your waistband after diving into a wave.
It's also about the silhouette. A well-cut one-piece can actually be incredibly flattering. It streamlines the midsection. It elongates the legs. For guys who spend hours in the gym working on their lats and shoulders, a racerback or a deep-cut singlet frames those muscles in a way that standard trunks just can't. It’s a power move.
Performance vs. Aesthetics
We have to distinguish between the two main camps here. On one side, you have the performance gear. Think Speedo or Arena. These are technical garments. They are designed for competitive swimmers who need to reduce drag. If you look at the "Fastskin" suits used in the Olympics, they often resemble one-piece units or high-waisted jammers. They are built for speed, not for sipping a mojito.

On the flip side, you have the lifestyle suits. This is where the men’s one piece swimsuit gets interesting. These are made from heavier Lycra or ribbed fabrics. They feature bold patterns—stripes, tropical prints, or solid neon colors. They are meant to be seen. You wear these to a pool party in Vegas or a beach club in Ibiza. It’s a statement of confidence. Honestly, it takes a certain level of self-assurance to rock a tank suit when every other guy is in 7-inch inseam shorts.
Breaking Down the "Mankini" Myth
We have to talk about the elephant in the room. When most people hear "one piece" for men, they think of the neon green thong from Borat. Let’s kill that association right now. That is a costume. That is a joke.
Modern designs are much more sophisticated. Most current iterations look more like a wrestling singlet or a 1920s "union suit" than a thong. You have the "Shorty" style, which includes a short-leg bottom, and the "Tank" style, which is cut like a traditional swimsuit at the hip. These designs offer varying degrees of coverage. Some even feature zippers down the front, giving off a sporty, wetsuit-inspired vibe.
What the Experts Say
Fashion historians like Kimberly Chrisman-Campbell have often noted that men’s fashion is becoming increasingly "un-gendered." We see this on the red carpet with guys like Harry Styles or Billy Porter. Swimwear is just the latest frontier. The men’s one piece swimsuit fits perfectly into this movement. It’s about comfort and personal expression over following a rigid set of rules about what a "man" should wear at the lake.

Furthermore, from a dermatological perspective, more fabric is generally better. The Skin Cancer Foundation constantly reminds us that clothing is the first line of defense against UV rays. While a one-piece doesn’t cover your arms, it protects the vulnerable skin on your chest and back far more consistently than a dab of SPF 30 that washes off in twenty minutes.
How to Actually Pull It Off Without Looking Like a Circus Performer
If you're thinking about buying one, don't just dive in blindly. Fit is everything. Because it’s a single piece of fabric connecting your shoulders to your crotch, the "torso length" is the most critical measurement. If the suit is too short, you’re going to be in for a very uncomfortable day of "riding up." If it’s too long, the fabric will bunch at the waist and look sloppy.
- Check the fabric weight: Look for a blend of Nylon and Xtra Life Lycra. It holds its shape better against chlorine and salt.
- Pick your cut: If you’re self-conscious about your legs, go with a "legsuit" style that has a couple of inches of inseam.
- Mind the prints: Darker, solid colors (navy, forest green, black) are easier to pull off for beginners. They look like athletic gear. If you go for a wild floral print, you are leaning 100% into the fashion statement. Own it.
- Layering: You can actually wear these under a pair of unbuttoned linen pants or shorts when you're walking to the bar. It looks like a tank top. It’s versatile.
The Cultural Shift and Social Media
Instagram and TikTok have changed the game for the men’s one piece swimsuit. Influencers in the fitness and queer communities were early adopters, but it's bleeding out. You see it in high-fashion editorials. You see it on the "For You" page. People are tired of the same old look. There's a collective boredom with the standard board short.
The "retro-sport" aesthetic is also a huge driver. Everything 90s is back. Everything 70s is back. The one-piece bridges those eras. It feels vintage and futuristic at the same time. It’s weird, but it works.

A Note on Public Perception
You might get some looks. Let's be real. If you’re at a local public pool in a small town, a one-piece might turn some heads. But at a resort or a major coastal city? It’s becoming a non-issue. The "shock factor" is wearing off. We are entering an era where personal comfort and sun protection are starting to outweigh the fear of looking "different."
Choosing the Right Brand
If you're ready to shop, skip the cheap fast-fashion sites. You want something that won't go transparent the second it gets wet.
- Mr. Turk: The gold standard for stylish, bold one-pieces. They use high-quality materials and their cuts are designed for the male physique.
- Speedo: For the serious lap swimmer. Their "unisex" or male-specific singlets are built for the water, not the lounge chair.
- Double Rainbouu: Often carries edgy, printed versions that feel very "Sydney beach culture."
- Independent Etsy Makers: There is a huge market for custom-made swim singlets. This is often where you can find the best fit if you have an unusually long or short torso.
The Verdict on the One Piece
Is it for everyone? Probably not. If you’re the type of guy who just wants to blend into the background, stick to your 9-inch trunks. But if you’re active, if you’re tired of sunburns, or if you just want to try something that feels genuinely new in a world of recycled trends, the men’s one piece swimsuit is worth a look. It’s functional. It’s bold. And honestly, it’s about time men had more than two options for the water.
The move toward more inclusive and varied swimwear isn't just a flash in the pan. It's part of a broader realization that clothes don't have a gender, and comfort shouldn't be sacrificed for the sake of "tradition." Whether you're doing laps or just lounging with a book, the one-piece offers a level of security and style that is hard to beat once you get past the initial hesitation.
Your Next Steps for Diving In
- Measure your torso: Use a soft tape measure to go from the top of your shoulder, down through your legs, and back up to the same shoulder. This "loop" measurement is the only way to find a one-piece that won't pinch.
- Start with a "Shorty" cut: If you're nervous, a suit with a bit of a leg looks more like a traditional wrestling singlet or a vintage 1920s suit, which feels less "exposed" than a high-cut hip.
- Check the lining: Always ensure the suit is front-lined. This provides extra support and prevents the fabric from becoming see-through when wet, which is a common issue with cheaper polyester blends.
- Test the "Snap" test: When you try it on, pull the shoulder straps. They should snap back firmly. If they're loose, the suit will sag as soon as it absorbs water weight.
