Leg day finally matters. If you’ve spent any time at a public pool or a beach resort lately, you’ve probably noticed something shifted. The era of the "below-the-knee" board short—that heavy, saggy relic of the early 2000s—is basically dead. It’s been replaced by a much shorter, punchier silhouette. We’re talking about short swimsuits for guys, specifically those with a 5-inch or even 4-inch inseam.
It’s about time.
For a while, men were terrified of showing thigh. It was a weird modesty thing, or maybe just a byproduct of the baggy fashion trends that dominated the 1990s. But fashion is cyclical. What was "too short" a decade ago is now the standard for anyone who wants to look like they actually know how to dress themselves. Honestly, the shift back to shorter lengths is less about being provocative and more about better proportions. If you aren't seven feet tall, wearing shorts that hit your shins makes you look shorter and stumpy. A shorter hemline elongates the leg. It just looks cleaner.
The 5-Inch Inseam Revolution
So, what changed? A lot of it comes down to brands like Chubbies and Orlebar Brown. They stopped treating men’s swimwear like an afterthought and started treating it like tailored clothing. When Chubbies launched around 2011, they leaned hard into the "Sky's Out, Thighs Out" mantra. It was tongue-in-cheek, but it tapped into a real desire for men to feel less restricted.
A 5-inch inseam is the "sweet spot" for most guys. It sits high enough to show off some quad muscle—assuming you haven't been skipping those squats—but it isn't so short that it feels like you're wearing a speedo. It’s functional. You can actually move. Have you ever tried to play beach volleyball in wet, heavy board shorts that keep catching on your knees? It’s miserable.
Why Material Matters More Than Length
It’s not just about the inches. The tech has changed. Older swimsuits were often made of heavy nylon that stayed wet for three hours after you got out of the water. Modern short swimsuits for guys usually involve a blend of recycled polyester and spandex.
Four-way stretch is the gold standard now. It means the fabric moves with you rather than resisting you. If you’re looking at higher-end options, brands like Fair Harbor or Birdwell Beach Britches are using sustainable materials—literally turning plastic water bottles into soft, quick-dry fabric. It’s wild how far the textile science has come. You can jump in the ocean, grab lunch at a boardwalk cafe twenty minutes later, and your shorts won't leave a giant wet spot on the chair.

Finding the Right Fit for Your Body Type
Not every "short" suit is created equal. If you have "chicken legs"—and hey, no judgment, some of us just have high calf insertions—going too short can sometimes emphasize that. In that case, a 6-inch or 7-inch inseam still counts as "short" by modern standards but provides a bit more coverage.
On the flip side, if you’re a shorter guy, say 5'8" or under, a 4-inch or 5-inch inseam is a total game-changer. It creates an optical illusion of height.
- The Athletic Build: You can pull off the 4-inch "vintage" look. Look for side slits; they give your thighs extra room to breathe.
- The Dad Bod: Don’t be afraid of the short length. Just make sure the waistband is comfortable. Avoid "fixed" waistbands (the ones with a fly and a button) and go for an elasticated waist with a high-quality drawstring. It’s more forgiving after a beach burger.
- The Tall & Lean: A 6-inch inseam usually looks like a 5-inch on you. Stick to that to avoid looking like you’re wearing your younger brother's clothes.
The Death of the Mesh Liner
We have to talk about the "netting." You know what I’m talking about—that scratchy, cheese-grater mesh inside cheap swimsuits that causes horrific chafing after a day in the salt water.
The best short swimsuits for guys coming out now have ditched the mesh entirely. Instead, they use "cloud liners" or compression-style shorts built inside. It feels like wearing high-performance boxer briefs. Brands like Saxx have even integrated their patented "BallPark Pouch" technology into their swim line. It’s a literal hammock for your business. Once you switch to a swimsuit with a built-in compression liner, you will never, ever go back to the mesh. It’s a one-way street.
Patterns vs. Solids: What Actually Works?
There’s a temptation to go full "Tropical Paradise" when buying swim trunks. Flamingos, pineapples, neon palm trees. They have their place. But if you want to look sophisticated, solids or micro-patterns are the move.
A solid navy, forest green, or even a dusty rose is timeless. If you do go for a pattern, keep the scale small. Massive floral prints can be overwhelming on a shorter garment. A small geometric print or a thin vertical stripe (which, again, helps with the height illusion) is usually more flattering.

Styling Beyond the Sand
The beauty of the modern short swimsuit is its versatility. Because they look more like "real" shorts and less like pajamas, you can wear them with a linen button-down or a high-quality pima cotton tee.
Throw on some leather sandals or clean white sneakers, and you're ready for a casual dinner. This "hybrid" category is booming. People want to pack less when they travel. If one pair of shorts can handle a morning swim, a hike, and a midday beer, that’s a win.
Real-World Durability
Let's be real: salt water and chlorine are brutal. They eat fabric for breakfast. If you’re buying short swimsuits for guys, check the hardware.
- Grommets: Are they brass or cheap plastic? You want rust-resistant metal.
- Drawstrings: Look for aglets (those little tips at the end) made of metal or heavy-duty dipped rubber. They won't fray in the wash.
- Pockets: A zippered back pocket is essential. There is nothing worse than losing your hotel key card or a twenty-dollar bill in the surf because your pocket didn't have a closure.
The Cultural Shift
There’s a certain confidence that comes with wearing shorter shorts. It signals that you aren't trying to hide. It’s a callback to the 1970s surf culture—think Gerry Lopez at Pipeline or those iconic photos of Paul Newman on a boat. Those guys weren't wearing shorts that covered their kneecaps. They were wearing functional, short gear that allowed them to be active.
We spent about twenty years in a weird "shame" spiral where men's clothing got bigger and baggier to compensate for some perceived lack of masculinity. That’s over. The return of the short swimsuit is really just a return to common sense.
Actionable Tips for Your Next Purchase
Stop settling for the first pair of trunks you see at a big-box retailer. If you're ready to upgrade, follow this sequence to ensure you don't end up with buyer's remorse.

First, measure your favorite pair of casual shorts. If they are 7 inches and you like them, try a 5-inch for the water. The water weight pulls shorts down slightly, so a shorter cut actually stays in place better.
Second, prioritize the liner. Reach inside the suit. If it feels like a plastic hairnet, put it back. You want something that feels like a soft jersey or a compression mesh. Your skin will thank you after the third hour at the beach.
Third, check the "dry time" reviews. Look for terms like "DWR coating" (Durable Water Repellent). This is a treatment applied to the fabric that makes water bead off. It’s the difference between being dry in 15 minutes or staying soggy for the ride home.
Finally, don't overcomplicate the color. If you’re pale, avoid bright yellows or oranges—they’ll make you look washed out. Stick to darker blues, greens, or even a classic black. If you have a tan or darker skin tone, you can pull off the neons and pastels with ease.
Investing in two high-quality pairs of short swimsuits is infinitely better than buying five cheap ones that will lose their elastic and fade in the sun by mid-July. Buy for the long haul. Your legs deserve it.
