Walk onto any beach in Southern California or the Gold Coast right now and you’ll notice something immediately. The baggy, knee-grazing silhouettes that defined the early 2000s are basically dead. It’s a massive shift. Board shorts for men have undergone a radical transformation over the last decade, moving away from the "skater-influenced" oversized look toward technical, high-performance gear that actually stays on your hips when you take a heavy set on the head at Pipeline.
But why does this matter? If you're just grabbing a pair for a backyard pool party, maybe it doesn't. However, if you've ever dealt with "the rash"—that brutal inner-thigh chafing caused by cheap polyester and salt—you know that not all boardies are created equal.
The Surprising History of the Scalloped Hem
The board short wasn't always the high-tech garment it is today. Back in the 1950s, surfers in Hawaii were basically wearing "baggies" or modified canvas trousers. They were heavy. They didn't dry. They were honestly pretty miserable once they got wet.
Then came the 1970s. Brands like Quiksilver and Billabong started experimenting with the "scalloped" leg. Look at archival photos of guys like Wayne "Rabbit" Bartholomew. The shorts were short. We're talking 15-inch outseams. This wasn't just a fashion choice; it was about mobility. When you’re popping up on a surfboard, you don’t want fabric catching on your knees. It’s a safety hazard, really.
The 90s ruined everything. Everything got huge. We saw the rise of the "below-the-knee" board short, which was essentially a heavy cargo pant without the pockets. It took nearly twenty years for the industry to realize that dragging three pounds of wet fabric behind you isn't exactly peak performance.
What Actually Makes a Pair of Board Shorts for Men "High-End"?
Don't let the marketing jargon fool you. Most brands throw around terms like "4-way stretch" as if they invented the concept of elasticity. But there is a massive difference between a $20 pair from a big-box retailer and a $70 pair from a core surf brand like Vissla, Florence Marine X, or Outerknown.
First, let’s talk about the waistband. Traditional swim trunks have an elastic waistband with a mesh liner. Board shorts do not. If you see a mesh liner, you are looking at swim trunks, not board shorts. A true board short has a rigid, fixed waistband. This is crucial. When you dive into a wave, the water pressure wants to pull your shorts down. An elastic waist will fail you. A fixed waist with a drawstring tie (often featuring a "Lycra fly") stays put.

Fabric chemistry is where things get weird.
Most high-end shorts today use recycled polyester, often sourced from plastic bottles. Brands like Repreve have turned this into a science. But the real "secret sauce" is the DWR (Durable Water Repellent) coating. A good pair should shed water almost instantly. You should be able to walk out of the ocean, shake yourself off like a dog, and be mostly dry within fifteen minutes. If the fabric stays soggy and heavy for an hour, the DWR is either non-existent or cheaply applied.
The Problem with Seams
Seams are the enemy. In the world of board shorts for men, a seam is just a potential site for skin irritation. If you look at the top-tier models from O'Neill (like the Hyperfreak series), you'll notice they use "no-seam" technology or welded seams. Instead of stitching the fabric together, they use heat and pressure to bond it.
- It reduces weight.
- It eliminates the "thread rub" on your inner thigh.
- It allows the fabric to stretch uniformly without the thread snapping.
John Florence, perhaps the greatest surfer on the planet right now, launched his brand Florence Marine X with a focus on "triple-needle" stitching in high-stress areas but completely removing seams where they touch the skin during a paddle. It’s that kind of nuance that separates the pros from the tourists.
Length Matters: The Outseam Debate
There is a lot of confusion about how to measure board shorts. You’ll see numbers like 16", 18", 19", and 20". This refers to the outseam, not the inseam. The outseam is measured from the top of the waistband down to the bottom of the leg opening.
- 16-17 inches: This is the "retro" or "performance" fit. It sits well above the knee. It’s great for tanning your thighs and maximum movement, but it can feel a bit "short-short" for guys who aren't used to it.
- 18-19 inches: The "modern" standard. It usually hits right at the top of the knee. This is the sweet spot for 90% of men. It looks athletic without being revealing.
- 20+ inches: The "classic" or "long" fit. It covers the knee. While less popular now, it’s still preferred by some older surfers or guys with very long legs who don't want their shorts looking like hot pants.
Choosing the wrong length can throw off your entire body's proportions. If you're 5'8", a 20-inch outseam will make you look like you're wearing a skirt. Conversely, if you're 6'4", a 16-inch outseam might be a bit too much "leg" for a family BBQ.

Cinch It Up: The Closure System
Have you ever noticed the weird zigzag lacing on some shorts? That's not just for aesthetics. It’s called a "lockdown" system. Brands like Hurley (with their Phantom line) spent years perfecting a drawstring that doesn't come undone in the wash or the surf. Some even use textured laces that provide friction so the knot stays tight even when soaked in salt water.
Honestly, if your board shorts have a zipper, they’re probably more "amphibian" or "walk-shorts" than pure boardies. A metal zipper is a nightmare in the ocean—it corrodes, it’s heavy, and it’s uncomfortable when you’re laying flat on a surfboard.
The Sustainability Factor (It's Not Just Hype)
The surf industry used to be pretty dirty. Petroleum-based neoprenes and cheap plastics were the norm. But the tide has shifted. Kelly Slater’s brand, Outerknown, really pushed the envelope here with their Apex Boardshort. They are made from recycled fishing nets (Economyl) and are sewn in Fair Trade Certified factories.
Is it more expensive? Yeah, usually. But these shorts are designed to last five years, not one season. When you calculate the "cost per wear," buying one $100 pair of sustainably made board shorts is often cheaper than buying three $40 pairs that fall apart after a few trips to the beach.
Furthermore, the shift toward hemp-based fabrics is gaining steam. Hemp is naturally antimicrobial (it doesn't smell as bad if you leave it wet in your car) and it’s incredibly durable. Brands like Jungmaven and even Patagonia have been leaning into hemp blends because they feel softer against the skin than pure polyester.
Myths and Misconceptions
People think you need to wear underwear under board shorts. Stop. Please.

Wearing cotton boxers under board shorts is the fastest way to get a painful rash. Cotton holds water, stays heavy, and creates friction. If you feel "unsupported," look for board shorts that have a built-in compression liner—though most purists will tell you to just go "commando." The fabric is designed to be against your skin. If you’re worried about transparency, just don't buy white shorts made of thin fabric. Stick to darker colors or heavier weights.
Another myth: "Expensive board shorts are only for surfers."
Actually, the tech that makes them good for surfing makes them great for everything else. They are the ultimate travel short. They are lightweight, they don't wrinkle, and you can wash them in a hotel sink and they’ll be dry by morning. I’ve seen guys hike in them, gym in them, and even wear them to casual dinners in tropical climates.
How to Care for Your Gear
If you want your board shorts for men to last longer than one summer, you have to stop throwing them in the dryer. High heat destroys the elastic fibers (elastane or spandex) that give the shorts their stretch.
- Rinse with fresh water: Salt is a crystal. When it dries, those crystals act like tiny knives, cutting into the fibers of the fabric. Always rinse your shorts after a session.
- Dry in the shade: The sun’s UV rays bleach the colors and weaken the fabric. Hang them inside or in a shady spot.
- Skip the fabric softener: It clogs the "breathable" pores of the technical fabric and ruins the DWR coating.
Buying Guide: What to Look for Right Now
When you're shopping, don't just look at the print. Turn the shorts inside out. Check the seams. Are they flat? Is there a protective patch behind the fly?
If you are a "thicker" guy, look for a "scalloped" leg opening. This little V-cut at the side of the leg gives your quads more room to move without the fabric pulling tight. If you’re slim, a straight-leg cut will look much cleaner.
Real-world recommendation:
If you want the best "bang for your buck," look at the Vissla 7 Seas or the Billabong Airlite. They offer pro-level tech for under $75. If money is no object and you want the absolute pinnacle of engineering, the Outerknown Apex or the Florence Marine X F1 are the gold standards.
Final Actionable Steps for Your Next Purchase
Stop buying "swim trunks" with elastic waists if you plan on doing anything more active than sitting in a lounge chair. To get the perfect fit, follow these steps:
- Measure your actual waist: Don't go by your jean size. Denim stretches out over time; board shorts don't. Use a soft measuring tape.
- Check the "rise": If you have a longer torso, you want a standard rise. If you're shorter, a low-rise board short will prevent the waistband from sitting up near your ribs.
- Test the stretch: Grab the fabric and pull it in four directions. If it only stretches side-to-side, it’s 2-way stretch. You want 4-way stretch for any real athletic movement.
- Look for a pocket with a key loop: There is nothing worse than losing your car key or hotel card in the ocean. A zippered back pocket with an internal elastic loop is a non-negotiable for anyone who actually goes into the water.
Invest in quality, rinse them out, and keep the outseam at a respectable 18 inches. Your thighs (and your style) will thank you.
