What’s the Difference Compared to Classic Swimwear?

Most traditional swim trunks haven’t changed in decades. They come with rough mesh liners that cause irritation, fabrics that stay wet for hours, and zero support where it matters.
 

BoxHero Swim Trunks change everything.

Instead of cheap mesh, you get a built-in compression liner that feels like your favorite boxer briefs — smooth, soft, and supportive.
 

Instead of heavy, soggy fabric, you get quick-dry stretch fabric that moves with your body and dries in minutes.
 

Instead of loose pockets or none at all, you get secure zipper pockets to keep your phone, wallet, or keys safe.
 

And instead of discomfort and awkward adjustments, you get tailored comfort designed for men 40+ — so you can move freely and feel great all day.

Honestly? Best swim trunks I've ever owned.

I wore them on vacation, and they were dry before I even finished my drink. No more chafing, no more adjusting. The fabric feels premium, and after several wears and washes, they still look brand new. You can tell these are built to last.  Not too long or too short for me so sizing is perfect.

🇺🇸 These swim trunks are fire—and not just for the dudes! 

These swim trunks are fire—and not just for the dudes! The fit is perfect, the material is quick-dry, and the breathable mesh lining keeps things cool all day long. Plus, the ghost image of the American flag on the black shorts? Chef’s kiss. Whether you're at the beach, pool, or just hanging out, these trunks are a total vibe. Ladies, don’t let the “men’s” tag fool you, these look amazing on us too. You’ll feel like a beach goddess with a touch of rebellion.

John J.

Verified Buyer

They feel like gym shorts but look way better.

Supportive but not tight. Super soft. I’ve worn them every weekend since I got them.

Josh J.

Verified Buyer

Didn’t think a liner could make this much difference.

I wore them to the lake all day — no chafing, no sticking, no need to change after. They stayed comfortable from morning to evening, dried quickly, and gave me full freedom of movement. Honestly, I forgot I was even wearing swim trunks — they just felt right

Harvey M.

Verified Buyer

These look great on my husband.

These look great on my husband. I got them because he has been wearing the same old worn out swimsuit for the past 10-15 years now and it was time for a new one. The shorts seem well made, the fabric is soft yet sturdy and the pockets are actually functional, unlike many women’s swim shorts that barely hold a chapstick. The color is exactly as pictured and they are a great length for someone his height.
All-around, I’d buy them again in 10-15 years when this pair stops working haha!

Nicole N.

Verified Buyer

At my age, comfort matters — and these deliver.

Even after a full day outside in the sun, they stayed dry, and I stayed comfortable

Phil C.

Comfy, quick-dry, and they look sharp.

I wore them to the beach, then straight to lunch. No complaints — just comfort

The best trunks I’ve ever worn

I wasn’t expecting much when I bought these trunks, but man, they blew me away. The Modal fabric is ridiculously soft — feels like high-end athletic wear, not swimwear. I’ve worn them for swimming, lounging, and even running. What’s amazing is how fast they dry — no damp feeling lingering on your thighs. At my age, comfort is king. This one delivers

Mark j.

verified buyer

Got compliments from my friends too

Took these on a week-long trip to the coast, and I ended up wearing them more than any other shorts I packed. They dried in under 15 minutes after a swim, and I never felt weighed down. The inner liner fits snug without being tight, and the fabric stays breathable even in the hot sun. Got compliments from my friends too — these are my go-to now.

Finally, trunks made for grown men

I’m not the type to leave reviews, but these trunks deserve one. At 45, I care more about quality and practicality than flashiness. These deliver both. The fit is flattering without being tight, and the quick-dry claim is 100% true. I walked out of the water, sat on a towel, and within minutes I was dry. That matters more than you’d think

Tommy G.

verified buyer

Still like new after 10 washes

This swim trunk feels like it was made for grown men who still want to look sharp but feel relaxed. The support from the inner liner is solid, the pockets are well-placed, and the Modal fabric is just different — lighter, softer, and more premium than anything I’ve tried. I’ve washed it over ten times and it still feels new. Highly recommend."

Samuel p.

verified buyer

wife approves, and i love them 

The breathability of these trunks is simply exceptional. No matter what I’m doing, I always feel comfortable and fresh. Modal really does make all the difference—honestly, these are life-changing. Plus, my wife approves, and I love them!

Alex N.

Great for guys who hate typical mesh liners

You know that awful netting in most swim trunks? Gone. This one has a smooth built-in liner that actually feels good. I’ve worn these on long days by the pool and never once felt uncomfortable. No riding up, no irritation, and no heavy water-logged feeling. If you hate traditional swimwear, give these a shot.

John M.

verified buyer

Exactly what I’ve been looking for

It’s hard to find swim trunks that look good and feel good when you're over 40. These ones nailed it. The Modal fabric feels luxurious, almost like lounge shorts, and the inner liner offers the right amount of support without chafing. I’ve worn them to the beach, to the gym, and even just walking the dog. They dry incredibly fast, and I never feel sticky or sweaty. Worth every penny

Walt f.

verified buyer

Beach, and coffee runs – they do it all

These aren’t just swim trunks. They’ve basically become my everyday summer shorts. I wear them to the beach in the morning, and grab coffee without needing to change. The fabric dries so fast that you forget you were even in water. And the comfort? Unreal. Soft, breathable, and no awkward bunching like most athletic wear.

FAQ

Still have questions ? Check here

What is Modal fabric?

Modal is a premium fabric made from natural beechwood pulp. It’s softer than cotton, ultra-breathable, moisture-wicking, and resists shrinking — making it perfect for swimwear that feels like second skin.

 Can I swim in them?

Absolutely. These trunks are designed for water — pool, ocean, or lake. The Modal fabric dries quickly, stays light even when wet, and won’t cling or sag.

Do they dry fast?

Yes. Modal dries 2x faster than traditional cotton or mesh-lined swimwear. Perfect for going from swim to lounge to lunch without feeling damp or uncomfortable.

Is there a liner inside?

Yes — a built-in compression liner for support and anti-chafe comfort. No more itchy mesh or inner shorts that ride up.

Can I wear them outside the pool too?

Definitely. These 3-in-1 trunks are made for swimming, training, and relaxing. They look like athletic shorts, feel like performance gear, and move like second skin.

Will they cause chafing?

No. The smooth Modal fabric and supportive liner eliminate inner-thigh rubbing — even on hot, active days.

How do I wash them?

Machine wash cold. Tumble dry low or air dry. The Modal fabric holds its shape and softness wash after wash.
