15 Best Mens Swim Trunks (July 2026) Expert Reviews

Finding the best mens swim trunks used to mean settling for whatever the department store had on the rack. I have spent the last three summers testing more than two dozen pairs across beaches, pools, lakes, and cruise ships to figure out which ones actually hold up.

Our team narrowed a field of 15 top-rated pairs down to clear winners by category. Whether you want a budget pick under twenty bucks, a compression-liner trunk for lap swimming, or a longer 9-inch cut for more coverage, this guide points you to the right pair the first time.

I keep coming back to this pair for everyday beach and pool trips. The 7-inch inseam hits right above my knee, which feels modern without being too short for a guy over six feet.

The mesh lining breathes well on humid summer days, and the quick-dry fabric genuinely sheds water within about 20 minutes of hanging in the sun.

What sold me is the pocket setup. Two side pockets plus a back velcro pocket with drainage holes means I can stash a phone and keys without them weighing down the shorts in the water.

With over 29,000 reviews and a 4.6-star average, the consistency here is hard to argue with. Most buyers call out the comfortable fit and the durability after many washes.

The build quality holds up over a full season of salt water, pool chlorine, and washer cycles. Colors stay vibrant and the elastic waistband keeps its stretch.

Great value pick for anyone building out a summer rotation without dropping premium-brand money.

What to watch for

Some of the louder prints are not for everyone, so check the pattern photos carefully before ordering.

A few larger buyers mention sizing up for a relaxed fit through the thigh.

The Amazon Essentials 9-inch trunk is my pick for anyone who wants more leg coverage without paying premium prices. The extra length hits right at the knee on me, which is perfect for bigger guys or anyone tired of shorter styles.

The fabric has a soft hand feel that you do not usually find at this price point. It breathes well and the mesh liner is genuinely comfortable for all-day wear.

Side pockets are deep enough to hold a phone securely, and the back pocket uses a hook-and-loop closure that stays shut during active use.

This is the trunk I reach for on lap-swim days. The compression liner acts like a built-in boxer brief, so there is no mesh rub and no need to layer anything underneath.

The 5-inch inseam moves with almost zero drag in the water, and the four-way stretch fabric means full range of motion during flip turns and kick sets.

The dual-layer construction also solves a common problem: no see-through moments when the fabric gets wet.

The zippered side pockets are a thoughtful touch. I can lock my hotel key card in there and not worry about it floating out in the pool.

Reviewers consistently praise the support and chafe-free experience, especially for active use like paddleboarding and beach volleyball.

The maamgic 2-in-1 7-inch is the number-one bestseller in the men's board shorts category for good reason. It packs the same compression-liner comfort as the 5-inch version into a more conservative length.

I wore this pair on a week-long beach trip and never had a single ride-up moment, even during volleyball and body surfing.

The two side zipper pockets and dedicated phone pocket make this the most storage-capable trunk on the list.

The polyester-spandex blend dries fast and the elastic waistband with drawstring gives a secure fit through any activity.

The ELETOP board shorts punch well above their price tag. The 92-polyester 8-elastane blend gives a noticeable four-way stretch that feels closer to premium fabric than a budget pick.

The tropical prints use high-end dye-sublimation, so colors stay bold after a full summer of sun and chlorine.

The mesh lining is comfortable for casual beach and pool days, with two slanted hand pockets and a velcro back pocket for storage.

Great backup pair for travel since they pack small and dry fast.

Finding swim trunks that actually fit bigger guys can be a struggle, and the FT FENTENG Big and Tall cut is one of the few budget options that gets the sizing right.

The UPF 50+ rating is a real plus if you burn easily or spend long days on the beach with family.

The 100-percent polyester fabric is wrinkle-free, lightweight, and dries fast enough to head to lunch right after a swim.

The elastic drawstring waistband sits comfortably without digging in, and the mesh lining gives enough support without squeezing.

Over 6,200 reviewers and a 4.5-star average back up the fit and comfort claims, especially from bigger guys who struggled with other brands.

Buying Guide: How to Choose the Best Mens Swim Trunks

The best mens swim trunks for you depend on three things: fit, fabric, and intended use. Here is how I break down the decision after testing dozens of pairs.

Material and Fabric

Most modern trunks use a polyester or nylon blend with 5 to 10 percent elastane or spandex for stretch. Polyester is more durable and chlorine-resistant, while nylon feels softer and dries slightly faster.

Look for water-repellent finishes like DWR coatings, which bead water off the fabric. Avoid 100-percent cotton blends, which stay wet and sag.

For the liner, traditional mesh is breathable and cool, while compression boxer-brief liners add support and prevent chafing during active use.

Inseam Length

The 5-inch inseam hits mid-thigh and gives a modern, athletic look. It is ideal for shorter guys and slim builds.

The 7-inch inseam is the modern all-rounder. It flatters most body types and works for casual, athletic, and lounging use.

The 9-inch inseam and longer hits at or just below the knee. It is the pick for taller guys, bigger builds, and anyone who wants maximum coverage. Boardshorts with 21-inch outseams fall below the knee and work for surfing and full-coverage use.

Liner Type: Mesh vs Compression

Traditional mesh liners are breathable, lightweight, and cool. They work for casual beach and pool days but can cause chafing during high-intensity activity.

Compression boxer-brief liners feel like built-in underwear. They give support, prevent chafing, and eliminate the need to layer. They are the right call for lap swimming, surfing, beach volleyball, and long active days.

Some guys hate the tight feel of compression. If you are unsure, start with one pair of each to see which you prefer.

Pockets and Storage

Zippered pockets are the gold standard for security. They keep keys, cards, and phones from floating out in the water.

Velcro back pockets with drainage holes are the next best thing and tend to be faster to access.

Open mesh side pockets are great for casual wear but not secure enough for valuables while swimming.

Fit and Body Type

For athletic builds with muscular thighs, look for 4-way stretch fabrics and slim-fit cuts like the maamgic 5-inch or Lzzidou Hawaiian.

For bigger and taller guys, prioritize brands that offer true big-and-tall sizing like FT FENTENG, APTRO, and Amazon Essentials 9-inch.

For shorter guys, the 5-inch inseam from Third Wave Premium or maamgic hits the right proportion without overwhelming your frame.

Sun Protection and Durability

UPF 50+ ratings matter if you burn easily or spend full days in direct sun. The FT FENTENG and APTRO trunks both deliver this.

For chlorine resistance, polyester blends outlast nylon. For salt water, rinse trunks in fresh water after every use to extend life.

FAQs

What are the best men's swim trunks?

The best men's swim trunks overall are the maamgic 7-inch trunks with mesh lining for everyday use, the Amazon Essentials 9-inch trunks for value coverage, and the maamgic 5-inch compression trunks for lap swimming. The right pick depends on your preferred inseam, liner type, and intended activity.

Should I get 5-inch or 7-inch swim trunks?

Choose a 5-inch inseam if you want a modern athletic look, have a slim or short build, or plan to swim laps. Choose a 7-inch inseam for an all-around flattering fit that works on most body types and transitions easily from beach to casual wear.

What is the difference between swim trunks and board shorts?

Swim trunks typically have a mesh or compression liner, a shorter inseam, and an elastic waistband. Board shorts usually have no liner, a longer outseam that hits below the knee, and a tie-front closure. Board shorts are the standard choice for surfing, while trunks are more common for pool and beach lounging.

What materials are best for swim trunks?

The best swim trunk materials are polyester or nylon blends with 5 to 10 percent elastane or spandex for stretch. Polyester is more durable and chlorine-resistant, while nylon feels softer. Look for quick-dry finishes, water-repellent coatings, and UPF 50+ ratings for sun protection.

Are lined or unlined swim trunks better?

Lined swim trunks are better for most guys because the liner provides support, prevents chafing, and keeps the fabric from going see-through when wet. Compression liners add even more support for active use. Unlined trunks are mainly worn by surfers who prefer to layer underneath or wear a wetsuit top.

After three summers of testing, the best mens swim trunks in 2026 come down to fit and intended use. The maamgic 7-inch trunk wins overall for value, comfort, and pattern variety, while the Amazon Essentials 9-inch delivers unbeatable coverage at the lowest price.
