Finding swim trunks that don’t ride up, sag when wet, or turn transparent after a few wears is a surprisingly tall order. Most men settle for a pair that works “fine” — baggy 9-inch board shorts with scratchy nylon mesh or stiff cotton that stays damp for hours. The real test of a great bathing suit is whether you forget you are wearing it the second you hit the water.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent months analyzing fabric blends, liner construction, inseam lengths, pocket security, and drying times across dozens of swimwear brands to separate the designs that hold up from the ones that disappoint by mid-summer.
This guide ranks what I’ve identified as the strongest performers for 2025. Whether you prioritize a non-abrasive built-in liner, zippered security for your phone, or a quick-dry fabric that works as gym shorts, this review of the best bathing suits for men will help you buy once and stop looking.
How To Choose The Best Bathing Suits For Men
Three specs define whether a board short is a keeper or a regret: the liner type, the inseam length, and the fabric blend. Ignore any of those and you risk chafing, a poor fit, or a suit that stays wet for an hour after you exit the water.
Liner: Mesh vs Compression
Standard mesh liners create a scratchy internal layer that rubs the inside of your thighs raw after extended wear. Compression liners (spandex-nylon blends) sit flat against the skin, hold everything securely, and eliminate the need for separate underwear. Every product in this review uses a built-in liner, but the quality of that liner varies dramatically. Look for at least 12% spandex content in the lining fabric for adequate stretch and recovery.
Inseam Length and Leg Profile
Inseam measurements directly control how much leg is exposed and how the trunk behaves during swimming. 5.5-inch inseams sit high on the thigh and work best for athletic builds or men who prefer a modern, tapered look. 7-inch inseams are the sweet spot for most body types — enough coverage for modesty without looking like shorts. 9 to 10-inch inseams offer full coverage and a conservative silhouette, but can feel heavy when wet.
Fabric Blend and Drying Speed
100% polyester dries fastest but pills over time. Nylon-spandex blends (85/15 or 90/10) feel softer against the skin, stretch for better range of motion during swimming, and resist fading in chlorinated water. Avoid cotton and cotton-polyester blends — they absorb water like a towel and stay damp for 30+ minutes after you leave the water.

In‑Depth Reviews
1. Viodia Men’s Swim Trunks with Compression Liner
The Viodia trunks hit a rare trifecta: a stretchy compression liner that beats mesh hands-down, quick-dry polyester that feels soft rather than scratchy, and a 5.5-inch inseam that sits modern without being too short. Reviewers consistently note the liner holds everything secure during active swimming, and the hidden zippered pocket fits a modern phone without bulge. The fabric shows zero fading after repeated pool and ocean exposure based on long-term wear reports.
Fit runs slightly generous — the medium comfortably accommodates a 32-33 inch waist with room to breathe. The drawstring lets you fine-tune the waist, and the leg opening isn’t so narrow that it restricts thigh movement during a swim. Multiple buyers reported replacing their entire swimwear drawer with different colors of this same model, which is the strongest repeat-purchase signal a men’s swim trunk can earn.
The only trade-off is the shorter 5.5-inch length, which may feel too brief for men who prefer a conservative 7-inch or longer cut. If you want maximum leg coverage while retaining the compression liner benefit, you will need to look at the 9-inch or 10-inch alternatives in this guide. For the majority of men who want a do-everything summer short that works at the beach, pool, and gym, this is the pick.
Why it’s great
- Compression liner eliminates mesh chafing entirely
- Hidden zippered pocket fits large phones securely
- Quick-dry polyester stays comfortable out of water
- Multiple color options with consistent sizing
Good to know
- 5.5-inch inseam may feel short for conservative buyers
- Side pockets lack zippers for additional security
2. SILKWORLD Mens Swim Trunks with Compression Liner 10″
The SILKWORLD trunks deliver a 10-inch inseam that provides full coverage for taller men or those who prefer a longer silhouette, but without the baggy look that longer board shorts often suffer from. The fabric uses a soft polyester blend with noticeable stretch, and the compression liner mirrors the same supportive feel found in the Viodia — no scratchy mesh here. Reviewers at 5’11” report the 10-inch length hits just above the knee, which is ideal for swimming laps or active beach volleyball.
Elastic waistband with an internal drawstring allows micro-adjustments, and the zippered pockets (including a side pocket) keep keys and cards secure during movement. The outer fabric breathes well and dries noticeably faster than nylon-heavy alternatives. One reviewer noted the trunks worked as everyday workout shorts after swimming, thanks to the quick-dry exterior and compression liner that doesn’t bunch when walking.
Sizing runs true to waist measurement, though a few reviewers recommend ordering your normal size rather than sizing up. The 10-inch inseam does add some fabric weight when fully waterlogged, but the stretch waistband prevents sagging. If you want the longest inseam on this list with the liner upgrade, this is your option — just be aware the full coverage may feel warm in direct sun compared to a 7-inch cut.
Why it’s great
- 10-inch inseam offers maximum coverage without bagginess
- Compression liner is comfortable against skin for extended wear
- Dries quickly enough to double as gym shorts
- Zippered side pocket secures small valuables
Good to know
- Longer length adds fabric weight when wet
- Elastic waist tie may loosen with heavy use
3. Maamgic Mens Short 80s 90s Vintage 5.5″ Swim Trunks
The Maamgic trunks lean into the retro summer aesthetic with vibrant printed patterns and a shorter 5.5-inch inseam that mirrors 80s and 90s beach style. The outer shell uses a smooth, lightweight polyester that feels noticeably airy compared to heavier nylon board shorts, and the built-in compression liner (described by reviewers as comfortable boxer-brief style) eliminates the mesh irritation problem. The under-pocket (a small internal sleeve) is clever for a single credit card or key, though the side pockets lack zippers.
Size small fits a 30-33 inch waist with light compression, and the drawstring provides fine adjustment. One reviewer at 5’10” 175lbs confirmed the medium hits mid-thigh, making these a good choice for men who prefer shorter trunks without going too brief. The vintage patterns — including an orange cream color that matches the retro theme — are true to online images and resist fading after several washes.
The lack of zippered pockets means you cannot safely carry a phone while swimming laps or wading in waves. This is a trunk designed for lounging and light activity rather than sport. If security matters more than style, look at the Viodia or the budget option below. For men who prioritize a lightweight, comfortable, retro-looking swim trunk with a proper liner, the Maamgic delivers solid craftsmanship at a mid-range price point.
Why it’s great
- Lightweight polyester feels airy and non-restrictive
- Compression liner feels like comfortable boxer briefs
- Retro prints hold color after repeated washing
- Short 5.5-inch inseam suits athletic builds well
Good to know
- No zippered pockets for phone security
- Under-pocket is accessible only from inside, not ideal for quick access
4. Adoretex Men’s Guard Nylon Quick-Dry Swim Trunks 7-Inch
The Adoretex Guard trunks are built differently from the rest of this list: they use a heavy-duty nylon exterior with a traditional mesh liner rather than compression. Multiple verified lifeguards report these hold up to 8+ hour shifts in chlorinated water and frequent machine washing without fading or shrinking. The 7-inch inseam hits the sweet spot between the shorter Viodia and the longer SILKWORLD — enough coverage for professional use without looking baggy. Three pockets (two side, one back with Velcro) provide ample storage, though the back pocket lacks a zipper.
The nylon fabric is noticeably more durable than the polyester alternatives here, but it also feels stiffer out of the bag and takes slightly longer to fully dry. The mesh liner inside is standard — functional but not as comfortable against the skin long-term as the compression liners found on the other picks. The drawstring works well with the elastic waist, and the embroidered detailing adds a quality touch. Sizing runs small; order one size up if you are between sizes.
This is the only trunk in this guide that uses a mesh liner instead of compression, which is a meaningful downgrade for chafe-prone swimmers. If you need a trunk that survives daily abuse in a professional or high-frequency setting and you do not mind the mesh, the Adoretex delivers on durability. For casual beachgoers who prioritize all-day comfort, the compression-lined options above will serve you better.
Why it’s great
- Heavy-duty nylon withstands daily pool use and machine washing
- 7-inch inseam offers coverage without excess fabric
- Embroidered detailing holds up better than printed logos
- Proven durability in lifeguard and professional settings
Good to know
- Mesh liner may chafe during extended wear
- Nylon fabric dries slower than polyester alternatives
- Sizing runs small; recommend ordering one size up
5. Mens Swim Trunks with Compression Liner Zipper Cargo Pockets 9 Inch
This no-name but well-reviewed trunk competes directly with the premium options at a budget-friendly price point. It offers the same compression liner upgrade over mesh, a 9-inch inseam for full coverage, and zippered cargo pockets that secure a phone and wallet during active swimming. The outer shell uses a quick-dry polyester-nylon blend that sheds water effectively — reviewers noted it feels comfortable both in the pool and while walking around the hot springs.
Fit runs true to size according to most reviewers, with the elastic waist and drawstring providing a customizable hold. The compression liner is reported to feel supportive without digging in, which is a strong sign for a trunk at this price level. The zippered cargo pockets lay flat against the leg and do not create the dangling bulk that plagues cheaper cargo trunks. Multiple customers bought these as a replacement for more expensive suits and reported satisfaction with the build quality after several months of use.
The main compromise is that this trunk uses slightly thinner fabric than the Adoretex or Viodia, which may pill faster if worn frequently for non-swimming activities like yard work or hiking. The color selection is also narrower than the competitors. If you want a compression-lined, zippered-pocket trunk that does everything the premium options do at a lower price, this is a smart buy. Just do not expect the same fabric density after a full season of heavy use.
Why it’s great
- Compression liner at a lower price point than competitors
- Zippered cargo pockets keep phone and wallet secure
- 9-inch inseam provides conservative coverage
- Quick-dry fabric works for both swimming and casual wear
Good to know
- Fabric may pill with heavy non-swim use
- Limited color options compared to mid-range trunks

Final Thoughts: The Verdict
For most men, the bathing suits for men winner is the Viodia Men’s Swim Trunks because it combines a comfortable compression liner, a modern 5.5-inch inseam, hidden zippered pocket storage, and quick-dry polyester at a price that undercuts premium competitors without sacrificing quality. If you want full leg coverage and the same liner upgrade, grab the SILKWORLD 10-inch trunks. And for a budget-friendly trunk with compression and zippered cargo pockets, nothing beats the no-name 9-inch option.
