Nothing ruins a beach day or a lap session faster than swim trunks that balloon in the water, chafe your skin, or leave you feeling exposed when you dive. A proper pair needs a secure closure, a smart inseam length, and a liner that actually supports without digging in. The market is flooded with quick-dry claims and mesh-lined options that turn brittle after a few chlorinated sessions, making it harder to find a pair that feels as good on the tenth swim as it does on the first.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years breaking down the hardware and materials behind activewear, and the real difference in swim shorts comes down to the liner construction, seam reinforcement, and the fabric’s ability to shed water without weighing you down.
After analyzing the compression liners, pocket designs, and quick-dry fabrics of the top contenders, I’ve built a no-fluff guide to help you find the absolute best shorts for swimming that keep you comfortable, supported, and ready for action.
How To Choose The Best Shorts For Swimming
Ignoring the liner type is the most common mistake buyers make in this category. A cheap mesh liner can feel rough against the skin after a day in saltwater, while a quality compression liner provides gentle, chafe-free support that keeps everything in place. Beyond the liner, the inseam length determines how much leg coverage you get and whether the shorts will ride up during powerful kicks. Pockets, fabric weight, and waistband construction each play a role in how the shorts perform in and out of the water.
Inseam Length and Mobility
A 5-inch inseam offers a modern, athletic cut that gives your legs full range of motion for swimming laps or surfing. A 9-inch inseam provides more coverage and a more conservative look, making it a solid choice for board shorts or casual beachwear. Taller swimmers usually prefer a longer inseam to avoid the shorts riding up, while shorter swimmers may find the extra fabric bunches awkwardly. Match the inseam to your torso height and the level of movement you need in the water.
Liner Construction and Support
Compression liners are made from a stretchy, supportive material that replaces the need for underwear. They dry faster than traditional mesh liners and hold their shape even after repeated use in chlorine and saltwater. Mesh liners, often found on budget swim trunks, tend to become brittle, lose elasticity, and can chafe over time. A well-constructed compression liner significantly improves how the trunks feel during extended swim sessions.
Pocket Design and Security
Standard mesh pockets can balloon with trapped water and cause drag. Zippered pockets—especially those with a secure closure and a water-draining grommet—hold a hotel key, phone, or wallet without fear of it sliding out during a dive. The pocket material should dry quickly to avoid adding unnecessary weight, and the zipper should be corrosion-resistant for use in saltwater or chlorinated pools.

In‑Depth Reviews
1. Goodstoworld Mens Swim Trunks with Compression Liner 9” Inseam Quick Dry Swimsuit Shorts M-3XL
The Goodstoworld trunks hit the sweet spot between everyday comfort and durability. The 9-inch inseam sits above the knee for a no-nonsense board-shorts silhouette that stays put during laps and cannonballs. Customers consistently note the softness of the built-in compression liner, which avoids the stiffness and chafing associated with traditional mesh liners even after full days of pool and ocean use.
Reviewers highlight that the waistband doesn’t dig into the skin when cinched, and the fabric holds its structure without floating up—a common annoyance with lighter-weight swim trunks. The water drains quickly through the liner and outer material, so you’re not hauling around a soaked waistband when you step out of the water. The range of extended sizing (M-3XL) also makes it a strong choice for swimmers who struggle to find trunks that fit properly around the waist and thighs without being too long.
Fit consistency across sizes is solid, and the trunks have held up well through multiple washes, showing no fading or liner degradation. The lack of a zippered pocket is the main trade-off here, but for a mid-range price point, the overall quality and compression liner experience is tough to beat.
Why it’s great
- Soft compression liner that doesn’t irritate
- 9-inch inseam offers good coverage without riding up
- Extended sizing for a better fit
Good to know
- No zippered pocket for secure storage
- Limited color variety from some sellers
2. difficort Mens Swim Trunks Quick Dry Bathing Suit 9 inch Inseam Board Shorts with Compression Liner and Zipper Pocket
The difficort trunks are built around a compression liner that stands out for its smooth texture and supportive feel. Buyers repeatedly mention that the liner eliminates the need for additional underwear, and the 9-inch inseam offers a great middle ground for taller swimmers and those who prefer a little extra coverage. The textured fabric resists floating up and adds a tactile feel that improves grip when wet.
Practical touches like the zippered pocket set these apart from simpler board shorts. The pocket is deep enough to hold a phone securely, and the zipper stays closed even during active swimming or body surfing. Reviewers also appreciate the range of color options, noting that the dye holds well in both chlorinated pools and saltwater. The material feels soft against the skin both wet and dry, with no signs of pilling or stiffness.
One buyer who wore these every day on a Maui vacation cited them as the most comfortable pair they’ve ever owned, specifically praising the compression liner for its ability to hold up in warm, humid conditions without bunching. The only minor critique concerns long-term fade resistance in heavily chlorinated water, but the overall build quality and fit consistency remain high.
Why it’s great
- Compression liner is soft and supportive
- Zippered pocket for secure storage
- Textured fabric resists floating up
Good to know
- Some fading reported after heavy chlorinated pool use
- Fit may run slightly large for some waist sizes
3. Mens Swim Trunks with Compression Liner Zipper Cargo Pockets Bathing Suit 9 Inch Quick-Dry Swimming Shorts
This pair adds extra utility with cargo pockets that include secure zipper closures, making it a solid pick for travelers or anyone who wants to carry a wallet and phone without worrying about losing items. The 9-inch inseam aligns with the other mid-range options, and the built-in compression liner delivers the same comfort boost that buyers have come to expect from modern swim trunks. The material has a structure that won’t look faded or cheap even after several uses.
Fit consistency is a highlight here. Multiple reviewers note that these trunks fit true to size for a variety of body types, from lean swimmers to more muscular builds. The compression liner doesn’t restrict movement, and the drawstring waist provides a snug, adjustable hold without digging into the hips. The quick-dry performance is noticeable: after a 30-minute swim, the outer fabric sheds water quickly, reducing the heavy, dragging feeling.
While the cargo pockets add storage, they can cause the trunks to feel slightly heavier when wet compared to a standard side pocket. For most users, the extra utility outweighs the minor weight penalty, and the construction has held up well in both pool and hot spring environments. The primary audience for this pair is anyone who values pocket space and a versatile fit over minimalist design.
Why it’s great
- Cargo pockets with zippers for secure storage
- Compression liner is comfortable and non-restrictive
- True-to-size fit across different body types
Good to know
- Cargo pockets hold more water than side pockets
- Fewer color options compared to other models
