Product description
The essentials
If you want swim shorts that do more than just look the part, these JustSun men’s swim shorts are built around two practical ideas: they dry quickly, and they try to keep your essentials secure while you’re out in and around the water. On paper, that’s a sensible combination for the sort of days where you’ll go from beach to a quick dip to a walk or a bit of surfing.
They’re described as waterproof and quick-drying, made from lightweight nylon, and lined with a mesh interior for a more comfortable feel. The waist is adjustable with an elastic band and drawstring, and the pockets are a big part of the design—especially the side pockets meant to handle the weight of a phone without sagging.
What you’ll notice in everyday use

The most convincing selling point here is the pocket layout. You get two side pockets and one flap back pocket, with enough room “for your phone, wallet ect.” The key detail is the claim that the side pockets can “easily bear the weight of the phone without sagging”. That’s exactly the kind of thing you notice when you’re in and out of the water or walking around—if the pocket stretches or sags, it turns annoying fast.
The other noticeable factor is the mesh inner lining. The product description calls it super soft and aimed at all-day comfort. It’s a small feature, but it tends to make a difference when shorts get damp and you’re moving around for hours.
One limitation to keep in mind: the shorts are marketed as waterproof, but waterproof swimwear can mean different things in practice. It’s worth treating this as “water-resistant / designed to handle splashes and swimming” rather than assuming they’ll behave like fully sealed technical gear.


Key points on performance and comfort

These JustSun swim shorts are positioned as versatile beach and outdoor swimwear. They’re described as suitable for swimming, surfing, walking, running, casual wear, and holiday beach activities. The drawstring waist with a 5–8 cm stretch (as stated) should help with day-to-day fit adjustments, too.
If your main goal is comfortable movement with quick drying and storage that doesn’t flop around, the design fits that brief. If you need something more specialised—for example, very long-distance swim training or gear that’s guaranteed to stay perfectly dry in heavy, extended soaking—you may find this sits more in the “reliable everyday” bracket than the “serious technical kit” bracket.

Who it suits (and who should be cautious)
It makes sense if you want swim shorts that can handle a phone and wallet, dry quickly after getting wet, and feel comfortable thanks to a mesh lining. They’re also a reasonable choice if you prefer an adjustable waistband rather than relying on fixed sizing.


You may want to skip them if you’re very picky about exact fit and you’re not willing to check the size chart first—this is specifically something the listing asks you to do. Also, if you’re expecting “waterproof” to mean no water ingress at all under prolonged immersion, it might disappoint.
Getting the most from them

Start by checking the size chart before ordering. The listing explicitly encourages this, and with swim shorts the difference between a good fit and an annoying one is mostly in the waist and pocket movement. Once you’re wearing them, you’ll likely appreciate the drawstring/elastic combo for tightening as conditions change—walking on sand, getting in the sea, then moving around again.
Mini FAQ
Are these JustSun shorts really quick-drying?
They’re described as quick-drying and made from lightweight nylon. That’s the general profile you’d expect for swim shorts designed to dry faster than cotton-style fabrics.

Will a phone fit comfortably in the pockets?


The description says the side pockets have large space for your phone and wallet, and that they can handle the weight of a phone without sagging. If carrying your mobile is a deal-breaker, this pocket-focused design is the reason to consider them.
Is the inner lining comfortable when the shorts get wet?
The mesh inner lining is described as super soft and aimed at all-day comfort, which should help with the “clammy” feeling you can get with some swimwear.

Can I use them beyond the beach?
Yes—according to the listing they’re suitable for swimming, surfing, walking, running, casual wear, and holiday beach activities.
Should you buy it?
Buy these JustSun men’s waterproof quick-dry swim shorts if you value practical storage (especially phone-friendly side pockets), an adjustable waistband, and a mesh lining for comfort when your shorts are wet. They’re designed for everyday beach and water activities where you want minimal faff: wear, move, rinse off, and keep going.
Don’t buy them if you’re expecting fully sealed technical “no water ingress” performance, or if you usually ignore size charts and just hope for the best. In that case, you may end up wrestling with fit more than you’d like—because the listing makes the sizing check part of the deal.
