JustSun men’s waterproof quick-dry swim shorts with mesh lining and phone-friendly pockets
Product description
What you’re buying and what it’s for
These JustSun men’s swim shorts are built for days where you’ll be moving between water and land. The core idea is straightforward: waterproof (so they can handle splashes and wet conditions) plus quick-drying, using a lightweight nylon fabric. Add the mesh inner lining and you’ve got a pair that’s designed to feel comfortable for long stretches, not just for a quick dip.
If you’re the sort of person who goes from swimming to a walk along the beach (or you end up training outdoors and getting sweaty), these shorts are meant to cope without feeling clunky. They’re also positioned as “beach/holiday” shorts, but the design details—pockets, adjustable waist, and the way the fabric is described—suggest they’re not only for the sea.
Key points worth considering before you buy

On paper, the standout feature is the pocket setup. There are two side pockets plus a flap back pocket, with “large space” intended for items like a phone and wallet. The brand also claims the side pockets can handle the weight of a phone without sagging, which is important if you’ve ever had swim shorts that pull down or look awkward once you’ve loaded them.
The waist is another practical element: adjustable waistband with an elastic band and drawstring. That matters because swim shorts can fit differently when wet, and an adjustable waist gives you a better chance of staying comfortable.
One limitation to keep in mind: “waterproof” and “quick-drying” are usually about handling wet conditions rather than turning the shorts into fully rainproof outerwear. If you expect heavy, prolonged water exposure, you may want to double-check what the product description implies about real-world waterproofing.
What stands out in everyday use



The mesh inner lining is there for comfort and a more “swim-ready” feel. It’s described as super soft, aiming for all-day comfort. In practical terms, that usually helps reduce the sticky, clingy feeling some people dislike when shorts get wet and then dry.
A very real use case is carrying your phone while you walk after a swim. If the pockets truly hold their shape under load, you’re less likely to end up with sagging sides or awkward shifting. Still, it’s worth being sensible with what you carry—screen weight and bulk can make any pocket system work harder, even when it’s designed for it.

Where it shines, and where it may fall a bit short
These shorts are most convincing if your priority is versatility: swimming or surfing on one part of the day, then casual walking, running, or general holiday wear later. The combination of lightweight nylon, quick-drying approach, and an inner mesh lining fits that “do-it-all day” style.
It may not be the best match if you’re after a very tailored, dressier look, because swim shorts typically prioritise function over sharp lines. It could also feel like overkill if you only ever wear shorts for dry situations (in that case, any quick-dry swim-specific pocket and lining setup may be more than you need).
Getting the size right (and the one thing not to skip)



The description asks you to read the size chart before ordering. That’s genuinely the biggest “make or break” factor with swimwear, especially with drawstrings and stated stretch (5–8 cm). Don’t assume normal shorts sizing will translate perfectly, particularly when the fabric is meant to flex and fit differently once wet.
If you’re between sizes, it can help to think about how you want them to sit when you’re active. A drawstring can fine-tune the fit, but it’s not a magic fix for major size gaps.
Should you buy it? (Final verdict)
It’s worth it if you want waterproof quick-dry swim shorts with a practical pocket setup—especially if you carry a phone or wallet and you care about pockets that don’t sag. The adjustable waistband with drawstring and mesh lining also make it a sensible pick for active days at the beach or on holiday.

You may want to skip it if you’re expecting “fully waterproof” performance in heavy rain or long-duration water immersion, or if you prefer shorts that lean more towards a smart/casual tailored style rather than swimwear function. If you’re unsure about fit, pause and check the size chart first, that’s where most buying regrets start with swim garments.
