MIVEI Men's Swim Trunks, 9-Inch

Heading to the beach or getting in the water calls for shorts that can handle swimming and still carry a few small essentials. These MIVEI men's swim trunks pair a 9-inch style with pockets designed for different levels of security.

The polyester-blend fabric is described as lightweight, quick-drying, and four-way stretch. It also has a water-repellent treatment and UPF 57+ sun protection.

One detail that changes the feel: there’s no mesh liner. The elastic waist and adjustable drawstring provide the fit, so these are best for shoppers who prefer an unlined short.

Key specifications

The shorts use a polyester blend with four-way stretch and a water-repellent finish. MIVEI lists UPF 57+ protection, that may matter for time outdoors, though it doesn’t replace other sun-protection measures. The fabric is described as quick-drying, but no drying time is specified.

The waistband is elastic with an adjustable drawstring, and the design has no liner. For storage, there’s a cargo pocket with a Velcro closure and key loop, plus a zippered pocket on the opposite leg. That mix is more useful than a basic swim short with open pockets when you want to keep small items from falling out, but pockets still aren’t a substitute for a dedicated waterproof pouch.

Who it’s for

These trunks make sense for someone who wants one pair for swimming, surfing, or lounging at the beach, with enough stretch for movement and pockets for a key or cell phone. Picture walking from the sand to the water with a key secured in the cargo pocket and a phone placed in the zippered one, the separate closures give you more options than a single open pocket.

A solid pick if you prefer an unlined fit and want pockets built into your swim shorts. It might not be a great match if you rely on a mesh liner for coverage or want swimwear with a liner included. The product description also doesn’t provide a size chart or fit measurements, so choosing a size may take more care than with a listing that spells those out.

Everyday use

The no-liner construction also makes these a possible casual option beyond the water, as the product is described for gym sessions, running, and relaxing. Still, the listing gives no details about features specific to those activities, such as a dedicated athletic waistband or storage layout beyond the two leg pockets. If you mainly need running shorts, a pair designed specifically for running may be a more targeted choice.

Before you decide

Do these trunks have a liner? No. The description explicitly says they have no mesh liner.

What pockets are included? One cargo pocket has a Velcro closure and key loop, the opposite leg has a zippered pocket.

What does the description say about sun protection? It lists UPF 57+. That’s a stated feature, not a substitute for considering your overall sun protection while outdoors.

Buying verdict

Choose these if you want stretch swim trunks with an adjustable waist, no built-in liner, and a combination of cargo and zippered storage. They offer more pocket security than a plain, open-pocket swim short, while keeping the design usable for casual wear. Skip them if a mesh liner is essential, or if you need detailed fit measurements before buying. I’m assessing the listed features without having tried it, so the fit and feel in person aren’t established here.
