## Description

## Key specifications

The built-in compression liner is the defining feature of these FENTENG swim trunks: it adds an inner layer of support and is intended to help keep the outer fabric from clinging to your skin when wet. The 9-inch length gives them a longer board-short profile, while the polyester-and-spandex fabric is described as quick-drying, breathable, lightweight, and stretchy in four directions.

An elastic waistband and adjustable drawstring let you change the fit at the waist. Storage comes from two side mesh pockets and a back pocket with a Velcro closure. The shorts are described as slim fit, but there’s no fabric breakdown or sizing chart information here, so the exact feel and fit are hard to gauge from the listed details alone.

## Who it’s for

These are aimed at men who want swim shorts with an integrated liner rather than a single outer layer. That setup may be useful for a walk from the beach to a casual lunch, or when moving between swimming and beach volleyball without changing into separate shorts. The stretch fabric and drawstring also suit days when you want room to move and a waist you can adjust.

It suits you if you prefer a longer swim-short shape, want an inner layer, and value pockets for small items. Not the best choice if you want an unlined suit, a looser cut, or specific information about the liner’s compression level and fabric proportions, those details aren’t provided. The listed fit is slim, so shoppers who prioritize extra room may prefer a less fitted style.

## Everyday use

The two-in-one design combines the swim short and compression-style inner brief in one garment, instead of asking you to layer separate swimwear. For example, after getting out of the water, the liner is meant to reduce the feeling of wet outer fabric sticking against your thighs. The maker also describes the material as quick-drying, but gives no drying time, so that claim doesn’t tell you exactly how quickly the shorts will be ready to wear again.

The mesh side pockets and Velcro-backed rear pocket add places for small essentials. They’re practical details for moving around the pool or beach, though the listing doesn’t specify pocket dimensions or how securely they hold items during swimming. According to the maker, the fabric is easy to clean, care instructions aren’t included in the available details.

## Practical doubts

**Does it have a built-in liner?** Yes. The shorts are described as having an inner compression-style brief intended to support the thighs and reduce sticking when wet.

**How can the waist be adjusted?** It has an elastic waistband with a drawstring, so you can tighten or loosen it. No sizing chart is included in the product details provided here.

**What pockets are included?** There are two side mesh pockets and one back pocket with a Velcro closure. The listing doesn’t say whether the pockets are designed to keep belongings secure in water.

## Final verdict

Choose these if the built-in liner is a priority and you want a longer, stretch-fabric swim short with an adjustable waist and three pockets. They offer a more integrated alternative to wearing separate swim shorts over a liner, particularly for beach days that include walking or casual activity. Skip them if you need a clearly specified compression level, detailed sizing guidance, or a relaxed cut: the available description doesn’t establish those points, and the stated fit is slim.
