Sixfish Men's Swim Trunks 7-Inch

For a beach day that might include a swim, a walk along the shore, and lunch afterward, changing out of wet gear can be a hassle. Sixfish men's swim trunks combine a quick-drying outer short with a built-in compression-style liner, so they’re designed to work in and out of the water. The 7-inch length and storage details give you more to consider than a basic pair of swim shorts, especially if you like keeping small essentials close.

What matters most

The main difference is the two-layer construction. The outer shorts use 88% polyester and 12% spandex, while the breathable liner uses 92% polyester and 8% elastane. The brand describes the outer fabric as quick-drying and stretchy, and the liner is intended to add coverage and help reduce inner-thigh chafing. That may suit a long beach day better than an unlined pair, though the fit and feel of a compression-style liner are personal preferences.

Storage is another practical point: there’s a hidden phone pocket in the liner and two outer zipper pockets with drainage holes. For example, you could keep a phone close during a walk on the beach and place keys or a card in a zippered pocket while heading to the water. The listing does not establish that the phone pocket protects a device from water, so it’s best treated as a carrying pocket, not waterproof protection.

Quick sizing guide

The listed 7-inch inseam gives a useful reference for the shorts’ length, but it doesn’t tell you how the waist or liner will fit. No size chart or body measurements are provided here, compare the product’s sizing information with a pair you already like, and avoid choosing by inseam alone. Keep in mind that without that measurement, it’s hard to judge whether the liner will feel snug or relaxed on your body.

Tips for day-to-day use

After swimming, the drainage holes are intended to let water and sand escape from the outer pockets, which can help keep them from feeling as heavy. Empty those pockets before rinsing or washing the shorts, and take your phone out before getting in the water. The quick-dry fabric may be convenient when you’re moving from a swim to a casual stop, but drying time will depend on conditions, the description doesn’t give a specific time or care instructions.

These trunks are presented for swimming, surfing, sailing, kayaking, and beach activities, as well as light workouts. They’re a more feature-focused choice than plain swim shorts, with a liner and zippered storage. For someone who wants fewer layers, less pocket hardware, or a simple swim brief, that added construction may not be a benefit.

Questions before you buy

Does the liner replace underwear? The shorts include a built-in compression-style liner, but the listing does not specify whether it is intended to replace underwear. That choice comes down to your comfort and preferred fit.

Can the pockets hold small essentials? The two outer pockets have zippers and drainage holes, and the liner has a hidden phone pocket. These features provide storage, but the description doesn’t give pocket dimensions or claim that they’re waterproof.

Are these only for swimming? No. The stated uses also include beach activities, sightseeing along the shore, and light workouts, so they’re designed for more than time in the pool.

Is it worth it?

It makes sense if you want swim trunks with a built-in liner, a defined 7-inch length, and separate places for a phone and small essentials. You may want to skip it if you prefer an unlined, simpler short or need confirmed waist measurements before ordering. The key trade-off is convenience and coverage versus a more minimal feel, decide based on whether the liner and secured pockets are features you’ll actually use.
