Men's Swim Shorts

About This Collection

Mariner Underwear offers a selection of 12 men's swim shorts, all made from 100% polyester and designed to dry fast after you get out of the water. Every pair includes a mesh lining, a drawstring cord at the waist, side pockets, and a rear velcro pocket. The embroidered logo finishes each style cleanly without bulk.

These are mid-length swimming shorts for men. They sit at a length that covers the top of the thigh, which is the fit most men reach for on holiday. If you want something shorter, take a look at our swim briefs.

This men's swimsuit is designed for both the beach and lounging. Neither a board short (typically longer and looser) nor a form-fitting style, it features a mid-length cut that strikes the perfect balance.

Fabric and Technical Details

The fabric is 100% polyester throughout the collection. Polyester dries quickly, holds its colour well, and doesn't cling once you're out of the water. That makes it the right choice for a day that moves between the pool, the beach bar, and the sun lounger.

The mesh lining adds comfort and support without adding weight. The drawstring lets you get the waist fit right without needing a belt or snap closure. It's a simple, functional design that holds up across a full holiday without wearing out.

Every style in the collection has been built to the same technical spec, so you're not compromising on quality when you pick a print over a plain colour or the other way around.

Colours, Prints and Design

The collection runs across navy, indigo, turquoise, coral, and red. Within those colours you'll find three directions: graphic prints with geometric patterns, stripes, and marine motifs. Clean solid colours in indigo and coral. And bicolour designs that pair navy with red.

Printed swim shorts are the most popular style for beach holidays. Men's swim shorts with a bold geometric or stripe print are easy to spot on the beach, and the designs in this range stay sharp even after repeated washing. The marine motifs fit the classic look of men's swimwear without going into novelty territory.

If you prefer something more restrained, the solid-colour styles work well for sport and training as much as for the beach. They pair with any t-shirt or beach shirt and carry over to the pool without looking out of place.

Sizes and Fit

Sizes run M, L, and XL. The fit is consistent across the collection, cut to sit at the mid-thigh and give enough room to move without excess fabric bunching around the legs when you're in the water.

If the mid-length cut isn't what you're after, Mariner Underwear also stocks swimming trunks in a shorter cut that sits higher on the leg. Both collections use the same quick-dry polyester fabric and the same pocket configuration.

Quality Without Overpaying

This collection is a straightforward way to pick up a quality pair of swim shorts for men without overpaying for the holiday season.

With 12 styles at those price points, it's easy to buy two or three different designs and rotate them across a longer trip. The fabric holds its shape and colour reliably enough to justify that.

How to Choose Your Swim Shorts

If you want a classic holiday look, the printed styles with marine motifs or geometric patterns are the obvious pick. They're the kind of swim shorts that work at the beach, the pool bar, and the resort restaurant without looking out of place.

If you're buying for sport, open-water swimming, or pool training, the solid-colour styles keep it clean and the technical fabric does the job. The mesh lining and drawstring cord hold position when you're moving, not just standing still.

For something in between, the bicolour navy and red design is a strong everyday option. It's distinctive without being loud, and the colour combination is easy to match with plain t-shirts or a beach shirt.
