Swim trunks for men by SwimZip

About swim trunks

Swim trunks sit at or above knee length, with an inner mesh lining that offers support and coverage. A secure elastic waistband with drawstring adjustment keeps these swimming shorts in place during active water sports.

Unlike regular shorts, swim trunks use water-friendly fabrics that dry quickly and withstand chlorine and saltwater exposure.

The mesh interior prevents transparency when wet. Most styles include side pockets plus a back pocket with a velcro or snap closure to store small essentials.

Our stylish and functional swim trunks for men

SwimZip's men's swim trunks combine smart features for all-day comfort in the water. A performance mesh boxer liner prevents chafing and rubbing, so you stay comfortable through every beach volleyball match or pool session.

The 8-inch inseam sits at the perfect spot above your knee to provide freedom of movement for all water activities. Three drainage pockets (two at the sides and one in the back) let you store small items. Special eyelets at the back waist stop that balloon effect during water activities.

You can choose between solid colors for a classic vibe and vibrant colors that catch the eye. An adjustable waistband with a drawstring creates a secure, personalized fit.

From beach volleyball to swimming laps, our trunks excel at all classic water activities. And when you want to lounge poolside in style, these popular swim trunks keep you comfortable with their quick-dry fabric and UV protection.

Our swimwear fabric

SwimZip uses quality fabrics that perform great in water and on land. Our full-stretch fabric delivers athletic performance through advanced features and superior construction.

The lightweight material resists water absorption to keep you comfortable as you move between swimming and lounging. Our quick-drying 4-way stretch fabric wicks moisture from your skin. Regular exposure to chlorine, salt, and intense sun won't degrade these durable materials.

Every SwimZip swimsuit includes UPF 50+ sun protection built into the fibers, blocking 98% of UV rays. This protective barrier prevents premature skin aging and reduces skin cancer risk during your beach activities and water sports.

In cold conditions, our advanced fabric retains heat without compromising breathability. The rugged construction techniques resist tears and snags and extend the life of your swimwear through multiple seasons.

Why is sun protection important?

Sun protection at the beach matters because water, sand, and open spaces multiply your UV exposure. Water reflects up to 25% of UV radiation, and beach sand reflects 15% of UV rays onto your skin.

Without protection, this increased exposure leads to sunburn, sun poisoning, or long-term damage such as premature aging and skin cancer risk.

Peak hours between 10 AM and 4 PM bring the strongest UV rays. The reflection from water and sand means you can burn even under an umbrella. At the beach, UV rays hit your skin from above and below. Combine our UPF swimwear with other protection, such as sunscreen, sun hats, and shade for best results.

Men’s swim trunks FAQ

What is the difference between board shorts and swim trunks?

Swim trunks are casual swimwear for beach and pool days, with a shorter cut and built-in mesh liner. Board shorts run longer, have no compression liner, and include features for surfing and active water sports.

Read our comparison article on board shorts vs swim trunks.

Is it OK to wear swimming trunks as shorts?

Classic swimming trunks work fine as casual shorts for short periods. The mesh liner might be visible and less comfortable than regular shorts. The chlorine-resistant fabric also has a distinct look that marks them as swimwear.

Are swim trunks a good option for competitive swimming?

Swim trunks aren't good for competitive swimming. Their loose fit and mesh lining create drag in the water, slowing you down. For competitive swimming, opt for fitted racing swimwear that streamlines your movement through the water.

How can I choose the right pattern of my swim trunks?

When choosing a swim trunk pattern, start with solid designs for versatile beach-to-pool wear. Colorblock patterns add interest without overwhelming your look. If you want more personality, our delightful patterns range from subtle geometrics to bold prints. Pick patterns that match your personal style.

Is it OK to wear swimming briefs?

Swimming briefs serve a specific purpose for competitive swimming and lap swimming where speed matters. For casual beach and pool activities, most men prefer classic trunks for their greater coverage and comfort.

Can I wear everyday walk shorts instead of swim trunks?

Regular shorts aren't built for a range of water activities. Unlike classic swim trunks, everyday shorts lack quick-drying fabric and water-resistant properties. Cotton shorts become heavy when wet, take too long to dry, and may develop mildew. They also won't protect you from chlorine or salt water.

Can I wear swim trunks for surfing?

You can surf in swim trunks, but they aren't ideal for catching those perfect waves. Unlike regular athletic shorts, swim trunks might ride up or drag in the water. For serious surfing, comfortable boardshorts provide better mobility and performance with their longer length and secure waistband.
