Father-son matching swim trunks with UPF 50+ sun protection

Swim trunks for father and son

Our boys’ and men's swimming trunks are comfortable, convenient, and sun-safe. A tailored fit and super soft liner keep you comfortable all day, while the quick-dry fabric has you ready for your next swim in no time.

Three pockets let you carry essentials or collect seashells, but strategically placed eyelets keep you from carrying water. And the ultra-soft jersey shorts liner prevents chafing, so you can fully enjoy your day.

An elastic waistband and adjustable drawstring provide a flexible fit, and these men's swim trunks have 8 to 8.5-inch inseams depending on size. Eyelets at the center back waist and pocket prevent air buildup during cannonballs for ease of movement.

Your son's swim trunks feature the same playful patterns and bright colors as yours. The comfortable mesh liner and secure fit handle everything from wave jumping to beach games without worry.

European swim trunks for streamlined style

These shorter-length swim shorts contour the body for no-snag, streamlined water activities. The side pocket keeps valuables secure, while the adjustable drawstring provides a comfortable all-day fit. The full lining and 4-way stretch of our Euro shorties let you move freely, whether you're building sandcastles or catching waves with your boy.

Rash guard sets for maximum coverage

Protect yourself and your son from harmful UV rays with our matching rash guard sets. Choose from men's rash guards and boys' rash guards in coordinated patterns. Each set includes a protective top with our signature full-front zipper and coordinating swim bottoms built for non-stop beach action.

The rash guard's protective neck collar shields sensitive skin, while chin-saving zipper guards prevent that annoying metal-on-skin contact during active play. Made with stretchy materials that bounce back to their original shape, these sets handle everything from body surfing to beach volleyball.

High-visibility options for safety

Our neon swimwear collection makes it easy to spot your little one in crowded pools and busy beaches. Bright colors, like neon green, orange, and pink, create eye-catching father-son combinations that keep you both sun-safe and add a bright layer of water safety to your beach day.

Our swimwear fabric

SwimZip's performance fabrics handle whatever your beach adventures throw at them. Our moisture-wicking materials pull water away from your skin to keep you comfortable, whether you're catching waves or lounging under an umbrella. Tough fabrics resist damage from chlorine, salt water, and all-day sun exposure.

Our UPF 50+ technology blocks 98% of harmful sunlight. This invisible shield protects your skin from UVA and UVB rays, reducing your risk of sunburn, premature aging, and skin cancer. Superior UV protection is how we earned the Skin Cancer Foundation's Seal of Recommendation, so you know you’re putting on sun protection you can trust.

Four-way-stretch materials move with every reach, twist, and swimming stroke. The fabric flexes and bounces back without losing shape, so you won't spend your time constantly adjusting and tugging. On chilly morning swims and breezy beach days, our breathable fabric traps a thin layer of water against your skin for added warmth.

Sizing and fit

Our sizes range from infants through teens and adults. Check our size chart for detailed waist and hip measurements, as well as instructions for finding the right fit.

Why is sun protection important?

Your skin soaks up UV radiation every time you step outside. Too much exposure leads to premature aging, dark spots, sun poisoning, and increased skin cancer risk. Kids need extra defense since their sensitive skin absorbs UV rays more easily than adult skin.

The sun emits two types of UV rays:

UVA rays that penetrate deep into skin layers
UVB rays that trigger sunburns and surface damage.

Both types increase your skin cancer risk. Our protective fabric technology blocks 98% of UV radiation. Skin Cancer Foundation-approved swimwear gives you confidence during extended sun exposure. Pair your UPF swimwear with sunscreen for complete freedom to enjoy sunny days safely.

Father-son swimwear FAQ

What's the difference between a compression liner and a mesh lining?

Compression liners are like synthetic boxer briefs. They fit tight, provide extra support, and reduce chafing during extended water activities. Mesh lining fits loosely and is porous. It offers lighter coverage and faster drying times. Both options maintain comfort during active beach days, so choose based on your preference for support level.

Are matching swim trunks good gifts for Father's Day?

Father-son matching shorts are a fun Father's Day gift. Coordinated swimsuit sets look good during beach vacations, pool parties, and summer activities. All of our father matching collections make thoughtful gifts, including father-daughter sets and complete family coordinating pieces.

Which swim trunk style works best for different body types?

Euro shorties suit athletic builds and active swimmers who want freedom of movement. Classic swim trunks with 8-inch inseams flatter most body types and fit comfortably for most water activities. Board shorts provide extra coverage, a relaxed fit, and more rash protection for all-day wear in or out of the water.

Are SwimZip’s father-son swim trunks suitable for sensitive skin?

Our swim trunks don’t irritate sensitive skin. Tagless construction eliminates scratchy labels that can cause irritation and rashes. Soft liners feel gentle against skin, while flat-seam stitching prevents the rough edges that often cause chafing during swimming and beach activities. The quick-dry fabric pulls moisture away from your skin instead of trapping it, which reduces the risk of rashes and bacterial growth that can worsen sensitive skin conditions.

Can swim shorts double as regular shorts for other activities?

You can take our swim shorts beyond the water. Quick-dry fabric and a comfortable fit make our swimwear suitable for beach volleyball, playground visits, and casual summer outings. Many families use them as versatile travel pieces since they transition from water to wherever you want to go. UPF 50+ protection continues working during outdoor play, giving you sun safety all day, everywhere.
