The Best Boys’ Swimsuits

Buying Guide for Boys’ Swimsuits

A boy plays with sand in a rash guard and swim trunks at the beach.

Why should you buy a boys’ swimsuit?

Even though your enthusiastic boy may be perfectly content wearing his favorite gym shorts when jumping in the pool, he’ll have a much better experience if he can splash around wearing a quality swimsuit that fits his body and style well. Swimsuits are designed to withstand the friction and force of water, dry quickly, and hold up to pool chemicals or salty ocean water. So, next time your little guy tries to bring basketball shorts to the pool, toss him his new swimsuit instead.

What should you consider when shopping for a boys’ swimsuit?

  • Material: Swimsuit material differs from the material used for regular play or sports shorts. Swimsuits are usually made from nylon, elastane, polyamide, or any blend of these, and the material will be fast-drying and durable to endure elements like sun, sand, salt, and chemicals like chlorine. These days, swimsuits are also designed to provide protection from the sun’s rays.
  • Coverage: A boy’s swimsuit can be a simple pair of trunks or a one- or two-piece that provides more coverage for his arms or torso. Some options that provide extra coverage come in two-piece designs with a short- or a long-sleeve rash guard paired with trunks. Other options are one-pieces that use a full-length zipper for easy dressing.

What is a rash guard?

If you’re not sure what a rash guard is when shopping for swimming suits, you’re not alone. A rash guard is simply a tight-fitting swimsuit top that covers more of the body from environmental factors (i.e., sun, sand, salt, chlorine). People who do water sports may prefer the protection and coverage a rash guard provides, and they also make it easier to protect your kids from sunburns. Most rash guards will be in the form of a t-shirt or long-sleeved shirt that accompanies trunks or another bottom piece.

Our Picks for the Best Boys’ Swimsuits

Best for Babies and Toddlers

Simple Joys by Carter's Toddlers and Baby Boys' Swimsuit Trunk and Rash Guard

Keep your little one comfortable and protected while he enjoys the water.

Pros: Your little kiddo has much more sensitive skin than you, so he needs more protection from the sand and the sun. This two-piece can help. The trunks are easy to pull on and off and are lined with mesh to help them dry faster. This set comes with a short-sleeve rash guard with a cool color block design that protects against UV rays. This set is available in seven different designs.

Cons: When it comes to children’s clothing, sizing can often be a challenge as kids can grow quickly and have varying body shapes. Many parents have suggested ordering a size up if your child is in between sizes. It’s best to hand wash this set in cold water and hang or lay it flat to dry.

Bottom Line: Feel some peace of mind knowing your little one’s skin is protected while he explores. A functional drawstring keeps the trunks in place no matter what fun your little one gets into.
