The best swimsuits for kids

The best swimsuits for kids
  • A kids' swimsuit should protect your child against the sun while offering an easy range of motion for swimming, treading, wading, and playing out of the water.
  • The City Threads Rash Guard Swim Shirt is our top pick for the best kids' swimwear because its SPF/UPF 50+ fabric offers excellent coverage to protect skin from neck to wrist to waist.

Most kids love playing at the beach, swimming in the pool, or splashing in water tables. But when it comes to swimming and water play, a child's primary concern is fun, not sun protection. Fortunately, parents have many swimwear options to choose from, which offer sun protection, versatile and fun designs, and high-quality fabrics.

As you choose the best swimsuit for your child, it's important to consider their age, their abilities, and the likely activities during which they'll use the swimsuit.

A baby needs total sun coverage, for example, while a 4-year-old can be sufficiently protected using sunscreen and a hat. A toddler may love their board shorts, but if you top off their aquatic ensemble with a rash guard shirt, you can prevent sunburns and scratches, too. A versatile one-piece suit offers performance during actual swimming or strenuous play. We took all of this into consideration to round up swimsuits for babies, toddlers, and older kids.

Here are the best kids' swimsuits you can buy:

The best kids' swimsuit overall

The best kids
City Threads
The City Threads Rash Guard Swim Shirt is soft and comfortable and designed to keep your little one protected from sunburns.

The City Threads Rash Guard Swim Shirt are comfortable whether wet or dry, and they come in both long- and short-sleeve cuts and in more than 10 different colors, so you'll be able to pick one your child will like.

They dry quickly so your child won't mind wearing one after getting out of the water, and they are lightweight and breathable enough for use even on hot and humid summer days. The alternative is to slather sunblock all over your kid's arms and torso every couple of hours, and that's a proposition that both kids and parents will surely agree is the less desirable option.

Pros: Excellent SPF/UPF protection, unisex design, soft and comfortable fabric

Cons: Sizes run large

The best swimsuit for babies and toddlers

Amazon
The Snapper Rock Baby Long Sleeve Sunsuit is absolutely charming, soft, breathable, and blocks 98% of the sun's harmful rays.

I might be a bit biased here, because the Snapper Rock Baby Sunsuit is the first bathing suit my newborn daughter ever wore, but this baby swimsuit is one of the most charming pieces of swimwear I've ever seen. And the fact that a half zipper down the torso makes the sunsuit easy to put on a wiggly newborn is another plus.

But what really counts here is performance. This swimsuit offers coverage from a baby's neck to their hands and down to their feet, and that coverage comes complete with UV50+ protection against sun damage. The 80% nylon, 20% elastane fabric blocks 98% of the sun's harmful UV rays and also ensures that the sunsuit is comfortable and flexible, allowing baby to twist and squirm and even to crawl around if they're an early mover. The fabric also dries quickly, so your infant won't get cold and clammy after water play is over.

The Snapper Rock Baby Long Sleeve Sunsuit is a bit on the pricey side for a garment that definitely has only a single season of use in store, but it's worth it for the quality you'll find.

Pros: Full body sun coverage, soft and flexible material

Cons: Pricey

The best one-piece swimsuit

Speedo
The Speedo Infinity Splice One Piece Swimsuit is the perfect choice for diving, swimming, surfing, and running around on the sand.

A well-made one-piece bathing suit is ideal for both energetic activities at the beach or pool. The Speedo Infinity Splice One Piece Swimsuit is made of an extra durable and flexible nylon and Lycra blend, so it stays in place and won't stretch out over time, either. Silicone grippers at the leg openings keep the suit in place and the thick shoulder straps and racerback design help the suit stay close to the skin during swimming, running, paddle boarding, and so on.

The Infinity Splice suit comes in several different color patterns and in multiple different sizes, so younger and older children can find a suit they like that will fit just right.

Pros: Versatile fit, comes in multiple sizes, durable materials

Cons: Sizes run small

The best board shorts

The best board shorts
Snapper Rock
The Snapper Rock Boys Boardie Board Shorts are made with the same exacting quality as a great adult board short, they just happen to be smaller.

My son has two pairs of Snapper Rock Boardie Board Shorts. He has worn them while throwing water balloons around the yard, while we're out on the Long Island Sound in a kayak, and while playing at the beach, too, and these durable, comfortable trunks have always performed perfectly.

The Snapper Rock Boardie Shorts are stylish enough to wear them around all day during the summer, yet they are designed primarily for function. The shorts are lightweight and quick to dry, and they have an elastic and drawstring waistband. A mesh liner ensures comfort and breathability.

Like other Snapper Rock swimwear, these cost a bit more than you might want to spend on something a child will eventually outgrow, but at least you can count on them loving their board shorts as long as they fit.

Pros: Secure and comfortable waistband, built-in mesh liner, lightweight yet durable fabric

Cons: Expensive option
