Whether it's sprinklers in the backyard, a trip to the beach or swimming lessons at the local pool, there's no denying that little ones love playing in the water. However, regular diapers are simply not designed to withstand water play; their absorbent abilities will only leave your baby or toddler with a sopping wet anchor around their waist.

If your kiddo isn't yet potty trained, then you should make sure to have swim diapers on hand. This we know, so we took a look at the best swim diapers on the market right now.

There are two types of swim diapers: reusable and disposable. Disposable diapers are designed for one-time use, so they're not as eco-friendly, but they are convenient especially when it comes to quick and easy clean ups. Reusables, like our top pick the Beau and Belle Nageuret Reusable Swim Diaper (available at Amazon) , are more environmentally friendly and often cheaper in the long run, but require more planning since they can't be used after they've been soiled.

No matter which you prefer to use, a swim diaper should offer a snug fit and be durable enough for all-day play at the pool or beach.

We’ve rounded up top-rated reusable and disposable swim diapers used by our own editors so you can have a mess-free summer swimming with your little one.

Editor's Note:

The recommendations in this guide are based on thorough product and market research by our team of expert product reviewers. The picks are based on examining user reviews, product specifications, and, in some limited cases, our experience with the specific products named.

Huggies Little Swimmers

Huggies are well known in the diaper world, so it comes as no surprise the longstanding brand makes a great swim diaper, too.

Little Swimmers are designed with double leak guards and feature an adjustable fit and resealable sides. The diapers are free of fragrances, parabens, elemental chlorine, and natural rubber latex, making them a good pick for little ones with sensitive skin.

Sizes include small (16-26 pounds), medium (24-34 pounds), and large (32 pounds and up). Huggies also makes an extra-small size that fits babies 7 – 18 pounds; while this size is harder to find, it is one of the only disposable options for newborns.

While testing, we found the Little Swimmers were a great fit for smaller and skinnier kids.

Pros

  • Available in extra-small

  • Fits well

  • Resealable sides

Cons

  • Extra-small can be hard to find

Thirsties Swim Diaper

Thirsties reusable swim diapers have a soft mesh interior to keep young children comfortable while they splash and play in the water. The diaper is designed with leg gussets that prevent messes from leaking out. But since there's no absorbency with this diaper, you’ll want to wait to put it on your little one until you arrive at the pool (and have a regular diaper on hand for when they’re spending time out of the pool).

Thirsties swim diapers are available in a variety of playful designs and come in three sizes: size one (6-18 pounds), size two (18-40 pounds), and size three (35-55 pounds).

During testing we found the Thirsties as easy to put on as a standard diaper, and the adjustability helped them last through multiple summers.

Pros

  • Soft mesh

  • Smaller sizes

  • Adjustable

Cons

  • No absorbency

What You Should Know About Swim Diapers

How Do Swim Diapers Work?

The main purpose of swim diapers is to keep poop contained while kiddos swim and splash around. The best swim diapers do just that.

While regular diapers are made to absorb liquids, swim diapers are made to withstand water and keep solids contained, so they don’t contaminate swimming areas. If you’re wondering if that means that pee can escape, well, yes. Unless your baby is wearing a waterproof outer shell, pee will pass right through.

While no one likes to think about swimming in pee, the reason why fecal matter is the main issue addressed by most swim diapers is that fecal accidents are the main cause of waterborne pathogens in public pools, according to the Centers for Disease Control and Prevention. Particles of poop are what is going to make people sick when they are swimming.

That said, you should never, ever take your baby to a pool (public or otherwise) if they have diarrhea or if they are still making liquid newborn poops. No matter what type of protection you have on them, it’s best to keep any water play to the bathtub or a kiddie pool at home for young babies and children of any age that are experiencing liquid stools.

Because most swim diapers are not designed to hold liquids, it's a good idea to pack your preferred regular diapers as well for the times that your kid will be out of the pool or for the ride to and from your water play. The CDC also recommends that swim diapers and pants should be changed away from the pool and to plan to check or change the diapers every 60 minutes or so.
