Our Top Picks

Best Overall: I Play Snap Reusable Swimsuit Diaper

Reusable swim diapers are a great idea for anyone who swims a lot. Even for families that prefer disposable diapers for every day, reusable swim diapers are actually easy to use since you just will need to clean up number two if it occurs during swim time. With that being said you should always be sure to have another one or two reusable (or disposable) pair for when they do go and you can't wash them on-the-go.

The basic but effective swim diaper by I Play gets our vote for the best reusable swim diaper. Snaps on the sides prevent you from having to pull a dirty diaper down over baby’s legs and feet. And three layers of protection ensure a comfortable, confident swim. The inner layer is a wicking layer to prevent diaper rash, while an absorbent middle layer works alongside the waterproof outer layer to prevent embarrassing leaks. I Play diapers provide a good fit to a variety of body sizes and come in a huge variety of adorable colors and designs, including basic white.

Best Budget: Huggies Little Swimmers Disposable Swimpants

Looking for a swim diaper that won’t blow your summer budget or need to be washed on vacation? Try Little Swimmers by Huggies. You can buy a whole package of these disposable swim diapers for about the price of one or two reusable swim diapers. And aside from the great price, the disposable feature means no sloshing yucky diapers in the toilet while missing out on fun in the sun—just throw the soiled diaper away and start fresh!

Like almost all swim diapers, Huggies Little Swimmers don’t hold in pee very well but keep in mind that the major objective of swim diapers is to contain number twos effectively. They also have easy open sides for when number two does occur so cleanup is a lot easier than pulling them down.

Best Reusable: Bummis Swimmi Swim Diaper

In our opinion, Swimmis by Bummis are the best reusable swim diapers. And we’re not alone! The Bummis brand has been loved and trusted by cloth-diapering families for years. Swimmis are comfortable, reliable and effective when it comes to containing accidents pool-side. In fact, many parents say they’ve turned to Bummis when several other brands failed to impress them. One of the biggest compliments Bummis regularly receives is the excellent fit around the thighs without causing the baby any chafing pain or red lines from a too-tight fit. Plus, their one-size version fits baby's from 8 to 36 pounds (the snap closure helps them stay fit as they grow) so they will be with you for the long haul and make a great pair of swim diapers for toddlers.

Bummis come in tons of adorable designs to choose from, and the outer fabric has built-in UV protection too. So if you’re looking for the best reusable swim diaper, we definitely recommend Swimmis by Bummi.

Best for Babies: Splash About New and Improved Happy Nappy

Babies under 6 months of age generally have much more runny diapers since they are typically fed a liquid diet of breastmilk or formula and don't start solids until around 4 to 6 months. Containing that liquid can be extra challenging when it comes to swimming so you'll want to look for a swim diaper that fits super snug around the thighs and back to prevent leakage.

Thankfully this pair of swim diapers are made of neoprene (think a wet suit) so it fits great and will conform to your rapidly growing baby's size. A snug fitting backside makes sure nothing escapes while they are splashing around and they are also UPF 50+ so your baby will be protected when they are having fun in the sun. These diapers come in various sizes, 0-3, 3-6, 6-12, 12-24, and 24-36 months so you can find the perfect fit for your baby.

Best Disposable: Pampers Splashers Diaper Sesame Street

While reusable diapers can save you some money and are better for the environment, disposable diapers make going to the beach easy. Much like regular disposable diapers, these diapers are single use. Sadly, disposable swim diapers can be quite costly.

This top pick from beloved brand Pampers does the job and has removable side tabs which make disposing of soiled diapers pain and mess free. These diapers are much like the Huggies diaper, except they feature Sesame Street.

Of course, keeping everything contained is the main objective when buying a swim diaper, but you also want your little one to look cute! The BabyGoal swim diaper not only keeps everything inside but they come in an array of sweet patterns that make a statement all by themselves.

Parents rave about these swim underwear with many reviewers saying they didn't even know their child had gone to the bathroom since they held everything in so well. Some note figuring out how to button them the first time can be challenging but after they are done once you won't need to fuss around again.
