What is a Reusable Cloth Swim Diaper?

Swim diapers are diapers that can be used in water, including at pools, beaches, water parks, and other splashy places. They’re made in both reusable and disposal form, but since we’re eco-friendly here, we’re only talking about cloth-based reusable swim diapers.

How Do Cloth Swim Diapers Work?

Unlike regular diapers that are designed to absorb liquids, most swim diapers allow liquids to pass through them. In other words, they don’t catch the pee, only poo.

It might sound a bit messy, but it’s a necessary evil: Can you imagine your baby wearing a water-absorbent diaper in a swimming pool? They’d puff up like a penguin the second that they hit the shallow end!

Another thing to note is that reusable swim diapers aren’t the same thing as regular reusable diapers. The latter is usually just cloth while the former is made with multiple layers of waterproofing materials as well as snaps, elastic bands, and other ways of ensuring a tightly sealed fit.

How To Choose Reusable Swim Diapers?

With so many swim diapers on the market, you might feel like you’re drowning in sharks and sea shells patterns. Here are just a few ways to cut through the riff-raff and find the products worth buying.


Just like regular diapers, swim diapers come in a variety of styles. They can look different, have different fits, and come with different enclosures such as snaps, buttons, and Velcro strips. There are also different designs for different stages of potty training. A full-coverage baby swim diaper won’t look the same as a pullup-style toddler swim diaper.


Reusable swim diapers can be made from polyester, rayon, neoprene, spandex, polyurethane, and more. They’re often designed with multiple layers or fabric blends that combine materials. If they have liners, the liners are usually made with something different than the softer inner layers.


Some swim diapers come with elastic bands to prevent leaks and hold them in place even if the diaper gets heavy. They’re also common on adjustable, multi-age diapers that are designed to accommodate a growing infant over time.


Are you on a budget? Or do you just hate shopping for diapers? Many swim diapers come with adjustable fits that can be worn over months or even years. Some of the longer-lasting brands can survive your child’s entire infancy!

Sun Protection

Certain types of fabric can offer sun protection. Just like sunscreen, they’re measured in ratings like UPF 30, 40, 50, and so on. Other types of sun protection from swimwear can come in the form of shaded bucket hats and long sleeve onesie-style suits. These can be combined with swim diapers for the highest amount of UVA/UVB protection.

Do you put a diaper under a reusable swim diaper?

Nope, don’t do this! A swim diaper is specifically designed to be non-absorbent; that’s why it doesn’t puff up from the water of a swimming pool. If you put on a regular, absorbent diaper underneath a swim diaper, you’ll just be adding a layer that’ll get heavy and soggy over time.

How to wash cloth swim diapers?

Swim diapers can be washed just like any other cloth diapers. Depending on the fabric, this might mean tossing them in the washing machine, soaking them in the sink, or scrubbing them by hand. It all depends on the brand that you buy.

Here’s more information about how to wash cloth diapers.


Reusable swim diapers can take a lot of stress out of family outings to the beach. They’re cute, easy to use, environmentally friendly, and just as clean as any other kind of swim diaper. Embrace summertime fun with cloth swim diapers for all of your wee ones!
