The best reusable swim diapers are easily adjustable and have a snug fit around the legs/waist to ensure that the poop can’t get out.

PS! Swim diapers don’t hold pee, or they would absorb all the pool water.

How Do Reusable Swim Diapers Work?

Cloth diapers for swimming pool use are different from regular cloth diapers as they do not absorb liquid.

Their purpose is to hold in solid waste but let liquids pass through. To do this, they usually have a mesh lining and waterproof polyester outer.

They are pull-ups or fasten with snaps and help prevent fecal matter from getting into the pool water and spreading bacteria.

They have a tighter fit than regular velcro cloth diapers and have elastic at the legs and waist. Along with adjustable snaps, this keeps any solid waste inside the diaper and prevents too much water from getting inside.

Reusable Swim Diapers vs. Disposable Swim Diapers?

You can reuse Permanent swim diaper options, unlike their disposable counterparts.

The best reusable swim diapers have a snug fit and adjustable snaps, whereas you can’t customize disposable ones.

Reusable swim diapers are better at containing poo as they are designed to keep solids in but let liquids out.

Disposable diapers are designed to absorb some wee, which means they absorb water as well. The water causes them to swell up and sag, which can impact their effectiveness.

Disposables are best for infrequent swimmers, but reusable swim diapers are cheaper and better for active swimmers.

How To Choose Reusable Swim Diapers?

The most important thing to look for when choosing a swim diaper is how adjustable it is and whether it has a PUL outer and mesh inner.


Reusable swim pants for babies either have snaps or are pull-ups. Most parents prefer swim diapers with snaps. Snaps on both sides or multiple snaps are the best.

Snaps allow you to adjust the size of the diaper to fit your child snuggly. A better fit not only makes them more comfortable but also stops any poop from leaking out.


Reusable infant swim diaper options need to be adjustable so they can grow with your child. This makes them cost-effective.

Customizing the fit makes it easier to contain blowouts and is more comfortable for your child. Reusable swim diapers should have elastic at the legs and waist and snaps.


There should be elastic at the legs and waist to ensure a snug fit that prevents poo from leaking out. It should be covered in fabric but not sewn through, or it will scratch.

Sizing happens by weight, and there should be no more than two fingers between the body and the elastic.


Reusable swim diapers should be lightweight and snug. A waterproof outer and a fine hole mesh lining will ensure water isn’t absorbed.

The most commonly used is polyester, and this is durable and washable. Choosing a non-absorbent fabric is important to prevent sagging and poo leaking out.

Snaps work better than Velcro.

Sun Protection

Looking for a reusable swim diaper with an ultraviolet protection factor is important. Many of them have a UPF of 50+, meaning 98% of harmful UV rays have no effect.

Not only is sun protection important in your swim diaper, but you should use it in conjunction with a broad-spectrum sunscreen.


Are reusable swim diapers good?

Yes, they are effective for preventing toilet accidents in the pool and healthier for sensitive skin. However, they are also cost-effective and earth-friendly.

Do you put a diaper under a reusable swim diaper?

No. Reusable swim diapers are designed to contain solid waste and let liquid waste pass through. Some public pools do require double diapering, however.

Do reusable swim diapers hold pee?

No. The polyester mesh lining is designed to allow pee to pass through. The diaper is only effective if it does not absorb liquid.

Do reusable swim diapers hold poop?

Yes. The polyester mesh lining effectively stops solid poop from leaking out. That is why a snug fit and elastic at the legs and waist are important.

Do reusable swim diapers work with breastfed babies?

No. The mesh lining is designed to prevent solid waste from leaking. Breastfed babies have water-soluble, soft poop, which could leak out like pee.

Can cloth diapers be used as swim diapers?

No. Cloth diapers are designed to absorb liquid so they would become waterlogged. This would cause sagging and leaking. It would also be uncomfortable and heavy for your child.

How do reusable swim diapers work?

They are worn like regular diapers but are designed to contain poop and not absorb liquids. This prevents fecal matter from contaminating pool water.

How to use reusable swim diapers?

Put the diaper on and secure it with snaps. Use them to create a snug fit that is comfortable but tight enough to prevent poop leakage.

How many reusable swim diapers do I need?

You should have two reusable swim diapers for a visit to the pool. That allows your child to wear one, and you have a spare in case of a blowout.

How to wash cloth swim diapers?

Rinse the diapers to remove poop, chlorine, and pee. Then wash in a machine on cool. Either hang to dry or tumble dry on cool depending on instructions.

How long can a baby wear a cloth swim diaper?

You only need to change the swim diaper if your child has pooped but leaving a wet diaper on can cause rash and irritation.

Why do some places require both disposable and cloth swim diapers?

Some public pools require disposable and cloth swim diapers for health and safety reasons. This double layer provides extra protection from poop.
