Diapers are made to absorb—that’s how they do their job! But that’s also why regular nappies won’t do when it comes time to hit the beach or pool. Put one in water, watch it expand and suddenly you’re faced with a major baby bubble butt! (Or just a soggy sack that won’t hold anything in.) Swim diapers, on the other hand, won’t inflate when they touch H20. They’re specifically designed to be fully submerged and still fit your child properly and comfily. The best baby swim diapers keep solid waste secure so you aren’t faced with an embarrassing mess. The only caveat? Most won’t contain pee (or anything else liquidy—beware). So once baby’s back on land, be sure to switch into a normal diaper again. Note that newborn swim diapers aren’t really a thing, either, since newborn poop is typically more watery.

Ready to shop? There are reusable swim diapers and disposable swim diapers on the market, so no matter which style you prefer, you’ve got protection. Here, we’re sharing our favorites in both categories.

Best Reusable Swim Diapers

Cut down on waste—well, at least one kind—with reusable swim diapers you can wash for baby to wear again and again. The following cloth swim diapers are cute and functional.

These beach and pool swim diapers get rave reviews and come in dozens of adorable prints. Better yet, they’ve got a patented three-layer design: an absorbent inner layer to protect against leaks outside the pool, a wicking liner to help avoid diaper rashes and a waterproof outer layer to keep mid-swim messes fully contained.
