Note from Karen: The important thing to know about all washable, reusable swim diapers is that they are designed to contain poop. They are not thick diapers and are not designed to do much at all about pee. They are just for soil containment. This has some light padding, but don't expect a full pee-flood to be contained fully in the car seat in a swim diaper. Use a diaper when a diaper is needed. A swim diaper is not the same thing as a diaper and it not the same thing as a diaper cover. The fit is different. Proper swim diapers fit snuggly. They will not allow a big air bubble to form inside them and possibly tip baby's face down as the air rides up, which is scary. The snugger shape of the swim diaper means they don't fill up with a big puddle of heavy water when you lift baby out of the water, either. A swim diaper that fits properly shouldn't be very saggy but should fit reasonably snug to the body. We do not suggest using diaper covers as swim diapers. Choose a real swim diaper for swimming.

Perfect fit under swimsuit

I was originally planning on buying a rashguard to pair with this swim diaper but it’s so trim that it fits under a swimsuit perfectly, it doesn’t even show on the sides!

Thirsties Swim Diaper - Fantastic!

I love this product! Can't wait to use it!


Great swim diaper

If you love thirsties diaper covers, you will love this swim diaper. The fit is great on chunky baby legs- comes down nicely over the leg to keep everything contained. Looks nice enough to wear alone and washes well (I wash it with our swimsuits unless it gets pooped in). Dries quick too.
