When it’s time to make a splash, you’ll want a swim diaper that’s as dependable as it is adorable. Our reusable Swim Diapers are the smarter, more economical choice for frequent splashers, offering comfort, convenience, and fashion compared to disposables.

Swim freely

Our Swim Diapers are designed with a slim, trim cut and a soft mesh interior; they allow your little one to swim freely and comfortably without any extra bulk. No more saggy bottoms either — thanks to the extra-wide elastic at the back, the fit is gentle yet secure, perfect for active water-loving babies.

Quick changes, quick drying

Side snap closures make for quick and easy changes, while the fast-drying, waterproof outer shell and lightweight mesh lining ensure nothing weighs your swimmer down. Available in four sizes for a perfectly snug fit, our Swim Diapers meet — and exceed — the requirements of most public pools, giving you one less thing to worry about during your family's water adventures.

Don't size up

Don't be tempted to size up on these. When you receive your new Swim Diapers, they might look smaller than expected -- but don’t worry -- that's by design! The diaper will expand really nicely when worn and they are roomier than they appear. Unlike our cloth Diaper Covers -- which are cut larger to accommodate absorbent layers -- our Swim Diapers are streamlined to eliminate unnecessary bulk and weight. The precise cut and sizing allows your little one to move freely (and joyfully!) in the water.

Keep two in rotation

We recommend having at least 2 Swim Diapers in rotation. Our Wet Dry Bag is the perfect way to pack a full day's worth of supplies for a day of splashing.

Prep-wash: Wash and dry all of your new Thirsties products with detergent and warm water before use.

So simple to take on and off of baby (especially important that it’s easy to take off because wriggling a baby out of some of those reusable swim diapers out there is too much trouble). The snaps on the sides are key. Great design and function, and baby seems to feel comfortable in them.
