Potty Training Underwear

We're parents ourselves.

Between the diapers, the conflicting advice and one mess after another, we knew there had to be a better path.

So we brought pediatricians and designers together to build training underwear that actually teaches kids — instead of only cleaning up after them.

Thousands of families later… it's still the product we wish had existed on day one.

They're not diapers.

They're not pull-ups.

They're not plastic.

UpAiry is genuine underwear that gets your toddler potty trained sooner — with fewer messes and a lot more wins.

• 🚽 Feels like real undies (because that's what they are)
• 💧 Soaks up small accidents without the bulk
• 💪 Grows your child's confidence
• 🧠 Works alongside popular methods such as Oh Crap
• 🧺 Washable. Reusable. Eco-friendly.

Give them a quick rinse if needed, throw them in the machine and dry them. They're built to survive hundreds of cycles — because, let's be honest, you're going to need that.

• 🧼 Machine washable
• ♻️ Reusable + eco-friendly
• 👶 Still wonderfully soft after 100's of washes

Stick to a warm or cold cycle, on the delicate setting whenever that's possible!

UpAiry underwear was built mainly for daytime training — the hours when your toddler is awake, alert and learning to read body cues.

Staying dry overnight is a separate milestone, and most children need longer to reach it. Even so, plenty of parents use UpAiry at night and do well with it while moving away from diapers.

For heavy overnight wetting, we suggest pairing them with a waterproof mat or our extra inserts for added peace of mind.

Built with premium fabrics and a waterproof outer shell, our UpAiry Training Underwear keeps potty training pleasant for your toddler.

Each pair is made of six eco-friendly layers, chosen to stay gentle on the skin, deliver maximum absorbency and protection, and finish with a leak proof outer layer wrapped in playful cotton prints.

Here's the technology packed into your favorite UpAiry Training Underwear:

The Inner Layer

The layer closest to the skin uses high-quality cotton that is left undyed and unbleached, so it stays safe for your child's delicate skin. It breathes, it feels comfortable, and it helps keep rashes, pollen, dust mites and other allergens away.

The Middle Layers

These "absorbency" layers combine a sheet of high-quality absorbent cotton with three layers of thick gauze. They're what make the level of absorption UpAiry demands possible.

The Outer Layer

The outermost layer uses TPU Waterproof fabric, shielding your child's skin and clothes from any fluid. Thermoplastic Polyurethane (TPU) carries no harmful solvents or chemicals, so it stays toxin-free and kind to the environment while keeping your child safe. On top of it sits a cotton cover with the fashionable prints and designs your toddler will love — and it's hypoallergenic!

Our potty training underwear works differently thanks to an innovative 2-layer construction that changes the experience for parent and child alike. Here's how it breaks down:

First Layer: unlike a diaper or a pull-up, this layer doesn't lock the wetness away. It lets your child notice the discomfort, which is exactly what builds awareness. At the same time it holds things in, so you're not mopping puddles or stripping sheets.

Second Layer: a safety net that cuts down whatever might still escape, giving you extra peace of mind.

With UpAiry Underwear you get both sides: a comfortable, cute design for your child and a stress-free potty training stretch for the whole family.

Sizing runs by weight. When you're unsure, or your child sits between two weights, going one size down is the safer pick — the underwear is stretchy!

The complete size guide is right below:

Absolutely! Every UpAiry pair is unisex and performs just as well for boys as it does for girls.

The absorbent zone sits exactly where it's needed most, and the look stays neutral enough for any toddler to feel like a "big kid" in style.

Every pair carries a triple-layer absorbent core that keeps leaks and messes down. They are not leakproof the way a diaper is, though. A bigger accident, or a full night of wear, can still let some wetness through. Think of them as the right choice for daytime accidents while potty training is under way.
