We’re parents too. After wrestling with diapers, conflicting methods and far too many messes, it was clear there had to be a better way.

So we sat down with pediatricians and designers and built training underwear that actually helps a child learn, instead of just managing accidents.

Thousands of parents later, it is still the product we wish we had on day one.

We’re not diapers. We’re not pull-ups. We’re not plastic.

UpAiry is real underwear that helps your toddler potty train faster — fewer messes, more wins.

• 🚽 Feels like real undies (because they are)
• 💧 Absorbs small accidents without bulk
• 💪 Builds your child’s confidence
• 🧠 Supports popular methods like Oh Crap
• 🧺 Washable. Reusable. Eco-friendly.

Rinse if you need to, throw them in the machine, dry. They are made to survive hundreds of washes — because you are going to need them to.

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

Use a warm or cold wash, on a delicate setting where possible.

UpAiry underwear was designed mainly for daytime training, when your toddler is awake, aware and picking up on body cues.

Staying dry at night is a separate journey and most children take longer to get there. Even so, plenty of parents use UpAiry overnight and do well with it while moving away from diapers. For heavy night wetting we suggest pairing it with a waterproof mat or our extra inserts.

Premium fabrics and a waterproof outer layer make UpAiry Training Underwear a pleasant experience for your toddler during potty training. Six layers of eco-friendly materials sit gently on the skin, deliver maximum absorbency and protection, and finish in a leak proof outer layer with fun cotton designs.

The Inner Layer — high-quality cotton, undyed and unbleached, safe for delicate skin. It breathes, keeps things comfortable and helps guard against rashes, pollen, dust mites and other allergens.

The Middle Layers — the absorbency core: a sheet of high-quality absorbent cotton plus three layers of thick gauze, which is what gets UpAiry to the level of absorption we ask of it.

The Outer Layer — TPU waterproof fabric that keeps fluid off skin and clothes. Thermoplastic Polyurethane carries no harmful solvents or chemicals, so it stays toxin-free and environmentally friendly, and it is topped with a hypoallergenic cotton cover in prints your toddler will love.

The 2-layer design is what sets them apart, for you and for your child:

First Layer [Leakproof]: unlike a diaper or a pull-up, this layer does not soak the wetness away. Your child feels the discomfort — which is exactly what builds awareness — while leaks stay contained, so no puddles and no soiled sheets.

Second Layer [Backup]: the safety net that holds any leak that gets through.

You end up with both halves at once: a comfortable, cute design for your child and a stress-free potty training experience for the whole family.

Sizing goes by weight. If you are unsure, or your child sits between two weights, size down — the underwear is stretchy. The full size guide is below.

Yes. Every UpAiry pair is unisex and works just as well for boys and girls.

The absorbent area sits where it is needed most, and the design stays neutral enough for any toddler to feel like a “big kid” in them.
