We're parents too.

After struggling with diapers, confusing methods, and too many messes, we realized there was a better way.

So we teamed up with pediatricians and designers to create training underwear that actually helps kids learn — instead of just managing accidents.

Thousands of parents later... it's still the product we wish we had from 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 — with fewer messes and more wins.

👕 Feels like real undies (because they are)

Be sure to use a warm or cold wash, and delicate setting where possible!

UpAiry underwear is designed primarily for daytime training — where your toddler is awake, aware, and learning body cues.

Nighttime dryness is a different journey, and most children take longer to master it. That said, many parents use UpAiry for night time and find success while transitioning out of diapers.

For heavy night wetting, we recommend pairing with a waterproof mat or our extra inserts for extra peace of mind.

Made from premium fabrics and a waterproof outer layer, our UpAiry Training Underwear ensure a pleasant experience for your toddlers during potty training.

These underwear feature six layers of eco-friendly materials designed to be gentle on the skin, provide maximum absorbency and protection, and include a leak proof outer layer with fun, cotton designs.

Here's the technology infused in your favorite UpAiry Training Underwear:

The Inner Layer
The inner layer is crafted from high-quality cotton that is undyed and unbleached, making it safe for your child's delicate skin. This cotton fabric is breathable and comfortable, helping to prevent skin rashes and protect against pollen, dust mites, and allergens.

Our potty training underwear stands out with its innovative 2-layer design, ensuring a unique experience for both parent and child. Here's the breakdown:

First Layer [Leakproof]: Unlike diapers or pull-ups, this layer doesn't absorb wetness. Instead, it allows your child to feel the discomfort, aiding in their awareness. Plus, it prevents leaks, so you won't have to deal with puddles or soiled sheets.

Second Layer [Backup]: Acting as a safety net, this layer ensures that any potential leaks are contained, providing extra peace of mind.

With our UpAiry Underwear, you get the best of both worlds: a comfortable, cute design for your child and a stress-free potty training experience for the whole family.

Our sizes are based on weight. If you are unsure or are in-between weights, its best to size down due to the Underwear being stretchy!
