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.

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 other allergens.
The Middle Layers
These “absorbency” layers consist of a sheet of high-quality absorbent cotton and three layers of thick gauze. These layers are crucial for achieving the high level of absorption that meets UpAiry’s standards.
The Outer Layer
The outermost layer is made from TPU Waterproof fabric, which protects your child’s skin and clothes from any fluid. Thermoplastic Polyurethane (TPU) is free from harmful solvents and chemicals, making it a toxin-free and environmentally friendly option that ensures your child’s safety. This layer also features a cotton cover that has fashionable prints and designs that your toddler will love, making it hypoallergenic!
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: 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: Acting as a safety net, this layer helps reduce that any potential leaks, 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!
You can find the full size guide below:
Yes! All UpAiry underwear is unisex and works great for both boys and girls.
The absorbent area is built where it’s needed most — and the design is neutral enough for any toddler to feel like a “big kid” in style.
We design our underwear with a triple-layer absorbent core that helps reduce leaks and messes. However, they’re not leakproof in the way a diaper is. If your child has a larger accident or wears them overnight, there may still be some leakage. These are best for daytime accidents during active potty training.

"We tried everything—nothing worked. These pants actually helped her understand what going potty meant. It just made sense to her in a way disposables didn’t."

"He hated being wet but didn’t care when it was a diaper. Once we switched to these, he started telling us when he had to go. It finally clicked and how hes fully trained!!"

The first time my daughter got up and ran to the bathroom BY HERSELF I couldn't believe it!! 😂 She used to just pee and carry on with whatever she was doing. Now she doesn't want to mess up her big girl undies. Not having to constantly remind her to go is honestly the BEST feeling!!
391My son was almost 3 and REFUSED to use the potty. We'd tried the books, the sticker charts, even bribing him with treats lol. Nothing worked consistently. Getting him to actually notice when he had an accident was a big step for us. We still had to remind him to go, but things finally started moving in the right direction.
132We just started potty training, and my daughter absolutely loves wearing her underpants. She gets so excited to put them on, and honestly, so do I! It has made starting this new stage so much more fun and exciting for both of us. We’re so happy with them and definitely recommend them!
