What Size Should I Get?

Just go by weight! Our sizing is based on real toddler bodies — not guesswork. 

 

Our sizes typically run:
- Small: 1-2 years (7-20 lbs | 3-9 kg)
- Medium: 2-3 years (22-35 lbs | 10-16kg)
- Large: 3-4 years (35-55 lbs | 17-25kg)

 

If you're in between sizes, we recommend sizing up for more comfort.

 

💡 Bonus: Every order is covered by our 75-day fit guarantee. If it’s not right, we’ll exchange it for free — easy.

Is this better than pull-ups?

Yes — and here’s why. 

 

Pull-ups feel like diapers… so kids treat them like diapers. That’s the problem. They don’t feel when they’re wet — which delays learning.


UpAiry is different. It looks and feels like real underwear, but has just enough built-in absorbency to catch small accidents without making your toddler lazy. That sensory feedback helps them connect “I need to pee” with “I should go potty.”


It’s the difference between managing messes and actually making progress.

What if my toddler refuses the potty?

That’s normal and more common than you think — and it doesn’t mean you’re failing.


A lot of toddlers resist potty training because it feels like pressure. UpAiry takes that pressure off by giving them real underwear they feel proud of. No gimmicks. No shame. Just the feeling of being in control.


We’ve seen the most “stubborn” kids suddenly want to try — simply because they get to wear undies like a big kid.


Sometimes, that’s all it takes.

How does it actually work?

Feel & Learn™ is our signature absorbent gusset that helps your toddler feel when they’re wet — without flooding the floor. 

 

It’s the perfect balance: enough protection for little leaks, but just enough feedback to help them learn what’s happening and get to the potty next time.

 

✅ Helps your child connect body signals
✅ No bulky diaper feeling
✅ Speeds up potty learning naturally

Every material that touches the skin is 100% cotton making our training pants hypoallergenic.

Can I use them overnight?

Yes! Our training pants are designed to keep your child dry and comfortable all night. They’re leak proof but still let your child feel when they’re wet, helping with potty training even during sleep.

 

We recommend getting some extra absorbent inserts or Waterproof Mat for nighttime training for extra leak protection.

Can it handle poop accidents?

Yep — they’re designed to handle that too. Solid poop? Just shake it into the toilet and toss the undies in the wash. 

 

For messier moments, a quick rinse first helps. Either way, you’re covered.

 

💩 Handles the full potty journey
🚽 Easy to clean
🧽 Toddler-proof

 

For best results, make sure you've chosen the right size - our underwear should fit snugly around your child's legs without being too tight.

Frequently Asked Questions

Who created UpAiry and why?

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.

What Exactly Is UpAiry?

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)

 

💧 Absorbs small accidents without bulk

 

💪 Builds your child’s confidence

 

🧠 Supports popular methods like Oh Crap

 

🧺 Washable. Reusable. Eco-friendly.

How do I Wash Them?

Just rinse (if needed), toss in the wash, and dry. They’re built to survive hundreds of washes — because, let’s be real, you’ll need them to.

 

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

 

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

Is it suitable for night time potty training?

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.

Our technology

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 organic 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! 

How are these different than disposables?

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.

I'm not sure what size to order?

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:

Is UpAiry Underwear suitable for both boys and girls?

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.
