20,000+ training pants sold last month
They're the result of genuine hard work, created hand-in-hand with hundreds of families 👇
✅ Dozens of iterations
We tested, adjusted, then tested again… every stitch, every centimeter, every layer. Nothing was left to chance.
💧 Absorption perfected millimeter by millimeter
Over 11 brands compared. Where they have a simple cotton layer that leaks at the first pee, we developed 5 intelligent layers, including organic bamboo—the most absorbent material. Result: 4x more effective, holding up to 200 ml.
🌿 Carefully selected materials
Organic bamboo, natural cotton, zero toxics. Because several parents told us their children had developed redness and spots with other cheap training pants… we decided to go in the opposite direction.
🎨 Designs that tell a story
We commissioned an American illustrator: each design is exclusive, with a little hidden character as our signature.
👨👩👧 Hundreds of families involved
We listened to your feedback, your concerns, your tips. This Version 2 is yours too: it was born thanks to you.
💸 A price that reflects all this work
Saving a few dollars on training pants that leak actually costs you more: repeated disposable diapers, wet clothes, delayed potty training. Our pants work. They last. They support you all the way to being dry, without compromise.
⭐ The trust that drives us
Today, over 10,000 families have chosen our training pants, with a rating of 4.9/5. And when we read your messages, we know we made the right choice by prioritizing quality, not the easy route ❤️

Night training underwear is a reusable garment specially designed for nighttime. It provides reinforced absorbent protection (up to 12 hours) to prevent leaks during sleep, while still helping your child become more independent and aware of their needs.
Most children can start using night training underwear around the same age they begin daytime potty training. They are designed to provide extra absorption for nighttime accidents, while helping your child feel secure and independent during sleep.
Unlike diapers, they’re reusable and look like real underwear, with strong absorption that still lets the child feel dampness — key for learning.
Bedwetting alarms can be intrusive and stressful, waking up the whole family. Night training underwear offer a gentle, effective alternative for peaceful nights. 
With proper care, our night training underwear can last for several months — even years — depending on usage. They remain effective for over 200 washes without losing absorption.
Yes! Our night training underwear are made with bamboo fibers, cotton and microfibers, all REACH-certified. They’re free from harmful chemicals, gentle on delicate skin, and better for the planet.
Orders are shipped within 24–48 business hours. Delivery times depend on your location and are estimated at 5 to 7 days.
