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 moisture — key for learning.
Bedwetting alarms can be intrusive and stressful, waking 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 is 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.
