Wee, poo, or both? No biggie. Nundies are here for you and your little one — day and night.
Holding up to 1000mL (yep, that’s a lot), they’re soft, comfy, and sensory-friendly, with leak guards to catch rogue drips. They feel just like real undies — and once they’re on, they vanish under clothes like magic.
No bulk, no crinkly noises. Just skin-friendly comfort that’s hypoallergenic, dermatologically tested, and latex-free.
We don’t just say “leak protection”, we mean it.
Nundies are ISO-tested to hold 800mL (Medium 4-7 years) and 1000mL (Large 8-15 years), with a core that turns liquid into gel to keeps things locked away.

Gently fold the pants in half lengthways, then cup your hands over the absorbent pad. Rub your hands back and forth — this helps soften them up and get them ready to fit snugly.
This quick step helps the pants mould to the body and activates the leak guards around the legs — so your little legend stays comfy and protected.
When it’s time to take them off, you can either pull them down or tear the sides — whatever works best for your kiddo.
Nundies are total pros at stopping leaks in their tracks. It's a superpower really!
