Locks In Leaks

Leaks? They’re a thing. But Nundies have your kid covered — day or night, number one or number two.

They hold up to 800mL and come with built-in superpowers: soft on skin, comfy, and sensory-safe — with anti-leak leg guards for extra protection.

Hypoallergenic, dermatologically tested, and latex-free, they also fit just like regular undies. No bulk. No crinkle sounds. No stress. Just one less thing to worry about.

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.

✔ Holds up to a full night’s wee (even for heavy wetters)

✔ Absorbent enough for sleepovers, overnight trips, and long car rides

✔ Helps keep bedding dry and mornings drama-free

 

Because not every child is dry by a certain age, and not every need is short-term. 

Nundies are designed to support kids and teens who need dependable, ongoing protection — no fuss, no judgement.

✔ Trusted by families managing ongoing continence needs

✔ Sensory-safe design — no scratchy seams, no stiff bits

✔ Soft, flexible fit for comfort at school, home or in care settings

✔ Familiar, undie-like feel that supports routine and independence

Daily wear? No problem. 

Nundies are gentle on skin and tough on leaks — without any chemical nasties.

✔ OEKO-TEX® STeP certified for material safety

✔ Dermatologically tested & hypoallergenic - expert tested to be safe for skin

✔ No fragrances, preservatives, chemicals, phthalates, or latex

✔ Gentle on even the most sensitive skin

Looks like underwear. Feels like underwear. Works like a highly absorbent incontinence pant. 

Win-win-win.

✔ Low profile — stays invisible under clothes

✔ Rustle-free design for quiet comfort

✔ Slim enough for fitted pyjamas or school uniforms

 

Smells? Sorted. No worries.

Nundies use smart odour-neutralising tech that keeps pH low to help stop the bacteria that cause both smell and skin irritation.

✔ Smart odour-neutralising tech keeps pH low to fight bacteria

✔ Keeps skin happy by helping reduce bacteria that can cause irritation

✔ Stays fresh for up to 12 hours, without added fragrance

Nundies are made to perform — without costing the planet more than they should.

✔ Manufactured in carbon-neutral facilities

✔ Powered by renewable electricity

✔ No palm oil or animal-derived ingredients

✔ Plant-based fluff (cellulose)

✔ FSC-certified packaging with 15% recycled plastic

✔ Every Nundies order with us = one tree planted

Stays put without squeezing, pinching or leaking. 

Whether they’re sleeping, running, climbing or fidgeting — Nundies hold up.

✔ Latex-free elastic anti-leak cuffs at the legs

✔ Flexible fit that moves with your child

✔ Won’t sag, ride up, or shift out of place

✔ Tried and tested for play and sleep

Fully breathable to keep things cool & comfy  — whether that’s through school, rest, or overnight.

✔ Materials that allow airflow to the skin

✔ Reduces build-up of moisture and heat

✔ Helps prevent sweat rash and dampness

✔ Feels soft, not sticky or sweaty

Waist: 50-70cm 

Weight: 17-30kg

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 Youth Pants 4-7

    My autistic daughter seems to have taken well to these and they do what they are supposed to do. Only negative is that some of the nappies you can’t see the “back” writing but I have figured out what side is the front so no longer an issue.

    Nundies Youth Pants 4-7years

    I use Nundies for my 5yr old girl, she has Level 3 ASD and still cant use toilet, so theses youth pants are really good for her! I go through 10-15 a day with her just cause she doesn't use the toilet at all, but they are really good for her size, shes about 24kgs but normal huggies do not fit anymore, these hold heaps, fit well and last long!
