Description

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.

Absorbency That’s Always On Duty

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

Made for Kids Who Need Ongoing Protection

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

Seriously Skin-Safe

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

Feels like Undies, Works like Magic

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

 

Real Odour Control

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

Smarter on Sustainability

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

Snug Where It Counts

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

Designed for Comfort

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

How to Wear

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!

    I finally found some diapers that really work for my 7 year old son. There is some escape from time to time, but nothing to do with daily escapes with diapers from other brands. I recommend them!

    Best pull-ups I've ever used.

    Honestly wish I had learnt about these sooner. My 6 year old son is just becoming dry overnight but before discovering Nundies we were having accidents almost every night as the store bought ones were not able to keep the liquid in. Great value for money, delivery is quick and I will always recommend them to anyone who needs that extra absorbency and peace of mind.

Frequently Asked Questions

What size do your youth nappies go up to?

We have two size options in our Nundies Youth Pants, the medium size to fit children aged from 4-7 years old and our large size for kids aged 8-15 years old.

What are your most popular youth incontinence products?

Nundies Youth Pants for ages 4-7 and 8-15 are our most popular brand for children and teens. Over 90% of those who reviewed our Nundies pants would recommend them to a friend.

Our waterproof bedding and protectors are also a popular add-on for parents and carers shopping for youth pants. These help protect a child’s bed and any furniture they use from leaks and add an added layer of confidence and comfort to their incontinence experience.

How do I know if my child's nappy is the right size?

Firstly, we recommend checking the weight of your child - this helps you know which size will be best.

Before you put the pants on your child, or before they put them on themselves, fold them in half lengthways and cup them back and forth a few times. This helps to soften them so they'll better fit to your little one's body and stay discreet under clothes.

Once the pants are on your child, make sure the leak guards around the leg holes are flared upwards towards the waistband. This makes sure you'll be protected against any leaks.

You can also check the fit of the pants when they're on your child to be sure the waistband and leg cuffs are fit snugly against the body, and aren't too tight.

If my child is over 15 and still needs pull-up pants, what can they use?

If your child is over the age of 15 and requires incontinence pants, you can try the smaller sizes from our adult unisex range.

If you need any guidance, our team of product specialists will be more than happy to help!

My child is still leaking during the night, what can I do?

If your child is still leaking at night, we recommend making sure that the leak guards at the leg openings are activated and flared upwards towards the waistband.

We also recommend checking the fit of the pants, and making sure they fit snugly to the waist and legs, without feeling too tight or uncomfortable.

If you're still having trouble, don't hesitate to contact us for more guidance.
