Locks In Leaks

Built-in Odour Control

Low Profile Fit

Seriously Skin Safe

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.

For kids aged 4-7 years
Weight: 17-30 kg
Waist: 40-70 cm

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

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

Before you put your Nundies on, 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.

    Perfect product for my autistic daughter

    Struggled to buy nappies to fit my 4 year old who is very tall and big for her age, she has autism and is non verbal and is still in nappies, these keep her dry and less messes!

    We love nundies!

    My son is autistic and not yet toilet trained. We were buying supermarket size 8 pull ups then realised he was growing out of them. I was in a panic as there wasn’t a size 9 in the brand we used. Then I found nundies. Alittle hesitant at first so I bought 1 pack and thought if they don’t work then I’ve not lost much money. They fit Harry perfectly - he’s coming up 6. He’s a slim build so I’m confident this size will likely be the one for a few years yet. There really absorbent and he gets changed once a day at school so it means he’s not missing class too much with multiple changes. We’ve not had any accidents or leaks since changing to them . He wears them during the day and through the night also. No night time changes either. We now have them on auto delivery and buy them in bulk. I keep half at home and half at school so he’s always got his nundies.
