SIZE
Choose the size based on your child’s clothing size. The underwear runs a little roomy and high-waisted.
| Size | Clothing size |
|---|---|
| 90 | 80–92 |
| 100 | 98–104 |
| 110 | 110–116 |
- Tested: 14 months · 11 kg · clothing size 80/86 → size 90 fits well
- 2 years · 12 kg · clothing size 92 → size 90 fits well
- 4.5 years · 19 kg · clothing size 104 → size 100 fits well
- Clothing size 74 → size 90 is still too big
Garment measurements
Measurements are taken from the garment itself. The waist is measured flat and unstretched.

Between sizes?
Choose the smaller size. Because the underwear runs roomy, a size too big can slip down or leave a gap at the legs.
WASH & PRODUCT INFORMATION
To keep your UNDÉ underwear soft and comfortable, the print looking good and the pants performing at their best, please follow these care instructions.
-
Hand wash or a gentle cycle
Hand washing is the gentlest option for the fabric, print, waterproof layer, elastic and stitching. Machine washing is also possible: choose the Delicates, Wool or Hand wash programme with a low spin speed (400 to 600, or the lowest setting on your machine). Place the pants in a laundry bag and do not overload the drum. Avoid programmes such as Cotton, Synthetics or Intensive. -
Maximum 30°C
Wash at no more than 30°C. After an accident, rinse the pants in cold water first. -
Wash inside out
Turn the pants inside out. This reduces friction on the print and helps it stay looking good for longer. -
Liquid colour detergent
Use a liquid detergent for coloured laundry, and not too much. Powder and white or all-purpose detergents often contain bleach or optical brighteners, which make colours fade faster. -
Do not soak
Do not soak for a long time, as this may affect the function of the inner absorbent layer. -
No bleach, stain remover or fabric softener
Avoid bleach, stain removers containing bleach or oxygen, fabric softener and harsh chemicals. Fabric softener also reduces how well the absorbent layer works. -
Air dry
Hang the pants up straight after washing, preferably out of direct sunlight. To speed up drying, roll them in a dry towel and press out the water; do not wring. Do not tumble dry. -
Do not iron
Ironing is not recommended. -
Do not dry clean
This product should not be dry cleaned.
Good to know: how the absorbent layer and the print hold up after repeated washing also depends on your washing method and detergent. Follow the care instructions to help maintain their performance and colours.
Materials
- Outer fabric: 100% cotton
- Inner layer (against the skin): 100% cotton
- Absorbent layer: 100% polyester, with a water-resistant TPU layer

Warnings
Remove the tag and packaging before use and keep them out of reach of children. Training pants are not a replacement for a nappy. Use only under adult supervision. The waistband contains natural rubber latex, which may cause an allergic reaction in some people.

DIAPERS VS. POTTY TRAINING UNDERWEAR
Two different purposes. One important transition.
Diapers are designed for reliable protection, while potty training underwear is designed to help children notice wetness during potty training.
Potty training underwear isn't a replacement for diapers. It's a different tool for a different stage.
Tested by real families

HOW UNDÉ POTTY TRAINING UNDERWEAR WORKS
Designed to help them feel, learn and move.
UNDÉ Potty Training Underwear is designed to help children notice wetness, recognize when they need to go, and take small steps toward potty independence, while giving them a more underwear-like experience.
01
SOFT COTTON OUTER LAYER
The outer layer is made from pure cotton and designed to feel soft and comfortable against the skin.
02
MULTIPLE GAUZE LAYERS
Layers 1–6 are cotton gauze, creating a soft inner structure while allowing children to notice when they are wet.
03
ABSORBENT INNER LAYER
Layer 7 is an absorbent fabric made with terry cloth laminated with TPU, designed to absorb small amounts of urine.
04
COTTON INNER LAYER
Layer 8 is cotton cloth, completing the layered construction of the underwear.
DESIGNED FOR SMALL ACCIDENTS
Designed to absorb approximately 35–40 ml of urine and help reduce wetness on clothing and surrounding surfaces.
A WIDER ABSORBENT CROTCH
The widened crotch is specially designed to provide a larger absorbent area for small amounts of urine.
POTTY TRAINING, TOGETHER
Small steps are still progress.
Potty training is a gradual process. Children learn to recognise their body’s signals, practise getting to the toilet in time and slowly become more independent. Accidents can still happen along the way and that is a normal part of learning.
PRACTISE
Getting used to underwear, toilet routines and making it to the toilet in time.
ACCIDENTS
Missed signals and small accidents can still happen while new skills are developing.
INDEPENDENCE
Little by little, children learn to recognise, respond and manage more on their own.
There is no perfect timeline. Every small step is part of the journey.
DID YOU KNOW?
Awareness can grow through experience.
Children don't always recognise the feeling of needing to go before potty training begins. Sometimes, that awareness develops as they experience the difference between dry and wet and begin to connect it with what their body is telling them.
That’s where potty training underwear can become part of the learning process. It gives children the opportunity to experience wetness while wearing something that feels more like real underwear. Helping them notice, connect and gradually learn.
No perfect timeline. Just small moments of learning.
Loved by parents. Made for real progress.
Real-life experiences with potty training at home.

“We noticed that our little one became more aware of wetness. After an accident, the damp feeling helped us talk about what had happened and gently encourage the next trip to the potty.”

“We love that our child can practise wearing real underwear while learning to get dressed independently. It also makes the transition from nappy to underwear easier than practising with a bare bottom first and introducing underwear later.”

Questions parents often ask.
Everything you need to know about UNDÉ training pants: what they do and do not catch, which size to choose and how to care for them.
01How is it different from a nappy or regular underwear?
A training pant sits in between. It wears like regular underwear but has a few absorbent layers and a water-resistant layer in the gusset. A small accident is caught, while your child still feels wet. That is exactly what helps them learn the difference between dry and wet.
The gusset is wider and a little thicker than in regular underwear, and forms a kind of cup. A small wee stays there for a moment, giving the layers time to absorb it. The pants also sit higher in the waist. So they look a little different, but your child can still pull them up and down just as easily.
It is not a nappy: it will not hold a full wee.
02How much does a pair catch?
A small accident, such as a few drops or a small wee. That gives you just enough time to get to the toilet or potty, and often keeps the floor and sofa dry.
With a full wee, the pants may leak, especially at the sides. How much a pair catches also depends on your child and on how often it has been washed.
03Which size should I choose?
Choose the size based on your child's clothing size and the size chart on this page.
The pants are deliberately high in the waist and a little roomier around the waist and hips. This way they do not press on the tummy and catch an accident better. As a result, they look different from regular underwear.
Do not size up to grow into them: pants that are too big do not fit closely around the legs and may slide down. Not sure? Email us before opening a bag and we will help you choose.
04How many pairs do I need?
A washed pair air dries and is usually ready again the next day. So the number you need mainly depends on how many accidents you expect in a day.
Practising a few hours a day, or does your child usually have no more than one or two accidents a day? Then 3 pairs are enough. Leaving out the nappy all day, expecting several accidents a day at first, or does your child also go to daycare? Then 6 pairs are more practical.
05When can my child start?
There is no set age. Many parents start when their child shows interest in the toilet, lets them know the nappy is wet or dirty, or stays dry for longer periods. Every child goes at their own pace.
You can also use the pants to get used to them gradually, for example a few hours a day at home.
06How do I use the pants during potty training?
They work best when you are nearby, such as at home or on short outings. Remind your child regularly to use the toilet, for example after meals or before going out.
An accident? Change the pants and calmly name what happened: "You are wet, wee goes in the potty." This helps your child link the feeling to the toilet, without making it a big deal.
07Can my child pull the pants up and down by themselves?
Yes, that is what they are made for. The soft, stretchy waistband gives, so your child can pull the pants up and down by themselves. That helps them go to the toilet independently. Do choose the right size: pants that are too tight are harder.
08Can my child sleep in them?
The pants work the same at night as during the day: they catch a small wee. But a wee during sleep is usually a full wee, and the pants will not hold that. At night you also won't notice it straight away.
That's why we don't recommend them for the night yet. Use a nappy or night pant until your child usually stays dry at night.
09What are the pants made of?
The outer fabric and the inner layer against the skin are 100% cotton. The absorbent layer is polyester, with a water-resistant TPU layer. The waistband is polyester and elastodiene (natural rubber).
The waistband therefore contains natural rubber latex. If your child is allergic to latex, these pants are not suitable.
10How do I wash the pants, also after an accident?
After an accident, briefly rinse the pants in cold water. Then wash by hand or in the machine at max. 30 °C: inside out, in a laundry bag, on a delicates programme (on some machines Wool or Hand wash) and with a low spin speed.
Use a liquid colour detergent, no bleach or fabric softener, and do not soak for long. Hang them up straight away to air dry. No tumble dryer and no ironing. You will find all tips under Wash + care.
11Why are the pants sealed, and can I return them?
For hygiene reasons, each pair comes in a sealed bag. Through the transparent bag you can see the print and size before opening it.
You can return unopened pairs within 14 days of receipt via "Withdraw from purchase" at the bottom of the site. Return costs are at your own expense. Once the seal is broken, we can no longer take the pants back. If you return part of a bundle, the bundle discount no longer applies to the pairs you keep. Read more in our return policy.
12When will my order arrive?
Order on a working day before 4 pm and your order goes out with PostNL the next working day. In the Netherlands it usually arrives within 2–3 working days, in Belgium within 3–4 working days. You always receive track & trace.
Shipping within the Netherlands is free from 3 pairs. Read more in our shipping policy.
