GOTS Organic Cotton: Made from certified organic jersey that is soft on skin

Made for movement, built to last.These leggings are designed to keep up with your child’s energy. We use high-quality materials that feel great and stay in shape, so they can focus on exploring.

The Fabric: 95% GOTS-certified organic cotton, 5% elastane (KIWA BCS 26126). Soft, breathable, and with just enough stretch for climbing and running.
Lightweight Jersey: At 200 gsm, the fabric is ideal for year-round wear—light enough for summer days and perfect for layering when it gets chilly.
Bold Prints: We use reactive printing to ensure the colours stay bright and don’t fade into a "washed-out" look after a few weeks.

How to look after them (and the planet): We believe in washing less and wearing more. It’s better for the fibres and the environment.

Cool Wash: Machine wash at 30°C. To keep the colours vibrant and the fabric smooth, we recommend turning them inside out before washing.
Air Dry: Skip the tumble dryer. Hanging them out to dry preserves the elasticity and keeps the fit perfect for longer.
Keep it Simple: No bleach, no harsh chemicals. If you must iron, keep it on a low setting.

Yes. The knee patches on Babbily trousers are specially developed to last much longer than ordinary children's trousers.

While many conventional fabrics show wear after around 10,000–20,000 rubs (source: apshan.com), the knee patch reached 100,000 rubs in the Martindale test (the knee patch was tested, not the whole garment) – many times the strain of normal everyday play. Actual durability depends on use.

Important: extreme knee slides on sports-hall floors – think football goal celebrations – can of course damage this fabric too.

For everything else children do – climbing, crawling, sliding, romping – the reinforced knees are made for it.

In three places:

Waistband: You can adjust the waistband to be tighter or looser using the buttonhole elastic. Once set, your child can pull the leggings on and off by themselves.
Length: The long leg cuffs are folded up at the beginning and rolled down bit by bit as your child grows.
Width: At the beginning, the leggings fit a bit looser, almost like trousers on slimmer children. As your child grows, they fit more closely to the body without feeling constrictive.

The knee patch is intentionally cut large so that it still covers the knee even after a growth spurt. This allows the leggings to accompany your child through 3–4 clothing sizes.

Go by your child's current height.
Babbily sizes grow across several sizes and deliberately fit a little looser at first.

For more room to grow: choose by current height.
For a closer fit: choose one size smaller – with correspondingly less growing room.

💡 Growing needs space – not just in length, but also in width.

Babbily trousers are designed to be worn for many months – often for a whole year.

The cut gives children plenty of freedom of movement and grows with them for a long time thanks to the elastic waistband and adjustable length.

Of course, how long they actually last also depends on how wild your child's adventures are. Many parents tell us, however, that their Babbily trousers are worn for over a year and then even handed down to siblings.

To make them fit and last as long as possible:

Don't size up

The room to grow is already built into the cut. That way the knee patch sits exactly where it should protect.

Wash gently

Ideally at 30 °C, turned inside out. This is gentle on the organic cotton and keeps the surface nice for longer.

Rotate

Natural fibres appreciate small breaks. If the trousers aren't worn every day, they keep their shape for longer.

These durable kids leggings with reinforced knees are perfect for every day play – be it at home, at a nursery or at a playground. Abrasion-resistant knees, adjustable length and waist and a wide step make these leggings perfect for any adventures.

Soft organic cotton makes Babbily leggings extremely comfortable and gentle on the skin. Thanks to the knee reinforcements – using fabric developed specially for active sport – our leggings are hard-wearing yet very flexible. Knee patches provide a bit of water protection should your child come across wet sand.

The durable kids leggings are fitting not too tightly and are cut to provide some more space for movement (hence treggings, a mix of trouser and leggings fit). They are good for both small girls and boys. Gusset allows for an extra wide step for all those step and tree climbers.

This winning combination of comfort and durability makes these leggings perfect for every day wear.

Life with children is full of surprises, but one thing you can be sure about – with these leggings holes in the knees are a thing of a past. Plus, because they are designed to grow with your child – up to four sizes! – you can buy a pair or two now and forget about shopping for the next year.

Stripy pattern at the front, back of the leggings is plain dark navy. Nappy allowance and a more relaxed fit for sizes 80, 92. Classic slim leggings fit from size 104.

Main features:

ROBUST – knees 5 times stronger

EASILY ADJUSTABLE – to grow 3/4 sizes

LONGER-WEARING – 12 month and more

SUPER COMFORTABLE – with an extra wide step and easy fit

SOFT – made with organic fabric

DESIGNED AND MADE IN AUSTRIA

We develop our GrowProof™ leggings with one simple goal: they shouldn't be too small or worn through at the knee while the rest is still fine.

Grows across 3–4 sizes
Waistband and leg length can be adjusted. So one size can accompany your child much longer than trousers with a fixed fit.

Knee patch tested to 100,000 rubs
The flexible knee patches are made of an abrasion-resistant 4-way stretch fabric and reached 100,000 rubs in the Martindale test.

GOTS-certified organic cotton
We use certified fabrics from our European suppliers. You will find the certification in the product details.

Made in Europe
Our trousers are produced in small batches in Europe, including in Slovakia.

European suppliers
We source fabrics and other materials from selected suppliers in Europe, including Germany, the Netherlands and Austria.

Small production businesses
We work with small family businesses and workshops that we choose for their workmanship, reliability and production quality.

Plastic-free packaging
Our orders are packed in paper-based packaging without plastic.

Wearable for longer – through construction, not promises

A grow-along fit and particularly abrasion-resistant knees can help a pair of trousers stay in use longer and be replaced less often because of growth or holes in the knees.

Our clothing is made in Austria, Slovakia and neighbouring European countries.

We work with small family businesses that deliver high-quality craftsmanship and
produce under EU labour law.

Organic leggings knee vs. Babbily knee reinforcement

Babbily Reinforced Knees - 100,000 Martindale Abrasion Cycles

What does 100,000 rubs mean?

It is an abrasion test: a machine rubs the fabric until it wears through. Our knee patch reached 100,000 rubs (the knee patch was tested, not the whole garment).

Good to know

Soft ones that are easy to put on by themselves and can take a lot at the knee. The GrowProof™ organic leggings have a wide, adjustable waistband without buttons or zip, lots of freedom of movement and reinforced knees – for morning circle, climbing frame and everything in between. The soft jersey made of
certified organic cotton is breathable and gentle on the skin, even when sitting on the floor for a long time.

Yes, that is exactly what they are designed for. There are no buttons, zips or cords on the outside: just slip in, pull up, done. You set the adjustable elastic in the waistband once – after that, your child doesn't need anyone's help for toilet trips at nursery.

The comfort waistband is wide and soft and sits without digging in. Because the width can be adjusted with the elastic, the leggings don't slip on slim children – and don't pinch on sturdier ones. The turn-up
leg cuffs also adjust the length.

The knee patch reached around 100,000 rubs in the Martindale test, is water-repellent and easy to wipe clean. For dry ground, sand and grass, the leggings are perfectly fine outdoors. In rain and real mud, simply put rain trousers over them. The knee patch is water-repellent, the leggings are not waterproof. This way the leggings stay the easy everyday trousers – indoors and outdoors, without constant changing.

Yes. Patterned and plain leggings are made from the same light summer jersey and have the same flexible 4-way stretch knee reinforcement against wear.

If your child plays outside a lot, we recommend our denim-look leggings: the slightly thicker summer sweat is even better suited to the playground and everyday outdoor life.

Yes. The fabric looks like denim but feels soft and stretchy. The high, adjustable waistband also makes them comfortable to wear.

The slightly firmer summer sweat is particularly well suited to spring, autumn and mild winter days.

Our denim-look leggings are a little thicker and more robust than the light jersey leggings. Both have the same grow-along cut and reinforced knees.

Also perfect for romping...

Wie immer eine großartige Lieferung mit einer Überraschung für die Kinder!! Die Hose ist sensationell! Vielen Dank!

Ich liebe diese Leggins - sehr robust und stylish ❤️

I love the fact that the waist can be adjusted to fit slimmer babies, like my boy. The leggings fit well and the colour is very practical - you can't see any dirt on them :)
