What are the leggings made of?

Main fabric

  • 95% organic cotton, 5% elastane
  • GOTS-certified (KIWA BCS 26126)
  • French terry (250 g/m²) – soft, breathable and holds its shape well
  • Reactive printed for vibrant colours that stay beautiful wash after wash

Reinforced knees

  • High-performance 4-way stretch fabric with Cordura®
  • Tested to 100,000 Martindale abrasion cycles
  • Water-repellent, dirt-resistant and highly abrasion-resistantWhy 100,000 Martindale abrasion cycles?

For comparison, many standard jersey fabrics begin to show wear after around 5,000 Martindale abrasion cycles. Our reinforced knees are designed to withstand everyday climbing, crawling, kneeling and playground adventures for much longer.

Buttons

  • Corozo (tagua nut) – a natural, biodegradable material

Care

To help your leggings last even longer:

  • Machine wash at 30°C, inside out, to help protect the colours and organic fibres.
  • Air dry whenever possible to preserve the fabric and reduce energy use.
  • Do not bleach or iron on a high heat.

Do the knees really last longer?

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.

How do the leggings grow with the child?

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.

How do Babbily trousers fit?

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 Größentabelle: Babbily-Größe, Körpergröße und mitwachsender Bereich

How long do the trousers fit?

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.

Product description

Some children love the look of jeans. They just don't love wearing them.

These Denim Pull-on Trousers Boys are super comfortable to wear everyday, yet robust enough to take anything life can through at them – from unplanned football sessions, to playground, to quiet reading on the floor. As well as being durable and comfortable, Babbily Denim Pull-On Trousers will grow along several sizes. That means they will last much longer than a pair of regular trousers.

You can easily adjust the waist with a buttonhole elastic. We know from experience that all other unnecessary fastenings – like zippers, cords and buttons – only get in the way and are never used. We’ve added a soft stretchy rib panel in the tummy area for extra comfort.

Babbily’s Denim Pull-on trousers are designed to grow along a few sizes. It is a smart combination of a high waist, turn up cuffs and generously cut knee protectors that always stay in place even when your child grows a few sizes. We put all our models through their paces in the playground for the best fit.

Fabric is the key for comfortable Denim Pull-On Trousers

These comfortable denim pull-on trousers with reinforced knees are made from soft organic stretchy summer-sweat fabric. It is which gentle on the skin and very pleasant to the touch. Thanks to the jeans-look design these denim pull-on trousers for boys look like jeans but give the comfort of pull-on joggers.

We only source our organic cotton from GOTS-certified suppliers. GOTS sets both environmental and social criteria for fabric production. We only work with certified GOTS fabric producers and make sure we choose the best quality fabric to make truly durable hand-me down pieces.

In addition to durable main fabric, robust knee protectors are made from very flexible abrasion resistant fabric developed for active sports. It is also perfect for children’s trousers! This fabric can withstand 100,000 rub cycles in the Martindale rub test.

With our Denim Pull-On trousers you will never have to mend ripped knees again!

Our approach to longer-lasting children's clothing

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.

Where is Babbily children's clothing made?

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.

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

Which leggings are best for nursery?

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.

Can my child put the leggings on and take them off alone?

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 waistband always pinches on other leggings. Is this one different?

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.

What if my child plays on damp ground?

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.

Are the patterned leggings as robust as the plain ones?

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.

Are denim-look leggings comfortable enough for the whole day?

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

Which season are the denim-look leggings suited to?

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

What is the difference between denim-look leggings and normal leggings?

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...

Die Hose passt perfekt und wächst über viele Größen mit. Wir hatten bereits die kleinere Größe, mein Sohn trägt sie sehr gern und sie ist wirklich sehr robust und gleichzeitig sehr bequem. Absolute Lieblingshose!

Top Hose, sieht sehr lässig aus und die Kniepartie ist (erprobter weise) sehr robust - andere Modelle, zu ähnlicher Zeit gekauft, sind da jetzt teils schon auf... unser Sohn ist auf jeden Fall begeistert. Einziger Wermutstropfen: der verstellbare Gummizug hat sich schon ein, zwei mal gelöst und ist dann im Bund verschwunden, das ist immer etwas fummelig wieder rauszuholen. Wird mich trotzdem nicht daran hindern, die in anderen Größen & Farben nochmal zu kaufen

Die Hosen halten wirklich alles aus und ich bin wahnsinnig begeistert von der Qualität und der Marke.

Unser Sohn liebt diese Hosen, sie sind die einzigen, die er in lang überhaupt akzeptiert. Am besten gefällt ihm, dass sie „perfekt zum klettern sind“. Sie haben unsere Beziehung wieder deutlich verbessert, da wir nicht mehr jeden Morgen diskutieren, ob und welche lange Hose er dann im Endeffekt in der Kita sowieso nach 10 min auszieht😅

Ich bin sehr begeistert, weil alle anderen Hosen von meinen Kindern nicht lange bestehen. Wir verbrauchen die alten oder geschenkten Hosen noch auf, aber sonst kaufe ich nur noch Babbly Hosen.
