Yes.

The reinforced knees on Babbily trousers are designed to last significantly longer than those on standard children's trousers.

Many conventional fabrics begin to show wear after around 5,000 Martindale abrasion cycles. The reinforcement used on our outdoor trousers and leggings has been tested to withstand approximately 100,000 Martindale cycles—many times the abrasion children typically create during everyday play.

Like any fabric, it has its limits. Repeated knee slides across smooth indoor sports floors—think football goal celebrations—generate extreme friction and heat that can damage almost any textile. But for the adventures children tackle every day—climbing, crawling, kneeling, sliding and exploring—our reinforced knees are built to keep up.

Orientiere dich an der aktuellen Körpergröße deines Kindes.
Babbily-Größen wachsen über mehrere Größen mit und sitzen am Anfang bewusst etwas lockerer.

Für mehr Wachstumsraum: Wähle nach der aktuellen Körpergröße.
Für körpernäherer Sitz: Wähle eher eine Größe kleiner – mit entsprechend weniger Wachstumsreserve.

💡 Mitwachsen braucht Platz – nicht nur in der Länge, sondern auch in der Weite.

Designed for a Full Year of Adventure (and Beyond)

While standard trousers often give up after just a few weeks, Babbily is built for the long run. By combining ultra-tough knees with a grow-with-me fit, our trousers often last over a year—and are frequently passed down to younger siblings afterward.

To make the most of your Babbily gear:

Buy the current size: No need to "size up." We’ve already built the extra room into the design so the reinforced knees sit exactly where they should from day one.
Gentle Care: Washing at 30°C inside out protects the organic fibers and extends the life of the garment.
Give it a rest: Alternating with other trousers allows the natural fibers to recover and stay strong for even more adventures.

Why 100,000 Martindale abrasion cycles?

Care

Your leggings will stay soft and look their best for longer with a little care:

Babbily Children’s Thermal Leggings offer the perfect blend of comfort, durability and sustainability for your little ones. Our warm winter leggings are super comfortable for your child to play indoors and out, and are an essential addition to your kid’s everyday nursery and school wardrobe.

Super comfortable winter kids leggings to wear every day

Imagine asking your child to do yoga or sports in stiff jeans. Sounds uncomfortable? Children are always on the move and aktive, and they deserve comfortable clothing that keeps up with them.

That’s why our children’s thermal leggings are packed with features for maximum comfort. The high waistband provides excellent coverage at the back and you can easily adjust them for a good fit. Plus, there’s a gusset for wide steps to do cycling, skiing, sledging and all the fun winter activities. These warm leggings are ideal for daily play indoors or make a fantastic base layer for wintertime fun like skiing and sledging.

Made from soft and breathable organic cotton, Babbily winter leggings will keep your child warm and comfortable indoors or outdoors. The brushed terry fabric adds extra warmth on chilly days, making them ideal for winter wear. If your child isn’t a fan of layering, no worries – just pop on a pair of these warm winter leggings, and they’re good to go. (But you can also layer them with tights for added warmth or use them as a base layer under waterproofs or ski trousers.)

Available in sizes from 80 to 140, our winter leggings are perfect for kids of all ages, from kindergartners to school-goers.

Durable warm leggings to wear for several seasons

We believe in quality over quantity. We make our warm leggings from high-quality organic cotton terry that’s been thoroughly tested for wear and tear. To withstand the rigours of active play, we’ve reinforced the knees with an abrasion-resistant, high-tech sports fabric. This means no more worrying about knee holes or tears, and these leggings can even offer a bit of protection from the occasional tumble.

What sets our leggings apart is their ability to grow with your child. With an easily adjustable waistband and length, Babbily leggings can accommodate your child for up to four sizes. They start with a loose fit and move to a tighter fit as your child grows.

This grow-along design in combination with durable fabrics ensures that our warm leggings can be worn for several seasons and then passed on to younger siblings or friends.

Sustainable kids’ clothing

At Babbily we are committed to sustainability and reducing our impact on the environment. Our thermal leggings are not just about comfort, but also about making responsible choices. Yes, you can find cheaper leggings on the market, but your child will outgrow them vey quickly. Babbily leggings are made to last. One pair can outlast several cheaper alternatives, reducing overall clothing consumption and waste.

We carefully source our fabrics from GOTS-certified suppliers in Germany, the Netherlands and France to ensure the highest quality while maintaining environmental standards.

Our production is based in Europe, supporting local small businesses and social enterprises. By keeping our supply chain in Europe, we minimise our carbon footprint and contribute to a more sustainable future.

Your child will love the comfort, you will love the durability

Our Children’s Thermal Leggings are all about comfort, durability and making a positive impact on both your child’s comfort and the environment. You can count on Babbily to provide your child with super comfy clothing that lasts, reduces waste, and supports local businesses.

Babbily: Clothing Made to Last — for Children and for the Planet

Children grow fast. Their clothes often don’t keep up — especially at the knees. Many parents know the cycle: a new pair of trousers lasts only a short time before it needs replacing.

Babbily was created as an alternative to fast fashion. Our focus is simple: make children’s trousers that can be worn longer, passed on, and enjoyed through everyday play.

Why longevity matters

The most sustainable garment is usually the one that doesn’t need to be replaced. Because Babbily trousers grow with the child and are reinforced where wear happens most, one
pair can often replace several conventional pairs.

Based on average production data, choosing one pair of Babbily play trousers instead of multiple
short-lived alternatives can help reduce environmental impact:

Around 3,000 litres of water saved — roughly the amount used for 20 household baths
About 6 kWh of energy conserved — comparable to charging a smartphone hundreds of times
Approximately 4.5 kg of CO₂ avoided — emissions linked to producing additional garments

These numbers are estimates, but they help illustrate how durability can make a difference over time.

Thoughtful production, close to home

Sustainability for us is less about big promises and more about everyday decisions — where materials come from, who makes the clothes, and how far they travel.

Made in Europe
We produce in Austria, Slovakia and neighbouring regions, helping keep transport distances short.
Working with family-run ateliers
We collaborate with small manufacturers who combine craftsmanship with fair working conditions.
GOTS-certified organic cotton
All fabrics are certified according to the Global Organic Textile Standard (KIWA BCS 26126 & Control Union 1010800), meaning no harmful chemicals and gentle materials for sensitive children’s skin.
Plastic-free packaging
Orders are packed using recyclable, low-impact materials — simple solutions that reduce unnecessary waste.

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

We choose to manufacture in Europe because it allows us to work closely with our production partners, and continuously monitor and improve the quality, fit and durability of our products.
