Do the knees really last longer?

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.

How long will a pair of Babbily trousers last?

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.
How do Babbily trousers fit?

Babbily trousers are designed to fit true to size, with room to grow.

To find the right fit, simply use your child’s actual height as a guide. Since sizing varies significantly between brands, we recommend sticking to their actual measurements for the best
fit.

Size Chart (Child's Height → Babbily Size)

  • 80–90 cm → Size 80+
  • 90–102 cm → Size 92+
  • 102–114 cm → Size 104+
  • 114–126 cm → Size 116+
  • 126–138 cm → Size 128+
  • 138–150 cm → Size 140+

Deciding Between Sizes?

Our grow-with-me cut is designed to be versatile, each piece is optimized for an average
build. But here’s how to choose based on your child’s build.

  • For Slimmer Builds: We recommend choosing the smaller size. This ensures the trousers fit perfectly from day one without any bunching or excess fabric.
  • For Average to Sturdier Builds: Go for the next size up. Thanks to our adjustable comfort waistband, the trousers will still sit securely while offering plenty of room for active play.

The Babbily Difference: Our Signature Waistband

Instead of a narrow, pinching elastic, we use an extra-wide, stretchy comfort waistband. It provides a secure hold without leaving pressure marks—perfect for a full day of movement and play.

What fabric are the trousers made from?

Main fabric

  • 100% organic cotton fleece
  • 305 g/m²
  • GOTS-certified (KIWA BCS 26126)
  • Thick, brushed fleece for natural warmth and exceptional softness

Reinforced knees

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

Why 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 trousers last even longer:

  • Machine wash at 30°C, inside out, to protect the organic fibres and Cordura® reinforcement.
  • Air dry whenever possible. While the trousers can be tumble dried on a low setting, air drying helps preserve the shape, elasticity and lifespan of the fabric.
  • Spot clean when possible. Light dirt on the reinforced knees can often be wiped away with a damp cloth, so the trousers don't need washing after every adventure.

Why children and parents love Babbily trousers

Perfect for kindergarten – indoors and outdoors

Babbily's fleece pants are perfectly designed to accompany children throughout the day. They combine the comfort of pull-on pants with the warmth of thermal pants , while boasting a classic cut that also looks great at school.

Children spend a large portion of their time at school, constantly switching between different activities. Sometimes they're sitting in the classroom, sometimes they're running around during recess – both indoors and outdoors. For this, they need comfortable clothing that not only fits well but is also easy to put on and take off.

It has to be breathable so children don't sweat, yet durable enough to withstand a soccer game during recess. Winter presents a special challenge: The clothing has to be warm enough to withstand the walk to school, but also comfortable to wear indoors.

Kindergarten pants - fleece pants for children who can do anything

That's where Babbily comes in. Our soft children's fleece pants made from pure organic cotton offer exactly the comfort that kindergarten children need. The fabric is especially soft on the skin and free from harmful chemicals. So your child can play safely and comfortably all day long. And when it's time for recess, the warm pants will keep them pleasantly warm even outside thanks to the organic cotton fleece. Once put on, there's no need to change them – ideal for every day. The wide, comfortable waistband with adjustable elastic on our children's fleece pants ensures that the back is always well covered and the warm pants don't slip down even during active games, and they fit well without being uncomfortably tight. Even with a lot of activity, these winter pants fit securely and keep the little ones warm and cozy, whether indoors or outdoors. Simply pure coziness.

Robust knee protection that delivers what it promises

We know how active children are. That's why we've equipped our children's fleece pants with extra-large knee pads. The fabric was specially developed for sports and motorcycle use and can withstand up to 100,000 friction cycles . This means that the knees of these warm pants are optimally protected without restricting freedom of movement. Thanks to the 4-way stretch, the fabric remains flexible and adapts to every movement. The knee reinforcements are also water-repellent, so a fall on a wet playground is no problem – simply wipe them down and they're clean as new. In our experience, the knee pads will withstand even the wildest adventures – holes are a thing of the past.

Adjustable fit for longer-lasting comfort

As with all Babbily trousers, we focus on a flexible fit that grows with your child. The waistband and leg length are adjustable, ensuring these fleece pants will fit children well over several seasons. Our "grow-with-me" pants adapt to your child's growth, so they can be worn for longer.

Practical bags for little explorers

We know every pair of pants needs pockets – for all the treasures of the day! That's why we've integrated side pockets for safely storing small treasures.

Soft organic cotton instead of recycled polyester: Why we rely on sustainable fleece

Although recycled polyester for fleece pants is often touted as a sustainable solution, we disagree. Washing polyester, whether new or recycled, releases microplastic particles that end up in our oceans—one of the main causes of microplastic pollution. Furthermore, polyester can't be recycled, meaning garments made from recycled plastic end up in landfills. And compared to natural materials like organic cotton, polyester isn't as breathable or skin-friendly. That's why we use natural, healthy, and chemical-free materials for our kids' fleece pants—because true sustainability starts at the roots.

Sustainability for tomorrow's adventures

Our children's fleece pants are made from 100% pure GOTS-certified organic cotton (Certified by KIWA BCS 26126). This means that strict ecological and social standards are adhered to during the production of the fabric. Furthermore, the long lifespan of our warm pants contributes to reducing textile waste and conserving resources. And: We manufacture in Europe, which guarantees short transport routes. We know our production partners personally and select them based on trustworthiness and fairness.

Developed for mothers who know what matters

We listened to our customers' feedback and developed warm pants that combine all the essential elements for comfort and durability. The wide, adjustable waistband and extra-large knee reinforcements ensure that these children's fleece pants are comfortable and durable in every situation—no matter your child's body shape.

Highlights:

  • Soft fleece made from pure organic cotton, GOTS-certified (Certified by KIWA BCS 26126)
  • Wide, adjustable comfort waistband with elastic band for a perfect fit
  • Extra large knee reinforcements made of robust, 4-way stretch, withstands 100,000 abrasion cycles
  • 2 side pockets
  • Grows by 3-4 sizes thanks to adjustable leg length and adjustable waistband
  • Breathable and warm – ideal for indoors and outdoors
  • Designed in Vienna, made in Slovakia

Babbily's children's fleece pants will be an indispensable companion throughout the winter – and beyond. Complement your child's winter wardrobe with a second pair of thermal trousers made of brushed sweatshirt fabric from Babbily, and your little hero will be ready for winter adventures.

How sustainable are Babbily trousers?

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.
Where is Babbily children's clothing made?

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.
