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.

Say goodbye to disposable clothes and make a more sustainable choice with Babbily. Your child will thank you, and so will the planet.

Our Babbily leggings are designed to last between 6 months and 2 years (or longer if passed down), depending on how often your child wears them and how active they are.

On average they can be worn for a year. Provided the size is correct and the knee patches fully cover the knees.

This is significantly longer than traditional trousers, which often wear out at the knees after a few months or even weeks.

What can you expect?

Our aim is to combine comfort with durability. We use high quality materials that are child-friendly and suitable for active use – soft organic cotton for comfort and durable fabrics from sports and motorsport for added strength.

Durable knee reinforcement:

The knee reinforcement can withstand 100,000 rub cycles on the Martindale scale. This means the fabric is industrially tough and can withstand falls and extended play on the ground.

Comfortable and skin friendly:

Our leggings are not designed to be ‘tough work trousers’ (which are often made from stiff fabrics), but comfortable and durable everyday wear. The main fabric, organic cotton jersey, is particularly comfortable, skin-friendly and breathable – ideal for daily use in school and nursery.

Durability:

The organic cotton jersey is durable, but may show signs of wear at the seams after very long use. In comparison, conventional leggings tend to tear at the knees much earlier.

The bottom line
Babbily leggings generally last between 6 months and 2 years (or longer if passed down). They are designed for everyday use and offer an excellent combination of comfort and durability.

Make sure you choose the right size so that the knee patches fully cover the knees, so that you can enjoy the leggings for longer.

These leggings are made from organic cotton brushed Fench Terry sourced in Germany. Abrasion resistant knee fabric sourced in Austria.

Composition:

95% organic cotton, 5% EL – brushed French Terry
Abrasion resistant knee fabric (withstands 100.000 cycles on Martindale rub test) – 73% PA, 14% PES, 13% EL
Corozo buttons (natural degradable material)

We recommend gentle wash at 30°C and tumble dry at a low temperature. Treggings will look and feel slightly bigger when new, but will shrink to the intended size after a few washes.

You can adjust the fit of the leggings at the waist, and you can also easily alter the length of the leggings with turn-ups.

Designed in Vienna

Our brand is all about doing things in a way that’s good for the planet. We make clothes that are really well made, so they last a long time and that helps reduce the amount of clothes that get thrown away.

But it’s not just about the clothes, it’s about the people who make them. We believe that if the people making the clothes are happy, the clothes will turn out better.

We design our clothes in Vienna. The materials we use are sourced from suppliers in Europe, like France and Germany. Even the little things we use, like buttons and zips, come from small businesses in Europe.

Because we’re a small brand, we can’t do everything ourselves. So we work with other companies who care about what they do as much as we do. Our clothes are made in small workshops and social enterprises in Austria, Slovakia and Poland. These places have a lot of experience and really care about making things well.

We’re doing our bit to take care of the earth for our children’s future, and we hope you’ll help by supporting businesses like ours.
