Merino wool: the natural wonder for your baby
When summer comes, you want your baby to feel cool and comfortable. Often, parents think of wool as thick, warm sweaters for the winter – but merino wool is different. This unique material, derived from the merino sheep, has a smart fiber structure that regulates temperature. This keeps your baby warm in the winter and cool in the summer. Perfect for our changeable Dutch weather!
How does merino wool work?
Merino wool is a natural fibre that works like a small climate system. The fibres are fine, soft and elastic – ideal for sensitive baby skin. What makes merino wool so special?
- ✅ Temperature regulating: retains heat in cold conditions and dissipates heat in hot conditions.
- ✅ Moisture absorbent: absorbs up to 30% of its own weight in moisture without becoming clammy.
- ✅ Breathable: allows air to circulate, prevents overheating.
- ✅ Antibacterial: stays fresh longer, less washing required.
- ✅ Soft and non-itchy: perfect for your baby's sensitive skin.

Why merino wool in summer?
Many fabrics, such as cotton, retain moisture and feel clammy. Synthetic fabrics such as polyester do not breathe well and can become stuffy. Acrylic – a common fibre in knitted baby clothes – is also not a good choice. Acrylic is a completely man-made fibre that does not breathe and retains heat. This can cause your baby to quickly become too warm and sweat, which increases the risk of skin irritation and overheating.
Merino wool, on the other hand, actively wicks away moisture and regulates temperature, keeping your baby cool even on hot days. It feels light and airy, like your baby is wearing their own natural air conditioner!
The benefits of merino wool for your baby
- ✅ Keeps your baby cool in summer and warm in winter.
- ✅ Prevents heat rash and skin irritations.
- ✅ Absorbs sweat, stays dry feeling.
- ✅ Natural UV protection – ideal for outdoor play.
- ✅ Hypoallergenic and perfect for babies with sensitive skin.

Merino wool vs. cotton, polyester and bamboo
Where other fabrics fall short, merino wool shines. Cotton is soft but retains moisture. Polyester is synthetic and less breathable. Bamboo is eco-friendly but lacks the temperature regulation of merino wool. Merino wool combines softness, comfort, breathability and temperature regulation – all in one.
Is merino wool sustainable?
Yes! Merino wool is a renewable fibre – sheep grow a new fleece every year. It is biodegradable, meaning it doesn’t leave behind microplastics. In addition, many suppliers produce their wool under strict ecological standards, making it a conscious choice for parents who care about the world of tomorrow.
