At ISBJÖRN of Sweden, you'll find base layers for babies designed to give the very youngest a soft, warm and safe start to life outdoors. Since young babies find it harder to regulate their body temperature than older children, a functional base layer is an important part of their clothing all year round. As the first layer against the skin, the base layer helps maintain an even temperature while wicking away moisture and feeling comfortable against sensitive skin.

Our base layers for babies come as a practical jumpsuit that makes dressing easy and keeps the whole body warm and comfortably covered. The thoughtful design ensures the garment stays in place and works just as well on cold winter days as under lighter outerwear when temperatures vary.

Since the base layer is worn directly against the skin, material choice is crucial. That's why our base layers are made from a combination of RWS-certified, mulesing-free merino wool (Responsible Wool Standard) and FSC®-certified bamboo (Forest Stewardship Council). Merino wool helps regulate body temperature and stays warm even when damp, while bamboo provides an extra-soft feel against the skin and good breathability – a combination well suited to the very youngest all year round.

Sustainability is a natural part of every garment from ISBJÖRN of Sweden. Through carefully selected materials and manufacturing according to the bluesign® standard, we ensure responsible production with high standards for chemical management, resource conservation and care for both people and the environment.
