Petäjä was born out of the founder’s deep insight into children’s winter lifestyles. We want children’s clothing to rise to outdoor challenges such as forest camping, hiking and horse riding, whilst staying light enough for everyday life in the city.

With the needs of children aged 0–6 always at its heart, Petäjä is committed to redefining winter performance standards:
From cosy indoor spaces to bustling streets, from lush green fields to snow-capped mountains, our patented, in-house-developed fabrics and premium high-loft goose down break down the boundary between warmth and bulk.

We encourage children to head outdoors and draw individuality, resilience and curiosity from nature.
Petäjä believes that no restraint should stand in the way of a child’s natural urge to explore.
We offer families around the world warmth for every setting, with expert, feather-light protection that supports every child’s freedom to grow.

In 2025, Petäjä introduces the new Gentle Care Collection, designed especially for little ones’ delicate skin and the many different moments of everyday life.Whether it’s light, playful movement indoors or a gentle stroll in the warm afternoon sunshine, we’ve chosen beautifully tactile, soft-feel fabrics to give children a delicate, skin-kind experience that follows their every move.This detail perfectly captures the very heart of Petäjä — bringing technology back to what children feel.We continue to explore the symbiotic relationship between down and children, safeguarding not only the courage to explore, but every bit of softness in everyday life.
