Children’s onesie is made from fine merino wool weighting 145g / m2. It is thin, soft and light, making it very breathable and giving it thermo-regulatory properties.

As a parent, you can be sure that your child is not overheating or sweating. Thin merino wool is excellent for children’s summer clothes or as a base layer during the winter. It offers natural UV protection, maintains optimal body temperature and prevents the body from overheating. That is why there is a long-sleeved version of this onesie.

Unisex color, which will match the women’s KOJO collection, makes this piece ideal for all outdoor experiences and trips. Your child will feel comfortable. It is perfect for newborns and children with very sensitive skin.

The onesie can be worn for a very long time thanks to the double sizes, the option of adjusting the length between the legs, cuffs that can be adjusted and the natural elasticity of the material. It is an investment that pays off. The cheerful design is complemented by a milky KOJO splash on the chest.
Choose a women’s London blue or Bordeaux pink t-shirt in the same color to match your little one 🙂.

Onesies are made in Slovakia.
