Growing gray children’s merino onesie with the KOJO print was also created in collaboration with the community Kids Who Explore, which aims to inspire families to go outside, connect with nature and each other.

The material we used to make this model is fine 100% merino wool with a mulesing-free certificate! Its weight is 220g / m2, so the onesie will be ideal year-round (except for the warm summer), either as a single layer of clothing or under the jacket in cold weather. 🙂 Merino wool is a thermoregulatory, antibacterial material, with natural UV protection and is also hypoallergenic. Merino wool clothes don’t even need to be washed often, it’s sometimes better to put them in the fresh air. Thanks to these properties, merino wool is ideal for children’s clothing. The onesie is perfect for fun outside, camping, hiking, or adventuring. Wet sleeves or sweating will not be a problem.

Thanks to the double sizes this onesie will last a really long time – the possibility to adjust the length between the legs, the cuffs that can be rolled up, and the natural elasticity of the material will pay off an investment. Our leggings for children in matching design will be the ideal bottom layer  – you will find them here.

Don´t forget about yourself 🙂 Your matching outfit – breastfeeding-friendly T-shirt can be find here.
