Merle Kids' designs are all imagined and created to be great for all genders, and to just let kids be themselves! The leggings are designed to be super comfy and practical. The third panel at the crotch allows for maximum movement without tension (there are no crotch panels for the sizes 2-4 Y and 4-7 Y), while the very wide belly band ensures that the leggings stay up up up without putting any pressure on soft baby bellies. The bands at the belly and the ankles allow the leggings to grow with your little one. Just fold them over at first, and unfold them gradually as months go by! That way, the leggings can fit for a very long time. Merle's products are 100% designed and produced in Germany. Fabric: 95% organic cotton, 5% elastane
