The leggings are made of 95% organic cotton and 5% elastane (GOTS certified). The elastane ensures the fabric stays stretchy longer. These leggings are made of a nice, thick sweat jersey.
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 insures that the leggings stay up up up without putting any pressure on soft baby bellies. Moreover, 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.
For best care: machine wash on cool and air dry.
