Outwardly they look like leggings made of dense fabric, but inside they are made of fluffy fleece. They are suitable for wearing to school or other public places. The thermal insulation is very good. The label says 100% cotton, which is a major downside, assuming it's true. I would prefer polyester for its more weather and shrink resistant properties. The weird thing is that these leggings look like they are smooth and silky, like polyester, and when I drop water drops on them, the water drops like polyester. So I'm not sure how much I trust the fabric label here. Size 54 is suitable for children aged 9-11.
