Made from black and white knit fabric, it features long sleeves and is perfect for everyday wear or for school activities.

The labels do not say what the materials are for some reason.

My best guess is that it's a poly/acrylic/wool blend. It has some stretch to it! but looks fuzzy like wool Not sure if that helps....sorry!
