Navy half pants, size 150, made of 100% polyester. - Color: Navy - Size: 150 - Material: 100% Polyester Thank you for viewing. These are Hiraki gym class quarter pants. They don't pill even after washing, so they are recommended. Also, the length is a little shorter than half pants, so I think they are easy to move in during physical education class. New, unused, but it is a item stored by an amateur. No returns or refunds. No pets, no smokers.
