This is a set of adidas NBA Cavaliers and Champion t-shirts. Both are size S. The tag on the white one also says 160. (My child wore these when they were about 155cm to 160cm tall, so I think they are equivalent to a kids' size 160.) Both are 100% cotton. Both have some wear and tear from use, but there is no major damage such as holes. However, the white one has a stain on the hem.
