Set of 3 underwear, 100% cotton. One thick short-sleeved shirt, blue Two thick long-sleeved shirts, navy and white (Size 130, but listed as 120 because it runs small) The thick, sturdy fabric keeps you warm. I think there's a little yellowing on the white sleeves, but personally, I don't mind it much. There is some pilling, so please purchase if you understand that these are used items.
