I also can't say for sure what these tights are made of, but since they are a pair of Troll tights from the eighties I feel sure that they are made from 80% nylon and 20% lycra, for this mixture was not only used by Troll these years, but also by many other brands at that time - and is still much used nowadays. But I had never seen this distinctive giraffe pattern on other tights than Troll's.
