 The Icelanders were having trouble selling their faux furs so when the king asked them if they would make a present to him of one of the furs, which happened to be grey, the sailors did not hesitate and the king immediately used it as a cloak.This set an instant fashion trend and before long the Icelanders had sold their entire load of previously unsalable furs to the kings men and the locals.Harald was ever after known as Harald "Gray-hide".
