‘Super 100, 110, 120, 130 etc’ or ‘S100, S110, etc.’ is used to indicate the length of a sheep hair. A Super 150 suit is made from hairs that are finer and weigh less than a Super 100 suit. The higher this number, the more luxurious the suit. However, it also makes a suit more fragile and if the suit is woven of such light materials, the comfort might actually decrease again.
