Slim fit trousers Super 140s wool Petrol blue - Basket weave

Super 120’s, 130’s, 150’s…

The grades given by the IWTO (International Wool Textile Organization), known as SUPER 120’s, 130’s or 150’s, denote the fineness of a wool fibre used to weave a fabric. The higher the figure, the finer the fibre. The diameter of every 100’s wool fibre must measure no more than 18.75 microns. The 110’s should be 18.25 microns, the 120’s 17.75 microns… you just have to take away 0.5 microns to know the subsequent diameters.
