The remains of Ötzi’s goatskin coat, from the Copper Age, over 5,000 years ago. Scientific investigations indicate that the hides were tanned using fat and smoke. Once tanned, the sections were carefully cross-stitched together. The stitching was done with the fibres of animal sinews. The coat was worn with the fur side out. Darker stripes were alternated with lighter ones to produce a striking pattern.
