4,000 years before Gore-Tex, they invented... Oh my God! Then the world almost forgot
4,000 years before Gore-Tex, they invented... Oh my God! Then the world almost forgot. In the brutal cold of the Arctic—where a single mistake with your clothing could mean freezing to death or drowning in icy water—Indigenous communities created something modern science still marvels at: waterproof, breathable fabric. But they didn't use petroleum products or laboratory chemistry. They used intestines! The Inupiat of Alaska, the Yupik of Siberia, the Inuit of Greenland and Canada—Arctic peoples across thousands of miles developed the same ingenious technology independently. They turned the intestines of seals, walruses, whales, and even bears into garments so sophisticated that when Western scientists finally studied them, they found engineering principles that wouldn't be "invented" in factories until the 1970s. Here's the problem they were solving: Arctic hunters spent hours in kayaks on freezing water. They needed protection from rain, ocean spray, and wind....
