Spider-silk

Bolt Threads, along with Germany’s AMSilk and Japan’s Spiber all develops "spider-silk", a type of silk fiber without the help of any spiders. It is a protein brewed with genetically engineered yeast and then spun into fibers. The fibers can be spin into yarn and then woven/knitted into a fabric. Stella McCartney works with Bolt Threads and have already developed some garments with spider silk.
