You’ll remember Bolt Threads from a striking yellow dress designed by Stella McCartney last year. She used a spider silk grown in Bolt Threads’ laboratory. The fabric innovators this week introduced the world to its second new-generation material.

Called Mylo, it is “the first commercially available take on modern leather grown from mycelium, the root structure of mushrooms.” Bolt Threads released a press release stating that the material looks and feels like hand-crafted leather. “Mylo is produced in days versus years, without the material waste of using animal hides.” The fabrication was pioneered by experts at Ecovative, while Bolt Threads optimised the technology and made it commercially ready for the market.

Mylo will be shown at the Victoria and Albert Museum’s Fashioned from Nature in the shape of a prototype bag, called the Falabella Prototype One (a Stella McCartney collaboration) which will be available to order from June.

Meet the team, and see their work in the video below.
