Mylo looks and feels like hand-crafted leather

US-based biotechnology company Bolt Threads has developed what it claims is the world's first commercially available leather grown from mycelium, the root structure of a mushroom.

The firm creates fibres from scratch based on proteins found in nature, and then develops cleaner, closed-loop processes for manufacturing, using green chemistry practices. It claims to be the first company in decades to release two novel materials, the first being its biofabricated spider silk, Microsilk.

Now, Bolt Threads continues to use its technology as a platform to invent new and useful materials inspired by nature that are better for the planet.

Its latest offering – Mylo – looks and feels like hand-crafted leather, and because Bolt Threads can control the environment and process through which Mylo is grown, the firm is able to manipulate the leather's properties - durability, strength, and suppleness - making each product "one-of-a-kind".

In an announcement this week, Bolt Threads said it plans to bring Mylo to consumers by releasing its own bag for pre-order this June, while British design house Stella McCartney - a long-term partner to Bolt Threads - will also debut the Mylo Falabella Prototype 1 bag at the Victoria and Albert Museum's Fashioned from Nature exhibit, open to the public on 21 April in London.

Bolt Threads partnered with biomaterials company Ecovative on the launch of Mylo, to license the initial mycelium technology, and then perfect the process for commercial viability.
