Meet Mylo

Mylo is a sustainable leather alternative made from mycelium, the root-like system of mushrooms.

As a material, Mylo delivers the timeless aesthetic and luxurious feel of leather, but without the planetary impact associated with raising livestock.

While cows require extensive resources and years to raise, the mycelium used to make Mylo is grown in less than two weeks inside a state-of-the-art vertical farming facility powered by 100% renewable electricity.

Our Brand

The material that started a “mushroom leather” revolution, Mylo™ was created by the scientists and engineers at Bolt Threads and is a mycelium-based leather of choice for world-class brands including adidas, Stella McCartney, and more.

Together with our growing network of brand partners, we've developed Mylo to meet the highest possible aesthetic and performance standards for high-end, lower impact products.

Why Unleather?

Leather is an amazing material. But at the scale it’s used today, it is simply unsustainable.

The global cattle industry — where the majority of leather comes from — has a massive environmental impact, producing roughly as much greenhouse gas as the United States.1

Because Mylo doesn’t require the enormous amount of energy, land and calories needed to raise livestock, we can offer customers all the beloved properties of leather but without the devastating environmental impact of cattle.



The radical act of choosing products made sustainably with infinitely renewable mycelium over animal and synthetic-based materials.

  • Mylo™ material is a sustainable leather alternative  made from mycelium, the root-like structure of mushrooms, created by the scientists and engineers at Bolt Threads, a material solutions company based in Berkeley, California with manufacturing facilities in The Netherlands.

  • The process to make Mylo™ material starts with reproducing what naturally occurs beneath the forest floor. Inside a vertical farming facility powered by 100% renewable energy, fungal cells are mixed with sawdust and organic material to grow dense mycelial networks that rise from the substrate and form soft foam-like mats.

    Once mature, the mycelium is harvested and the remaining substrate is composted. Guided by Green Chemistry principles, the mats are processed and transformed into sheets of soft, earthy biomaterial ready for surface texture and finishing by an LWG gold-rated tannery.

    For a closer look at the process, visit our Material page.

  • Products made from Mylo™ material are available directly from our growing network of brand partners. Product availability, release dates, distribution, and points of sale are controlled by partners individually.
