Meet MyloTM

Made from mycelium, the underground root-like system of fungi, Mylo™ is a bio-based leather alternative that is soft, supple and less harmful to the environment.

The material that sparked a “mushroom leather” movement, Mylo is made possible by the world-class scientists and engineers at Bolt Threads and is backed by pioneering brands like adidas, lululemon, Stella McCartney, and more.

Why
UnleatherTM?

Leather has served humans for centuries. But people evolve, and so should our materials.

In our resource-constrained world with a growing population, we are overdue for a renewable, sustainable alternative to leather. The time is now to embrace new frontiers of possibility and unleather the products we use every day.

Unleather

[ən-le-t͟hər]

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

Deep Science Meets High Design

Magical thinking meets radical intention. This is a mission that never compromises what's possible for what's easy or accepts the old way as the only way.

Enter the Mylo consortium — a group of world-class companies investing in meaningful material innovation.

Intentionally selected for their exceptional product quality, impactful global reach, and proven commitments to innovation and sustainability, these companies are coming together, across competitive lines, to help create a more sustainable future for fashion.

STELLA’S JOURNEY WITH MYLO

Stella McCartney has never settled for the status quo. A visionary whom Vogue once called “fashion’s conscience,” Stella redefines luxury by never using animal leather, skin, fur, or feathers in her collections. As one of the first designers to ever use Mylo in her studio, the pioneering designer has been instrumental in bringing Mylo to life.

I believe the Stella community should never have to compromise luxury and design for sustainability, and Mylo makes that a reality.

— Stella McCartney

The bustier top and utilitarian trousers were handcrafted from panels of Mylo laid on recycled nylon scuba at the brand’s atelier in London. Months later, Stella introduced The Frayme Mylo at Paris Fashion Week as part of her fungi-inspired Summer 2022 collection. The first handbag of its kind to walk a major fashion week runway, The Frayme Mylo promises to bring Stella fans a sustainable update to an already beloved style.

INNOVATING WITH ADIDAS

In April 2021, adidas debuted the Stan Smith Mylo™, the first-ever shoe made from Mylo. To showcase the future of material innovation, adidas chose to use Mylo in one of the most iconic sneakers of all time, the Stan Smith. This reimagined classic enables adidas to quickly scale Mylo through a globally beloved silhouette, paving the way for a better future while paying homage to their heritage. The outer upper, perforated 3 stripes, heel tab overlay, and premium branding are all made with Mylo, and the midsole of the shoe is made with natural rubber to unlock a more sustainable future.

This is larger than sports, this is for our future.

More than a global leader in the sporting goods industry, adidas has been a longstanding pioneer in using eco-innovative materials to minimize its environmental impact. The brand has proven its commitment to sustainability through innovative partnerships and material exploration. As a consortium member, adidas has provided critical feedback in the development process to help give Mylo the strength and performance it demonstrates today.

MYLO IN PRACTICE WITH LULULEMON

Athletic apparel brand, lululemon, revealed the world's first Mylo yoga accessories in a capsule collection including a concept yoga mat made entirely from undyed Mylo. The first brand to use the material in a product beyond those traditionally made with animal or synthetic leathers, the yoga mat was designed to demonstrate Mylo’s future potential for use in products for a healthy lifestyle and environment.

Leveraging a material like Mylo demonstrates our commitment to creating a healthier future through low-impact products, paired with the performance-driven and high-quality design we’re known for.

Designed with the brand’s Science of Feel principle at the forefront, the collection includes two bags available for purchase. The Meditation and Yoga Mat Bag and Barrel Duffel Bag both feature premium, tactile embellishments made from Mylo, including intricately woven handles and braided zipper pulls that showcase Mylo’s soft, supple, and earthly hand feel.

Familiar Material, Radically Transformed

Mylo products have an unmistakable resemblance to traditional leather goods, but are designed for a lower environmental impact.

A community of visionary brands and global supply chain partners – who share really good chemistry – have helped hone Mylo’s finishing to achieve a range of colors and textures, with more offerings to come.

In addition to products from consortium partners, pioneering brands like Mercedes Benz and GANNI continue to explore and develop Mylo's product possibilities. Across fashion and sportswear, Mylo is now in the design studios of industry leaders.

From the Earth, For the Future

For billions of years, mycelium has grown beneath our feet and served as an ecological connective tissue. A sprawling, infinitely renewable, interlaced web, it threads through soil, plant bodies, and along river beds to break down organic matter and provide nutrients to plants and trees.

Mushrooms are the fruit of mycelium. Much like the branches and vines that grow apples or grapes, mycelium functions like these twisting, branching supports just under the Earth's surface.

On a mission to harness the promise of advanced materials science, a team of visionary scientists and engineers at Bolt Threads have developed a state-of-the-art process to grow and transform mycelium into a​ high-quality alternative for animal and synthetic-based leather.

The process begins with mycelium cells grown on beds of sawdust and other organic material. Billions of cells grow to form an interconnected 3D network which is processed, tanned, and dyed to make Mylo.

All of the Leather, None of the Animal

Mylo consumes significantly less land and emits fewer greenhouse gases than raising livestock. The material is certified bio-based, which means it’s made predominantly from renewable ingredients found in nature. It is verified vegan through DNA testing and supply chain assessment, ensuring zero animal products are used from end to end.

The mycelium used to make Mylo is grown in less than two weeks using just mulch, air, and water in a vertical agriculture facility that is 100% powered by renewable energy. It is then harvested and processed into material form using Green Chemistry principles. This highly efficient process is rigorously designed to reduce environmental impact from start to finish.

Mylo supply chain partners all meet top sustainability certifications.

These statements are based on bio-based testing and certification by DIN CERTCO, vegan verification through the Eurofins Chem-MAP assessment program, and preliminary environmental impact calculations. A preliminary impact assessment indicates the incredible environmental benefits of mycelium-based leather. In 2022 a full LCA will be released to provide a deeper view into Mylo's impact.
