Ecovative Collaborative Pilot
The aim of the pilot was to develop and test the next generation of mycelium-based alternatives to leather and foam materials. This project, spanning from December 2021 to March 2024, involved collaboration with major fashion brands to create sustainable materials suitable for consumer goods.
What's the challenge?
Leather production can have varying environmental impacts depending on the practices and standards employed. While some traditional leather is produced using responsible and sustainable methods, there are also growing concerns around its environmental footprint. While there are multiple “vegan” leather alternatives available on the market, many of them contain synthetic materials, have worse performance metrics than conventional leather, or are not available at scale. These partly plastic materials cannot be recycled and fewer still are compostable. Alongside this, synthetic foams, often made from polyurethane, are made from petroleum, a non-renewable virgin resource.
There are lots of opportunities for innovation in both leather and foam alternatives: Ecovative’s petrochemical-free mycelium hides and foam alternative promises to be a more sustainable alternative, grown in a fraction of time compared to animal leather, and with minimal resources.
Executive Summary
The Ecovative Collaborative Pilot was launched in December 2021 in collaboration with Bestseller, Pangaia, PVH Corp., Reformation and Vivobarefoot alongside manufacturing partner Ecco. The pilot aimed to test, refine, and scale Ecovative’s Forager AirLoom™ hides and MycoFlex™ foam. The primary goal was to develop sustainable, scalable alternatives to traditional leather and synthetic foam, minimising environmental impacts. Through collaboration with PVH Corp., Bestseller, Vivobarefoot, Pangaia, and Reformation, the project successfully scaled the production of these materials and demonstrated commercial viability.
Goals of the Project
-
Develop and test mycelium-based alternatives to leather (Forager AirLoom™ hides) and foam (MycoFlex™ foam).
-
Refine these materials for scale-up and commercial production.
-
Collaborate with brand partners to produce concept products.
-
Ensure commercial-scale production of these materials for future consumer goods.
-
Project Results
-
Validation of mycelium farming and tanning at scale: Ecovative developed a scaled supply chain within the EU (Netherlands) including a commercial farm partner and leading tannery (ECCO Leather) that enabled larger production volumes of raw mycelium and finished products.
-
Growing conditions impact material characteristics: Through the Mycelium Foundry One, Ecovative demonstrated that the performance of the final material can be successfully altered by changing the growing conditions to produce a range of products.
-
Promising results demonstrate multiple application areas: Material performance testing showed significant improvement for Forager AirLoom™ hides and MycoFlex™ Foam by increasing product uniformity and nearly tripling the strength of the raw mycelium.
Next Steps
-
Co-development is key: Ecovative continues to collaborate with several brand partners individually focusing on product development.
-
Further validation of product at scale: Ecovative and its regional supply chain partner continue to focus on scale and product quality.
-
Products on the market in 2025: Along with brand partners in and out of the pilot, Ecovative is focused on bringing Forager AirLoom™ hides and MycoFlex™ foams to consumer products on the market in 2025.

Ecovative
Ecovative utilises mycelium and agricultural waste streams to develop products with applications in food, fashion, beauty and other industries. The Ecovative Mycelium Foundry is built on an extensive library of fungal strains to test and perfect new mycological materials. Strains selected from this process go through their proprietary AirMycelium™ process to grow unique bio-materials fine-tuned for specific applications e.g. as leather alternatives.

PVH, Bestseller Get ‘Priority Access’ to Ecovative’s Mycelium ‘Forager Hides’
PVH and Bestseller are first in line to trial Ecovative’s mycelium “Forager” hides in a new cooperative revealed today. Alongside the brands, Amsterdam-based nonprofit Fashion for Good (which Ecovative has been working with for the past three years) is also a strategic partner as Ecovative refines production.
Pangaia, Vivobarefoot, Ecovative to Research Mycelium in Fashion
The collective mycelium research pairs Vivobarefoot and Pangaia with Ecovative’s team of mycologists, engineers and designers, to develop a line of fungus-based, petroleum-free foams and hides for their products. It also sees the three join the Fashion for Good Cooperative.
The Race for Fashion’s Leather Alternatives Heats Up
Ecovative wants to become the first to offer a plant-based leather alternative that’s ready to scale, and could up the ante in fashion’s race for leather replacements that are both more sustainable and higher quality, with a more attractive look and feel, than plastic-based vegan materials.
“Oftentimes with these different materials, you get a proof of concept that comes out and it takes time for these materials to then scale,” says Georgia Parker, innovation manager at Fashion for Good.
Other Projects
Sorting for Circularity Rewear
Fashion for Good expanded its Sorting for Circularity framework to address the challenge of sorting for rewearable textiles to understand better their resale potential and the demand across the second-hand market. We launched an 18-month initiative in January 2024 in collaboration with Circle Economy, brand partners adidas, Inditex, Levi Strauss & Co. and Zalando to enhance the sorting of rewearable textiles using innovative AI technologies. The project seeks to improve garment recovery for resale, promoting circularity in the fashion industry.
Behind the Break
Behind the Break is a multi-phase research initiative developed by Fashion for Good in collaboration with The Microfibre Consortium. The project takes a research-led approach to advance the fashion industry’s understanding of fibre fragmentation, addressing uncertainties in existing testing protocols and key knowledge gaps. By supporting the development of a more credible and consistent foundation, the initiative aims to enable stakeholders to make informed decisions and take decisive action to mitigate fibre fragment pollution, while leveraging the best available science.
Behind the Break 2.0
Behind the Break 2.0 is a targeted research initiative focused on addressing fibre fragmentation in textiles, building directly on the work started in Phase 1.0 (2024–2025), which tested the strengths and limitations of different methods used to measure fibre loss, identifying how much results vary between labs, and exploring what drives fibre shedding across three fabric types: cotton knit, cotton woven, and polyester knit. Phase 2.0 seeks to increase confidence in data quality, consolidate and refine existing testing approaches and knowledge across selected fabric archetypes, and deepen supplier engagement to support wider data collection within the space.
