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.
Problem Statement
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
The Next Stride: Bio-based Materials for Footwear Soles
“The Next Stride: Bio-based Materials for Footwear Soles” aims to validate the performance and environmental impact of bio-based polymers as sustainable alternatives to the fossil fuel-derived materials currently used in footwear soles. The objective is to collectively de-risk the transition to these “next-generation” materials by rigorously testing their technical properties and assessing environmental benefits. Ultimately, the purpose is to accelerate the adoption of these bio-based solutions and pave the way for a more sustainable footwear industry.
Beyond50 Denim: Combining Cottonised Hemp And Green Chemistry
“Beyond50 Denim: Combining Cottonised Hemp And Green Chemistry” aims to validate the performance and environmental impact of cottonised hemp processed with green chemistry to act as a true alternative to cotton in denim applications. The project goal is to evaluate the performance of SEFF’s cottonised hemp fibre in combination with Fibre52’s bio-friendly chemistry solution within denim fabric applications with a total hemp content of 50% and above. The fabrics will be benchmarked against conventional 100% cotton denim with a specific focus on handfeel and aesthetic characteristics.
Price Parity Toolkit
The Price Parity Toolkit (PPT) was designed to help bridge the price gap between next-gen* and conventional materials. Developed by Fashion for Good with the support of Canopy, this industry-supported framework introduces a financing mechanism that decouples price premiums at early stages of the supply chain to enable adoption and drive the scale of lower-impact materials.
